  • dynamic GridView in CreateChildControls throws a "RegisterRequiresControlState can only be called be

    - by tbischel
    I am trying to add a GridView dynamically to a SharePoint Web Part. Right now, the first time I load the gridview, everything works fine. My gridview has an edit column enabled... so when I click that, it throws an exception when I try and add the gridview control on the postback. The exception: "RegisterRequiresControlState can only be called before and during PreRender" I've tried adding my controls in the CreateChildControls function, the OnInit, OnPageLoad, and OnPreRender... all exhibit the same problem. Does anyone know what might cause this kind of error? Edit: So to test this problem, I created a local GridView in the webpart, recreating all the properties in the one that failed. It actually worked this time through... the only difference that I could identify was that I had made the gridview a static variable in another class, where as here I initiated the gridview as a local variable. I even used the same initializing function for both the original and modified version, same difference. So why would creating a GridView locally affect the ability to add it to a web part?

  • CSS window height problem with dynamic loaded css

    - by Michael Mao
    Hi all: Please go here and use username "admin" and password "endlesscomic" (without wrapper quotes) to see the web app demo. Basically what I am trying to do is to incrementally integrate my work to this web app, say, every nightly, for the client to check the progress. Also, he would like to see, at the very beginning, a mockup about the page layout. I am trying to use the 960 grid system to achieve this. So far, so good. Except one issue that when the "mockup.css" is loaded dynamically by jQuery, it "extends" the window to the bottom, something I do not wanna have... As an inexperienced web developer, I don't know which part is wrong. Below is my js: /* master.js */ $(document).ready(function() { $('#addDebugCss').click(function() { alertMessage('adding debug css...'); addCssToHead('./css/debug.css'); $('.grid-insider').css('opacity','0.5');//reset mockup background transparcy }); $('#addMockupCss').click(function() { alertMessage('adding mockup css...'); addCssToHead('./css/mockup.css'); $('.grid-insider').css('opacity','1');//set semi-background transparcy for mockup }); $('#resetCss').click(function() { alertMessage('rolling back to normal'); rollbackCss(new Array("./css/mockup.css", "./css/debug.css")); }); }); function alertMessage(msg) //TODO find a better modal prompt { alert(msg); } function addCssToHead(path_to_css) { $('<link rel="stylesheet" type="text/css" href="' + path_to_css + '" />').appendTo("head"); } function rollbackCss(set) { for(var i in set) { $('link[href="'+ set[i]+ '"]').remove(); } } Something should be added to the exteral mockup.css? Or something to change in my master.js? Thanks for any hints/suggestions in advance.

  • dynamic ContextMenu in TreeView vs. MVVM

    - by bitbonk
    I have a tree of ViewModels displayed as a TreeView (using HierarchicalDataTemplate). Each ViewModel instance has different commands that can be executed on it wich again are exposed as a list of command ViewModels for each item ViewModel. How can I create a single ContextMenu that opens at the TreeViewItem that was rightclicked and that populates its commands from the underlying item ViewModel's command ViewModels list? All in a decent MVVM fashion ...

  • Dynamic Colorbox galleries using Ajax

    - by Gobitron
    Hi, I am new to jQuery / AJAX. I have a page that uses colorbox to display photo galleries. The page displays only one image from each gallery. When clicked, a colorbox opens up with all of the photos from that gallery. These inner photo references (for all photos from all galleries) are hidden on the page in an invisible div. The page is a PHP generated page. The galleries/photos are being populated via Picasa. All of the above works fine, but instead of loading all of the images from all galleries on page load (via PHP), I'd like to load only the requested gallery into the colorbox via AJAX. So far, I have a test page which can insert the proper links into a div on the page, but the Colorbox won't pick up on these links. This is where I need help. How can I get Colorbox to recognize the links generated by my AJAX call? The colorbox scripts sit in the header: <script type="text/javascript" src="libs/js/jquery.colorbox.js"></script> <script type="text/javascript"> //Writing out the ColorBox command for each album $(document).ready(function(){ <?php $setnum = 0; foreach ($albumIds as $albumId){ echo "\t\t\t$(\"a[rel='set" . $setnum . "']\").colorbox({maxWidth:\"640px\", maxHeight:\"480px\"});\n"; $setnum++; } ?> }); </script> Here is my get JSON code located in the body section of the page: $.getJSON("myserv.php",formContent, function(json){ var photos = json.data.items; var numpics = json.data.items.length; var pointer = 1; while (pointer < numpics){ var stuffineed = photos[pointer].media.image.url; $("#ajaxBox").append("<a href='" + stuffineed + "' rel='set" + pointer +"'>" + photos[pointer].media.image.url + "</a><br />"); pointer++; } }); //End json Again, I can get the AJAX to populate the div correctly, but the colorbox script isn't picking up these images. Any help would be greatly appreciated.

