  • Pure CSS Dropline Menu - second level menu items sit below their parent - but sometimes extend off s

    - by Simon
    Hi, I'm working on a pure css menu that consists of four levels Level 1 and 2 are a dropline menu in style Levels 3+ are dropdown menus When you hover over a level 1 menu item, the level 2 menu displays directly below menu item you are currently hovering over. However if there are lots of menu items on level 2 then the level 2 menu goes off the screen and you see a horizontal scroll bar. What I want to happen is that if the menu is going to go off the screen I want it to get pushed to the left. For example, if the menu was 300px long, but there was only 250px between the level 1 menu item and the edge of the page, then the level 2 menu should not be placed directly under the level 1 parent, instead it should be 50px to the left. I use a nested unordered list for the menu.

  • custom icon in "Places" menu

    - by Gurnarok
    Hi, I'm pretty new to Ubuntu, but I know the basics. I read the "How do I change the folder icons in the “Places” menu?" but it didn't help, did the option #2 since I want to specify it for a single directory (for now). So what should I do? I have the folder image as SVG in: /usr/share/icons/hicolor/scalable/apps/ /usr/share/icons/hicolor/scalable/places/ The image I want to use: and where I want it:

  • How to keep menu in a single place without using frames

    - by TJ Ellis
    This is probably a duplicate, but I can't find the answer anywhere (maybe I'm searching for the wrong thing?) and so I'm going to go ahead and ask. What is the accepted standard practice for creating a menu that is stored in a single file, but is included on every page across a site? Back in the day, one used frames, but this seems to be taboo now. I can get things layed out just the way I want, but copy/pasting across every page is a pain. I have seen php-based solutions, but my cheap-o free hosting doesn't support php (which is admittedly a pain, but it's a fairly simple webpage...). Any ideas for doing this that does not require server-side scripting?

  • Not able to create screenshot of when menu is active [closed]

    - by gotqn
    Possible Duplicate: Screenshot of active window doesn’t work I am using Ubuntu 12.04 and I am searching for a program that will let me to do screenshot of my menus too. Also, it will be very useful if I am able to "cut" only part of the new screenshot and save it as a new image. At this moment, when a menu is shown (for example I click on my clock and the calendar is shown) the "print screen" button is not working. This happens to with applications launchers menus in the left navigation panel. On windows I am using Gadwin Pro. Is there any alternative on Linux?

  • Can't boot into ubuntu 12.04, grub menu wont show

    - by Marcus
    Today i downloaded the ubunto 12.04 64bit and installed it on a 115gb partition next to a 15 gb swap alongside windows 7. (I have 2 drives. One with only windows (500gb) and another with a partition for (250gb) windows and (115gb) the ubunto and (15gb) swap partitions.) But after the installation i can't find out how to run ubuntu. It just run windows. I read that it should show a grub menu. i tried: Holding both shift keys at boot up. Running the cd-ubundu and edit the grub file. Also pressing the esc and some funtion button during boot. Nothing seems to work.

  • BAM Data Control in multiple ADF Faces Components

    - by [email protected]
    As we know Oracle BAM data control instance sharing is not supported.When two or more ADF Faces components must display the same data, and are bound to the same Oracle BAM data control definition, we have to make sure that we wrap each ADF Faces component in an ADF task flow, and set the Data Control Scope to isolated. This blog will show a small sample to demonstrate this. In this sample we will create a Pie and Bar using same BAM DC, such that both components use same Data control but have isolated scope.This sample can be downloaded  fromSample1.zip Set-up: Create a BAM data control using employees DO (sample) Steps: Right click on View Controller project and select "New->ADF Task Flow" Check "Create Bounded Task Flow" and give some meaningful name (ex:EmpPieTF.xml ) to the TaskFlow(TF) and click on "OK"CreateTF.bmpFrom the "Components Palette", drag and drop "View" into the task flow diagram. Give a meaningful name to the view. Double Click and Click "Ok" for  "Create New JSF Page Fragment" From "Data Controls" drag and drop "Employees->Query"  into this jsff page as "Graph->Pie" (Pie: Sales_Number and Slices: Salesperson) Repeat step 1 through 4 for another Task Flow (ex: EmpBarTF). From "Data Controls" drag and drop "Employees->Query"  into this jsff page as "Graph->Bar" (Bars :Sales_Number and X-axis : Salesperson). Open the Taskflow created in step 2. In the Structure Pane, right click on "Task Flow Definition -EmpPieTF" Click "Insert inside Task Flow Definition - EmpPieTF -> ADF Task Flow -> Data Control Scope". Click "OK"TFDCScope.bmpFor the "Data Control Scope", In the Property Inspector ->General section, change data control scope from Shared to Isolated. Repeat step 8 through 11 for the 2nd Task flow created. Now create a new jspx page example: Main.jspxDrag and drop both the Task flows (ex: "EmpPieTF" and "EmpBarTF") as regions. Surround with panel components as needed.Run the page Main.jspxMainPage.bmpNow when the page runs although both components are created using same Data control the bindings are not shared and each component will have a separate instance of the data control.

  • How do I underline parent menu item but not children?