  • Notification Email Best Practices--From Server Setup to Programming

    - by Andrew Wagner
    All, I'm in the process now of building a SaaS tool that allows network admins to generate notification emails to the members of the end-users of our platform (among many many other things). I'm running into a bit of an "out of my expertise" wall, as I know there are a lot of variables involved with configuring an application that can: Run in a distributed way via load balancing and still-- Leverage a single mail server for sending notification emails Process unsubscribe requests Avoid any ISP blacklisting in the process. If anyone has the time and has done this before, I'd love if you could walk me through the A-Z of best practices both from a configuration perspective and an execution perspective for generating these emails (anything from necessary DNS settings to ideal SMTP setup and configuration) Currently, our application generates email via Google Apps using the PHPMailer class. While this works well, it doesn't queue messages (potential for timeout problems if any of our clients amass a very large list of end-users), and Google limits the amount of allowed generated email messages to 500/day. I know this is a lofty question, but any guidance you could provide would be smashing and a big help as we work through this hurtle in our beta development stage. Thanks!

    - by Antonio Murgia
    My app has to load an image from a http server and displaying it into an UIImageView How can i do that?? I tried this: NSString *temp = [NSString alloc]; [temp stringwithString:@"http://192.168.1.2x0/pic/LC.jpg"] temp=[(NSString *)CFURLCreateStringByAddingPercentEscapes( nil, (CFStringRef)temp, NULL, NULL, kCFStringEncodingUTF8) autorelease]; NSData *dato = [NSData alloc]; dato=[NSData dataWithContentsOfURL:[NSURL URLWithString:temp]]; pic = [pic initWithImage:[UIImage imageWithData:dato]]; This code is in viewdidload of the view but nothing is displayed! The server is working because i can load xml files from it. but i can't display that image! I need to load the image programmatically because it has to change depending on the parameter passed! Thank you in advance. Antonio

  • Cygwin socket & thread & other programming issues (some question about Cygwin)

    - by SjB
    I have some question about cygwin : Can I use Cygwin develop socket based code? Does Cygwin have read() and write() functions that work with file descriptors? Can I use Pthread library in Cygwin? Does code that compiles in Cygwin also compile in Linux without any change or with little change? Will an executable file that built by Cygwin run in Linux ? Why does Cygwin not need the linker option -lpthread when I use pthread library? why in #include <iostream> don't I need to use using namespace std; ? Can I work with QT in Cygwin? If so, How?

  • jQuery: Dynamic image handling (waiting for load)

    - by dclowd9901
    I'm trying to write a plugin that has a built in function to wait until all images that are on the page to be loaded before it executes itself. $(window).load() only works if it's the initial load of the page, but if someone wants to pull down some HTML through AJAX that contains images, it doesn't work. Is there any good way of doing this AND implementing it so that it can be self-contained in the plug-in? I've tried looping over $('img').complete, and I know that doesn't work (the images never load, and the browser crashes under a "script takes too long to complete" bug). For an example of what I'm trying to do, visit the page I'm looking to house the plugin at: http://www.simplesli.de If you go to the "more uses" section (click it on the nav bar), you'll see that the image slideshow won't load properly. I know the current code doesn't work, but it's just holding place until I figure something out.

  • How to fix notifyDataSetChanged/ListView problems in dynamic Adapter wrapper Android