    - by Steven
    Using Wordpress menu "builder", I get the following code: //Pseaudo code <ul id="main-menu-main"> <li class="menu-item"><a></a></li> <li class="menu-item current-menu-ancestor"> <a></a> <ul class="sub-menu"> <li class="menu-item"><a></a></li> <li class="menu-item current-menu-item"><a></a></li> </ul> </li> </ul> // and I use the following CSS #menu-main-menu a:hover { text-decoration: underline; } #menu-main-menu .current-menu-ancestor a { text-decoration: underline; } The problem with my last css line, is that all a elements under current-menu-ancestor are underlined. I only want the link in current-menu-ancestor to be underlined. I think this should be pretty simple, but right now my head is not focused :-/ The full code for parent / child looks like this: <ul id="menu-main-menu" class="menu"> <li id="menu-item-401" class="menu-item-first menu-item menu-item-type-post_type menu-item-object-page current-page-ancestor current-menu-ancestor current-menu-parent current-page-parent current_page_parent current_page_ancestor menu-item-401"> <a>menu 1</a> <ul class="sub-menu"> <li id="menu-item-444" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-415 current_page_item menu-item-444"> <a> sub 1</a> </li> </ul> </li>

  • Set item.selected in ASP.NET Menu Control

    - by BillB
    ASP.NET newbie here. When on a page I'd like to set the corresponding menu item to selected. My approach is this: On Home.aspx.cs: Menu menu = (Menu)Master.FindControl("Menu1"); if (menu.Items.Count > 0) { menu.FindItem("Home").Selected = true; } Trouble is, menu.item.count == 0. My menu is bound to a sitemap, if that matters. Thanks, Bill

  • Clean Up the New Ubuntu Grub2 Boot Menu

    - by Trevor Bekolay
    Ubuntu adopted the new version of the Grub boot manager in version 9.10, getting rid of the old problematic menu.lst. Today we look at how to change the boot menu options in Grub2. Grub2 is a step forward in a lot of ways, and most of the annoying menu.lst issues from the past are gone. Still, if you’re not vigilant with removing old versions of the kernel, the boot list can still end up being longer than it needs to be. Note: You may have to hold the SHIFT button on your keyboard while booting up to get this menu to show. If only one operating system is installed on your computer, it may load it automatically without displaying this menu. Remove Old Kernel Entries The most common clean up task for the boot menu is to remove old kernel versions lying around on your machine. In our case we want to remove the 2.6.32-21-generic boot menu entries. In the past, this meant opening up /boot/grub/menu.lst…but with Grub2, if we remove the kernel package from our computer, Grub automatically removes those options. To remove old kernel versions, open up Synaptic Package Manager, found in the System > Administration menu. When it opens up, type the kernel version that you want to remove in the Quick search text field. The first few numbers should suffice. For each of the entries associated with the old kernel (e.g. linux-headers-2.6.32-21 and linux-image-2.6.32-21-generic), right-click and choose Mark for Complete Removal. Click the Apply button in the toolbar and then Apply in the summary window that pops up. Close Synaptic Package Manager. The next time you boot up your computer, the Grub menu will not contain the entries associated with the removed kernel version. Remove Any Option by Editing /etc/grub.d If you need more fine-grained control, or want to remove entries that are not kernel versions, you must change the files located in /etc/grub.d. /etc/grub.d contains files that hold the menu entries that used to be contained in /boot/grub/menu.lst. If you want to add new boot menu entries, you would create a new file in this folder, making sure to mark it as executable. If you want to remove boot menu entries, as we do, you would edit files in this folder. If we wanted to remove all of the memtest86+ entries, we could just make the 20_memtest86+ file non-executable, with the terminal command sudo chmod –x 20_memtest86+ Followed by the terminal command sudo update-grub Note that memtest86+ was not found by update-grub because it will only consider executable files. However, instead, we’re going to remove the Serial console 115200 entry for memtest86+… Open a terminal window Applications > Accessories > Terminal. In the terminal window, type in the command: sudo gedit /etc/grub.d/20_memtest86+ The menu entries are found at the bottom of this file. Comment out the menu entry for serial console 115200 by adding a “#” to the start of each line. Save and close this file. In the terminal window you opened, enter in the command sudo update-grub Note: If you don’t run update-grub, the boot menu options will not change! Now, the next time you boot up, that strange entry will be gone, and you’re left with a simple and clean boot menu. Conclusion While changing Grub2’s boot menu may seem overly complicated to legacy Grub masters, for normal users, Grub2 means that you won’t have to change the boot menu that often. Fortunately, if you do have to do it, the process is still pretty easy. For more detailed information about how to change entries in Grub2, this Ubuntu forum thread is a great resource.

  • Windows 7 automatically rearranges the start menu

    - by Brice
    I've seen so many messages on how to rearrange the Windows Start Menu and none mentioning the real problem in doing so which has been around since XP at least. I go to ProgramData/Microsoft/Windows/Start Menu and have a day making everything the way I want. For one thing, their Maintenance menu, the Accessories menu and the Administrative Tools menu, I like to put under a Tools folder that I've created. And they seem to move OK. However, within a few hours, I see some of the shortcuts have been moved back or copied back and a new copy of these folders suddenly appears again on my Start Menu at the root. This is maddening and no one seems to even notice in all the tutorials I've read. Anyone know how to change this behavior?

  • A free standing ASP.NET Pager Web Control

    - by Rick Strahl
    Paging in ASP.NET has been relatively easy with stock controls supporting basic paging functionality. However, recently I built an MVC application and one of the things I ran into was that I HAD TO build manual paging support into a few of my pages. Dealing with list controls and rendering markup is easy enough, but doing paging is a little more involved. I ended up with a small but flexible component that can be dropped anywhere. As it turns out the task of creating a semi-generic Pager control for MVC was fairly easily. Now I’m back to working in Web Forms and thought to myself that the way I created the pager in MVC actually would also work in ASP.NET – in fact quite a bit easier since the whole thing can be conveniently wrapped up into an easily reusable control. A standalone pager would provider easier reuse in various pages and a more consistent pager display regardless of what kind of 'control’ the pager is associated with. Why a Pager Control? At first blush it might sound silly to create a new pager control – after all Web Forms has pretty decent paging support, doesn’t it? Well, sort of. Yes the GridView control has automatic paging built in and the ListView control has the related DataPager control. The built in ASP.NET paging has several issues though: Postback and JavaScript requirements If you look at paging links in ASP.NET they are always postback links with javascript:__doPostback() calls that go back to the server. While that works fine and actually has some benefit like the fact that paging saves changes to the page and post them back, it’s not very SEO friendly. Basically if you use javascript based navigation nosearch engine will follow the paging links which effectively cuts off list content on the first page. The DataPager control does support GET based links via the QueryStringParameter property, but the control is effectively tied to the ListView control (which is the only control that implements IPageableItemContainer). DataSource Controls required for Efficient Data Paging Retrieval The only way you can get paging to work efficiently where only the few records you display on the page are queried for and retrieved from the database you have to use a DataSource control - only the Linq and Entity DataSource controls  support this natively. While you can retrieve this data yourself manually, there’s no way to just assign the page number and render the pager based on this custom subset. Other than that default paging requires a full resultset for ASP.NET to filter the data and display only a subset which can be very resource intensive and wasteful if you’re dealing with largish resultsets (although I’m a firm believer in returning actually usable sets :-}). If you use your own business layer that doesn’t fit an ObjectDataSource you’re SOL. That’s a real shame too because with LINQ based querying it’s real easy to retrieve a subset of data that is just the data you want to display but the native Pager functionality doesn’t support just setting properties to display just the subset AFAIK. DataPager is not Free Standing The DataPager control is the closest thing to a decent Pager implementation that ASP.NET has, but alas it’s not a free standing component – it works off a related control and the only one that it effectively supports from the stock ASP.NET controls is the ListView control. This means you can’t use the same data pager formatting for a grid and a list view or vice versa and you’re always tied to the control. Paging Events In order to handle paging you have to deal with paging events. The events fire at specific time instances in the page pipeline and because of this you often have to handle data binding in a way to work around the paging events or else end up double binding your data sources based on paging. Yuk. Styling The GridView pager is a royal pain to beat into submission for styled rendering. The DataPager control has many more options and template layout and it renders somewhat cleaner, but it too is not exactly easy to get a decent display for. Not a Generic Solution The problem with the ASP.NET controls too is that it’s not generic. GridView, DataGrid use their own internal paging, ListView can use a DataPager and if you want to manually create data layout – well you’re on your own. IOW, depending on what you use you likely have very different looking Paging experiences. So, I figured I’ve struggled with this once too many and finally sat down and built a Pager control. The Pager Control My goal was to create a totally free standing control that has no dependencies on other controls and certainly no requirements for using DataSource controls. The idea is that you should be able to use this pager control without any sort of data requirements at all – you should just be able to set properties and be able to display a pager. The Pager control I ended up with has the following features: Completely free standing Pager control – no control or data dependencies Complete manual control – Pager can render without any data dependency Easy to use: Only need to set PageSize, ActivePage and TotalItems Supports optional filtering of IQueryable for efficient queries and Pager rendering Supports optional full set filtering of IEnumerable<T> and DataTable Page links are plain HTTP GET href Links Control automatically picks up Page links on the URL and assigns them (automatic page detection no page index changing events to hookup) Full CSS Styling support On the downside there’s no templating support for the control so the layout of the pager is relatively fixed. All elements however are stylable and there are options to control the text, and layout options such as whether to display first and last pages and the previous/next buttons and so on. To give you an idea what the pager looks like, here are two differently styled examples (all via CSS):   The markup for these two pagers looks like this: <ww:Pager runat="server" id="ItemPager" PageSize="5" PageLinkCssClass="gridpagerbutton" SelectedPageCssClass="gridpagerbutton-selected" PagesTextCssClass="gridpagertext" CssClass="gridpager" RenderContainerDiv="true" ContainerDivCssClass="gridpagercontainer" MaxPagesToDisplay="6" PagesText="Item Pages:" NextText="next" PreviousText="previous" /> <ww:Pager runat="server" id="ItemPager2" PageSize="5" RenderContainerDiv="true" MaxPagesToDisplay="6" /> The latter example uses default style settings so it there’s not much to set. The first example on the other hand explicitly assigns custom styles and overrides a few of the formatting options. Styling The styling is based on a number of CSS classes of which the the main pager, pagerbutton and pagerbutton-selected classes are the important ones. Other styles like pagerbutton-next/prev/first/last are based on the pagerbutton style. The default styling shown for the red outlined pager looks like this: .pagercontainer { margin: 20px 0; background: whitesmoke; padding: 5px; } .pager { float: right; font-size: 10pt; text-align: left; } .pagerbutton,.pagerbutton-selected,.pagertext { display: block; float: left; text-align: center; border: solid 2px maroon; min-width: 18px; margin-left: 3px; text-decoration: none; padding: 4px; } .pagerbutton-selected { font-size: 130%; font-weight: bold; color: maroon; border-width: 0px; background: khaki; } .pagerbutton-first { margin-right: 12px; } .pagerbutton-last,.pagerbutton-prev { margin-left: 12px; } .pagertext { border: none; margin-left: 30px; font-weight: bold; } .pagerbutton a { text-decoration: none; } .pagerbutton:hover { background-color: maroon; color: cornsilk; } .pagerbutton-prev { background-image: url(images/prev.png); background-position: 2px center; background-repeat: no-repeat; width: 35px; padding-left: 20px; } .pagerbutton-next { background-image: url(images/next.png); background-position: 40px center; background-repeat: no-repeat; width: 35px; padding-right: 20px; margin-right: 0px; } Yup that’s a lot of styling settings although not all of them are required. The key ones are pagerbutton, pager and pager selection. The others (which are implicitly created by the control based on the pagerbutton style) are for custom markup of the ‘special’ buttons. In my apps I tend to have two kinds of pages: Those that are associated with typical ‘grid’ displays that display purely tabular data and those that have a more looser list like layout. The two pagers shown above represent these two views and the pager and gridpager styles in my standard style sheet reflect these two styles. Configuring the Pager with Code Finally lets look at what it takes to hook up the pager. As mentioned in the highlights the Pager control is completely independent of other controls so if you just want to display a pager on its own it’s as simple as dropping the control and assigning the PageSize, ActivePage and either TotalPages or TotalItems. So for this markup: <ww:Pager runat="server" id="ItemPagerManual" PageSize="5" MaxPagesToDisplay="6" /> I can use code as simple as: ItemPagerManual.PageSize = 3; ItemPagerManual.ActivePage = 4;ItemPagerManual.TotalItems = 20; Note that ActivePage is not required - it will automatically use any Page=x query string value and assign it, although you can override it as I did above. TotalItems can be any value that you retrieve from a result set or manually assign as I did above. A more realistic scenario based on a LINQ to SQL IQueryable result is even easier. In this example, I have a UserControl that contains a ListView control that renders IQueryable data. I use a User Control here because there are different views the user can choose from with each view being a different user control. This incidentally also highlights one of the nice features of the pager: Because the pager is independent of the control I can put the pager on the host page instead of into each of the user controls. IOW, there’s only one Pager control, but there are potentially many user controls/listviews that hold the actual display data. The following code demonstrates how to use the Pager with an IQueryable that loads only the records it displays: protected voidPage_Load(objectsender, EventArgs e) {     Category = Request.Params["Category"] ?? string.Empty;     IQueryable<wws_Item> ItemList = ItemRepository.GetItemsByCategory(Category);     // Update the page and filter the list down     ItemList = ItemPager.FilterIQueryable<wws_Item>(ItemList); // Render user control with a list view Control ulItemList = LoadControl("~/usercontrols/" + App.Configuration.ItemListType + ".ascx"); ((IInventoryItemListControl)ulItemList).InventoryItemList = ItemList; phItemList.Controls.Add(ulItemList); // placeholder } The code uses a business object to retrieve Items by category as an IQueryable which means that the result is only an expression tree that hasn’t execute SQL yet and can be further filtered. I then pass this IQueryable to the FilterIQueryable() helper method of the control which does two main things: Filters the IQueryable to retrieve only the data displayed on the active page Sets the Totaltems property and calculates TotalPages on the Pager and that’s it! When the Pager renders it uses those values, plus the PageSize and ActivePage properties to render the Pager. In addition to IQueryable there are also filter methods for IEnumerable<T> and DataTable, but these versions just filter the data by removing rows/items from the entire already retrieved data. Output Generated and Paging Links The output generated creates pager links as plain href links. Here’s what the output looks like: <div id="ItemPager" class="pagercontainer"> <div class="pager"> <span class="pagertext">Pages: </span><a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=1" class="pagerbutton" />1</a> <a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=2" class="pagerbutton" />2</a> <a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=3" class="pagerbutton" />3</a> <span class="pagerbutton-selected">4</span> <a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=5" class="pagerbutton" />5</a> <a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=6" class="pagerbutton" />6</a> <a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=20" class="pagerbutton pagerbutton-last" />20</a>&nbsp;<a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=3" class="pagerbutton pagerbutton-prev" />Prev</a>&nbsp;<a href="http://localhost/WestWindWebStore/itemlist.aspx?Page=5" class="pagerbutton pagerbutton-next" />Next</a></div> <br clear="all" /> </div> </div> The links point back to the current page and simply append a Page= page link into the page. When the page gets reloaded with the new page number the pager automatically detects the page number and automatically assigns the ActivePage property which results in the appropriate page to be displayed. The code shown in the previous section is all that’s needed to handle paging. Note that HTTP GET based paging is different than the Postback paging ASP.NET uses by default. Postback paging preserves modified page content when clicking on pager buttons, but this control will simply load a new page – no page preservation at this time. The advantage of not using Postback paging is that the URLs generated are plain HTML links that a search engine can follow where __doPostback() links are not. Pager with a Grid The pager also works in combination with grid controls so it’s easy to bypass the grid control’s paging features if desired. In the following example I use a gridView control and binds it to a DataTable result which is also filterable by the Pager control. The very basic plain vanilla ASP.NET grid markup looks like this: <div style="width: 600px; margin: 0 auto;padding: 20px; "> <asp:DataGrid runat="server" AutoGenerateColumns="True" ID="gdItems" CssClass="blackborder" style="width: 600px;"> <AlternatingItemStyle CssClass="gridalternate" /> <HeaderStyle CssClass="gridheader" /> </asp:DataGrid> <ww:Pager runat="server" ID="Pager" CssClass="gridpager" ContainerDivCssClass="gridpagercontainer" PageLinkCssClass="gridpagerbutton" SelectedPageCssClass="gridpagerbutton-selected" PageSize="8" RenderContainerDiv="true" MaxPagesToDisplay="6" /> </div> and looks like this when rendered: using custom set of CSS styles. The code behind for this code is also very simple: protected void Page_Load(object sender, EventArgs e) { string category = Request.Params["category"] ?? ""; busItem itemRep = WebStoreFactory.GetItem(); var items = itemRep.GetItemsByCategory(category) .Select(itm => new {Sku = itm.Sku, Description = itm.Description}); // run query into a DataTable for demonstration DataTable dt = itemRep.Converter.ToDataTable(items,"TItems"); // Remove all items not on the current page dt = Pager.FilterDataTable(dt,0); // bind and display gdItems.DataSource = dt; gdItems.DataBind(); } A little contrived I suppose since the list could already be bound from the list of elements, but this is to demonstrate that you can also bind against a DataTable if your business layer returns those. Unfortunately there’s no way to filter a DataReader as it’s a one way forward only reader and the reader is required by the DataSource to perform the bindings.  However, you can still use a DataReader as long as your business logic filters the data prior to rendering and provides a total item count (most likely as a second query). Control Creation The control itself is a pretty brute force ASP.NET control. Nothing clever about this other than some basic rendering logic and some simple calculations and update routines to determine which buttons need to be shown. You can take a look at the full code from the West Wind Web Toolkit’s Repository (note there are a few dependencies). To give you an idea how the control works here is the Render() method: /// <summary> /// overridden to handle custom pager rendering for runtime and design time /// </summary> /// <param name="writer"></param> protected override void Render(HtmlTextWriter writer) { base.Render(writer); if (TotalPages == 0 && TotalItems > 0) TotalPages = CalculateTotalPagesFromTotalItems(); if (DesignMode) TotalPages = 10; // don't render pager if there's only one page if (TotalPages < 2) return; if (RenderContainerDiv) { if (!string.IsNullOrEmpty(ContainerDivCssClass)) writer.AddAttribute("class", ContainerDivCssClass); writer.RenderBeginTag("div"); } // main pager wrapper writer.WriteBeginTag("div"); writer.AddAttribute("id", this.ClientID); if (!string.IsNullOrEmpty(CssClass)) writer.WriteAttribute("class", this.CssClass); writer.Write(HtmlTextWriter.TagRightChar + "\r\n"); // Pages Text writer.WriteBeginTag("span"); if (!string.IsNullOrEmpty(PagesTextCssClass)) writer.WriteAttribute("class", PagesTextCssClass); writer.Write(HtmlTextWriter.TagRightChar); writer.Write(this.PagesText); writer.WriteEndTag("span"); // if the base url is empty use the current URL FixupBaseUrl(); // set _startPage and _endPage ConfigurePagesToRender(); // write out first page link if (ShowFirstAndLastPageLinks && _startPage != 1) { writer.WriteBeginTag("a"); string pageUrl = StringUtils.SetUrlEncodedKey(BaseUrl, QueryStringPageField, (1).ToString()); writer.WriteAttribute("href", pageUrl); if (!string.IsNullOrEmpty(PageLinkCssClass)) writer.WriteAttribute("class", PageLinkCssClass + " " + PageLinkCssClass + "-first"); writer.Write(HtmlTextWriter.SelfClosingTagEnd); writer.Write("1"); writer.WriteEndTag("a"); writer.Write("&nbsp;"); } // write out all the page links for (int i = _startPage; i < _endPage + 1; i++) { if (i == ActivePage) { writer.WriteBeginTag("span"); if (!string.IsNullOrEmpty(SelectedPageCssClass)) writer.WriteAttribute("class", SelectedPageCssClass); writer.Write(HtmlTextWriter.TagRightChar); writer.Write(i.ToString()); writer.WriteEndTag("span"); } else { writer.WriteBeginTag("a"); string pageUrl = StringUtils.SetUrlEncodedKey(BaseUrl, QueryStringPageField, i.ToString()).TrimEnd('&'); writer.WriteAttribute("href", pageUrl); if (!string.IsNullOrEmpty(PageLinkCssClass)) writer.WriteAttribute("class", PageLinkCssClass); writer.Write(HtmlTextWriter.SelfClosingTagEnd); writer.Write(i.ToString()); writer.WriteEndTag("a"); } writer.Write("\r\n"); } // write out last page link if (ShowFirstAndLastPageLinks && _endPage < TotalPages) { writer.WriteBeginTag("a"); string pageUrl = StringUtils.SetUrlEncodedKey(BaseUrl, QueryStringPageField, TotalPages.ToString()); writer.WriteAttribute("href", pageUrl); if (!string.IsNullOrEmpty(PageLinkCssClass)) writer.WriteAttribute("class", PageLinkCssClass + " " + PageLinkCssClass + "-last"); writer.Write(HtmlTextWriter.SelfClosingTagEnd); writer.Write(TotalPages.ToString()); writer.WriteEndTag("a"); } // Previous link if (ShowPreviousNextLinks && !string.IsNullOrEmpty(PreviousText) && ActivePage > 1) { writer.Write("&nbsp;"); writer.WriteBeginTag("a"); string pageUrl = StringUtils.SetUrlEncodedKey(BaseUrl, QueryStringPageField, (ActivePage - 1).ToString()); writer.WriteAttribute("href", pageUrl); if (!string.IsNullOrEmpty(PageLinkCssClass)) writer.WriteAttribute("class", PageLinkCssClass + " " + PageLinkCssClass + "-prev"); writer.Write(HtmlTextWriter.SelfClosingTagEnd); writer.Write(PreviousText); writer.WriteEndTag("a"); } // Next link if (ShowPreviousNextLinks && !string.IsNullOrEmpty(NextText) && ActivePage < TotalPages) { writer.Write("&nbsp;"); writer.WriteBeginTag("a"); string pageUrl = StringUtils.SetUrlEncodedKey(BaseUrl, QueryStringPageField, (ActivePage + 1).ToString()); writer.WriteAttribute("href", pageUrl); if (!string.IsNullOrEmpty(PageLinkCssClass)) writer.WriteAttribute("class", PageLinkCssClass + " " + PageLinkCssClass + "-next"); writer.Write(HtmlTextWriter.SelfClosingTagEnd); writer.Write(NextText); writer.WriteEndTag("a"); } writer.WriteEndTag("div"); if (RenderContainerDiv) { if (RenderContainerDivBreak) writer.Write("<br clear=\"all\" />\r\n"); writer.WriteEndTag("div"); } } As I said pretty much brute force rendering based on the control’s property settings of which there are quite a few: You can also see the pager in the designer above. unfortunately the VS designer (both 2010 and 2008) fails to render the float: left CSS styles properly and starts wrapping after margins are applied in the special buttons. Not a big deal since VS does at least respect the spacing (the floated elements overlay). Then again I’m not using the designer anyway :-}. Filtering Data What makes the Pager easy to use is the filter methods built into the control. While this functionality is clearly not the most politically correct design choice as it violates separation of concerns, it’s very useful for typical pager operation. While I actually have filter methods that do something similar in my business layer, having it exposed on the control makes the control a lot more useful for typical databinding scenarios. Of course these methods are optional – if you have a business layer that can provide filtered page queries for you can use that instead and assign the TotalItems property manually. There are three filter method types available for IQueryable, IEnumerable and for DataTable which tend to be the most common use cases in my apps old and new. The IQueryable version is pretty simple as it can simply rely on on .Skip() and .Take() with LINQ: /// <summary> /// <summary> /// Queries the database for the ActivePage applied manually /// or from the Request["page"] variable. This routine /// figures out and sets TotalPages, ActivePage and /// returns a filtered subset IQueryable that contains /// only the items from the ActivePage. /// </summary> /// <param name="query"></param> /// <param name="activePage"> /// The page you want to display. Sets the ActivePage property when passed. /// Pass 0 or smaller to use ActivePage setting. /// </param> /// <returns></returns> public IQueryable<T> FilterIQueryable<T>(IQueryable<T> query, int activePage) where T : class, new() { ActivePage = activePage < 1 ? ActivePage : activePage; if (ActivePage < 1) ActivePage = 1; TotalItems = query.Count(); if (TotalItems <= PageSize) { ActivePage = 1; TotalPages = 1; return query; } int skip = ActivePage - 1; if (skip > 0) query = query.Skip(skip * PageSize); _TotalPages = CalculateTotalPagesFromTotalItems(); return query.Take(PageSize); } The IEnumerable<T> version simply  converts the IEnumerable to an IQuerable and calls back into this method for filtering. The DataTable version requires a little more work to manually parse and filter records (I didn’t want to add the Linq DataSetExtensions assembly just for this): /// <summary> /// Filters a data table for an ActivePage. /// /// Note: Modifies the data set permanently by remove DataRows /// </summary> /// <param name="dt">Full result DataTable</param> /// <param name="activePage">Page to display. 0 to use ActivePage property </param> /// <returns></returns> public DataTable FilterDataTable(DataTable dt, int activePage) { ActivePage = activePage < 1 ? ActivePage : activePage; if (ActivePage < 1) ActivePage = 1; TotalItems = dt.Rows.Count; if (TotalItems <= PageSize) { ActivePage = 1; TotalPages = 1; return dt; } int skip = ActivePage - 1; if (skip > 0) { for (int i = 0; i < skip * PageSize; i++ ) dt.Rows.RemoveAt(0); } while(dt.Rows.Count > PageSize) dt.Rows.RemoveAt(PageSize); return dt; } Using the Pager Control The pager as it is is a first cut I built a couple of weeks ago and since then have been tweaking a little as part of an internal project I’m working on. I’ve replaced a bunch of pagers on various older pages with this pager without any issues and have what now feels like a more consistent user interface where paging looks and feels the same across different controls. As a bonus I’m only loading the data from the database that I need to display a single page. With the preset class tags applied too adding a pager is now as easy as dropping the control and adding the style sheet for styling to be consistent – no fuss, no muss. Schweet. Hopefully some of you may find this as useful as I have or at least as a baseline to build ontop of… Resources The Pager is part of the West Wind Web & Ajax Toolkit Pager.cs Source Code (some toolkit dependencies) Westwind.css base stylesheet with .pager and .gridpager styles Pager Example Page © Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

    Hello, I am creating a menu and binding the menu items ate runtime as follows but I am not able to make it work. I am creating the menu as follows: Menu menu = new Menu(); menu.Items.Add(new MenuItem { Command = new PackCommand(), Header = "Pack" }); DockPanel.SetDock(menu, Dock.Top); content.Children.Add(menu); And I am implementing ICommand: public static class PackCommand : ICommand { Boolean CanExecute(object parameter) { return true; } void Execute(object parameter) { Packer packer = new Packer(); packer.Run(); } } I am not sure how to bind the menu item. Why CanExecute? Shouldn't it always? I only want to run packer.Run when the buttom is clicked. I think I should implement ICommand but I am not even sure I should do this?

  • Ajax Control Toolkit December 2013 Release

    - by Stephen.Walther
    Today, we released a new version of the Ajax Control Toolkit that contains several important bug fixes and new features. The new release contains a new Tabs control that has been entirely rewritten in jQuery. You can download the December 2013 release of the Ajax Control Toolkit at http://Ajax.CodePlex.com. Alternatively, you can install the latest version directly from NuGet: The Ajax Control Toolkit and jQuery The Ajax Control Toolkit now contains two controls written with jQuery: the ToggleButton control and the Tabs control.  The goal is to rewrite the Ajax Control Toolkit to use jQuery instead of the Microsoft Ajax Library gradually over time. The motivation for rewriting the controls in the Ajax Control Toolkit to use jQuery is to modernize the toolkit. We want to continue to accept new controls written for the Ajax Control Toolkit contributed by the community. The community wants to use jQuery. We want to make it easy for the community to submit bug fixes. The community understands jQuery. Using the Ajax Control Toolkit with a Website that Already uses jQuery But what if you are already using jQuery in your website?  Will adding the Ajax Control Toolkit to your website break your existing website?  No, and here is why. The Ajax Control Toolkit uses jQuery.noConflict() to avoid conflicting with an existing version of jQuery in a page.  The version of jQuery that the Ajax Control Toolkit uses is represented by a variable named actJQuery.  You can use actJQuery side-by-side with an existing version of jQuery in a page without conflict.Imagine, for example, that you add jQuery to an ASP.NET page using a <script> tag like this: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="TestACTDec2013.WebForm1" %> <!DOCTYPE html> <html > <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <script src="Scripts/jquery-2.0.3.min.js"></script> <ajaxToolkit:ToolkitScriptManager runat="server" /> <ajaxToolkit:TabContainer runat="server"> <ajaxToolkit:TabPanel runat="server"> <HeaderTemplate> Tab 1 </HeaderTemplate> <ContentTemplate> <h1>First Tab</h1> </ContentTemplate> </ajaxToolkit:TabPanel> <ajaxToolkit:TabPanel runat="server"> <HeaderTemplate> Tab 2 </HeaderTemplate> <ContentTemplate> <h1>Second Tab</h1> </ContentTemplate> </ajaxToolkit:TabPanel> </ajaxToolkit:TabContainer> </div> </form> </body> </html> The page above uses the Ajax Control Toolkit Tabs control (TabContainer and TabPanel controls).  The Tabs control uses the version of jQuery that is currently bundled with the Ajax Control Toolkit (jQuery version 1.9.1). The page above also includes a <script> tag that references jQuery version 2.0.3.  You might need that particular version of jQuery, for example, to use a particular jQuery plugin. The two versions of jQuery in the page do not create a conflict. This fact can be demonstrated by entering the following two commands in the JavaScript console window: actJQuery.fn.jquery $.fn.jquery Typing actJQuery.fn.jquery will display the version of jQuery used by the Ajax Control Toolkit and typing $.fn.jquery (or jQuery.fn.jquery) will show the version of jQuery used by other jQuery plugins in the page.      Preventing jQuery from Loading Twice So by default, the Ajax Control Toolkit will not conflict with any existing version of jQuery used in your application. However, this does mean that if you are already using jQuery in your application then jQuery will be loaded twice. For performance reasons, you might want to avoid loading the jQuery library twice. By taking advantage of the <remove> element in the AjaxControlToolkit.config file, you can prevent the Ajax Control Toolkit from loading its version of jQuery. <ajaxControlToolkit> <scripts> <remove name="jQuery.jQuery.js" /> </scripts> <controlBundles> <controlBundle> <control name="TabContainer" /> <control name="TabPanel" /> </controlBundle> </controlBundles> </ajaxControlToolkit> Be careful here:  the name of the script being removed – jQuery.jQuery.js – is case-sensitive. If you remove jQuery then it is your responsibility to add the exact same version of jQuery back into your application.  You can add jQuery back using a <script> tag like this: <script src="Scripts/jquery-1.9.1.min.js"></script>     Make sure that you add the <script> tag before the server-side <form> tag or the Ajax Control Toolkit won’t detect the presence of jQuery. Alternatively, you can use the ToolkitScriptManager like this: <ajaxToolkit:ToolkitScriptManager runat="server"> <Scripts> <asp:ScriptReference Name="jQuery.jQuery.js" /> </Scripts> </ajaxToolkit:ToolkitScriptManager> The Ajax Control Toolkit is tested against the particular version of jQuery that is bundled with the Ajax Control Toolkit. Currently, the Ajax Control Toolkit uses jQuery version 1.9.1. If you attempt to use a different version of jQuery with the Ajax Control Toolkit then you will get the exception jQuery 1.9.1 is required in your JavaScript console window: If you need to use a different version of jQuery in the same page as the Ajax Control Toolkit then you should not use the <remove> element. Instead, allow the Ajax Control Toolkit to load its version of jQuery side-by-side with the other version of jQuery. Lots of Bug Fixes As usual, we implemented several important bug fixes with this release. The bug fixes concerned the following three controls: Tabs control – In the course of rewriting the Tabs control to use jQuery, we fixed several bugs related to the Tabs control. AjaxFileUpload control – We resolved an issue concerning the AjaxFileUpload and the TMP directory. HTMLEditor control – We updated the HTMLEditor control to use the new Ajax Control Toolkit bundling and minification framework. Summary I would like to thank the Superexpert team for their hard work on this release. Many long hours of coding and testing went into making this release possible.

  • How can menu bars that require a right click be activated?

    - by Amos Annoy
    I've noticed that NetworkManager only has a single, left or right, click menu and no longer has an About menu option to show it's splash screen. In fact all the top bar mini short cut icons have been amputated and crippled leaving them with no rights. This severely impacts on our custom aps., similar to FireFox bookmarks, which can no longer be right clicked to bring up a context menu. It is possible to disengage FF's File|Edit|... menu bar from the top by running it in safe-mode so the menu bar is resident in a window, restoring right clicks, but our aps. do not have "safe modes".

  • Control to Control Binding in WPF/Silverlight

    - by psheriff
    In the past if you had two controls that you needed to work together, you would have to write code. For example, if you want a label control to display any text a user typed into a text box you would write code to do that. If you want turn off a set of controls when a user checks a check box, you would also have to write code. However, with XAML, these operations become very easy to do. Bind Text Box to Text Block As a basic example of this functionality, let’s bind a TextBlock control to a TextBox. When the user types into a TextBox the value typed in will show up in the TextBlock control as well. To try this out, create a new Silverlight or WPF application in Visual Studio. On the main window or user control type in the following XAML. <StackPanel>  <TextBox Margin="10" x:Name="txtData" />  <TextBlock Margin="10"              Text="{Binding ElementName=txtData,                             Path=Text}" /></StackPanel> Now run the application and type into the TextBox control. As you type you will see the data you type also appear in the TextBlock control. The {Binding} markup extension is responsible for this behavior. You set the ElementName attribute of the Binding markup to the name of the control that you wish to bind to. You then set the Path attribute to the name of the property of that control you wish to bind to. That’s all there is to it! Bind the IsEnabled Property Now let’s apply this concept to something that you might use in a business application. Consider the following two screen shots. The idea is that if the Add Benefits check box is un-checked, then the IsEnabled property of the three “Benefits” check boxes will be set to false (Figure 1). If the Add Benefits check box is checked, then the IsEnabled property of the “Benefits” check boxes will be set to true (Figure 2). Figure 1: Uncheck Add Benefits and the Benefits will be disabled. Figure 2: Check Add Benefits and the Benefits will be enabled. To accomplish this, you would write XAML to bind to each of the check boxes in the “Benefits To Add” section to the check box named chkBenefits. Below is a fragment of the XAML code that would be used. <CheckBox x:Name="chkBenefits" /> <CheckBox Content="401k"           IsEnabled="{Binding ElementName=chkBenefits,                               Path=IsChecked}" /> Since the IsEnabled property is a boolean type and the IsChecked property is also a boolean type, you can bind these two together. If they were different types, or if you needed them to set the IsEnabled property to the inverse of the IsChecked property then you would need to use a ValueConverter class. SummaryOnce you understand the basics of data binding in XAML, you can eliminate a lot code. Connecting controls together is as easy as just setting the ElementName and Path properties of the Binding markup extension.