    - by ipaterson
    Summary: Trying to dynamically add heading rows to a ListView via a custom adapter wrapper. ListView is having trouble keeping the scroll position in sync. Runnable demo project provided. I would like to dynamically add items to a list based on the values in a CursorAdapter, several positions ahead of what the user is currently viewing. To do this, I have an adapter that wraps the CursorAdapter and keeps the new content indexed in a SparseArray. The ListView needs to be updated when items are added to the custom adapter, but I have met a lot of pitfalls trying to get that to work and would love some advice. The demo project can be downloaded here: http://dl.dropbox.com/u/15334423/DynamicSectionedList.zip In the demo, the headings are added dynamically by looking ahead 10 places to find the correct position where the list items switch to the next letter. Each implementation of notifyDataSetChanged has problems as described: Demo 1 This demo shows the importance of notifyDataSetChanged(). On clicking anything, the app will crash. This is due to some sanity checking in ListView... mItemCount != adapter.getItemCount(). Moral is, we need to notify the list that data has changed. Demo 2 The natural next step is to notify the ListView of changes when changes occur. Unfortunately, doing so while the ListView is scrolling firmly breaks all touch interaction until the app switches out of touch mode. You will need to "fling scroll" far enough to generate new headings in order to notice this. Tapping the screen will not cause the scroll to stop, and once stopped none of the list items will be clickable. This is due to some if (!mDataChanged) { /* do very important stuff */ } code in AbsListView.onTouchEvent(). Demo 3 To fix this, Demo 3 introduces a pendingChanges flag and the custom Adapter gains a notifyDataSetChangedIfNeeded() which can be called by the ListView once it has entered a "safe" state for changes. The first point where changes must be notified is in ListView.layoutChildren(), so I overrode that method to first notify of changes if needed, then call through. Fling past at least one heading then click a list item. This doesn't quite work right, though I'm not totally sure why. Tapping or selecting an item with the keyboard/trackball causes the list to refresh without properly syncing the old position. It scrolls to the top of the list which is not acceptable. Demo 4 The scroll problem in Demo 3 can be conquered, at least in touch mode. By adding a call to notifyDataSetChangedIfNeeded() on touch down, the data change happens to take place at such a time that all touch interaction works as expected and the list position is properly synced. However, I can't find an analog for that when the device is not in touch mode, not to mention the fact that it definitely seems like a hack. The list almost always scrolls back to the top, I can't find out what causes it to occasionally maintain the correct position. Since Android is fighting me at each step of the way, I feel like there should be a better approach. Please try the demo, if any fixes can be applied to get it working that would be great! Many thanks to anyone who can look into this, hopefully if we can get the code working it will be useful for others trying to accomplish the same optimization for lists with headings.

  • Kohana 3: How to find the active item in a dynamic menu

    - by Svish
    Maybe not the best explanation, but hear me out. Say I have the following in a config file called menu.php: // Default controller is 'home' and default action is 'index' return array( 'items' => array( 'Home' => '', 'News' => 'news', 'Resources' => 'resources', ), ); I now want to print this out as a menu, which is pretty simple: foreach(Kohana::config('menu.items') as $title => $uri) { echo '<li>' . HTML::anchor($uri, $title) . '</li>'; } However, I want to find the $uri that matches the current controller and action. And if the action is the default one or not. What I want to end up with is that menu item should have id="active-item" if it is the linking to the current controller, but the default action. And id="active-subitem if it is linking to the current controller and the action is not the default one. Hope that made sense... Anyone able to help me out here? Both in how to do this in Kohana 3 and also how it should be done in Kohana 3. I'm sure there are lots of ways, but yeah... any help is welcome :) Examples: domain.com -- Home should be active-item since it is the default controller domain.com/home -- Home should be active-item domain.com/home/index -- Home should be active-item since index is the default action domain.com/resources -- Resources should be active-item domain.com/resources/get/7 -- Resources should be active-subitem since get is not the default action

  • Symfony dynamic subdomains

    - by Jamie
    Hi all, I'm trying to match subdomains to a customer id in symfony. i.e. i have customer1.example.com and customer2.example.com Domains are stored in a table. When a user goes to customer1.example.com, I would like to get the subdomain, look up the domain name in the database, once matched, it will then deploy the app config for that customer and then store the customer_Id in a global attribute so i know exactly which customer I'm dealing with througout the whole application. The virtual host will have the relevant wildcard servername. Have you managed to achieve this, and if so, how? If not, any ideas would be a great help! I'm thinking about using a filter to do it. :-)

  • jquery set focus on dynamic content?

    - by Alan
    In jquery I've appended a <li> element to an unordered list. How do I focus on the newly created <li> ? If I do the following: $("ul").append('<li><input type="text">hi!</input></li>'); $("li:last").focus(); //doesn't work because new <li> isn't in dom yet the focus doesn't work, as noted above. I know jquery 1.4.2 has a live() event handler which allows you load event handlers to dynamically added elements, but I'm not sure what I'm doing wrong: $(document).ready(function () { $('li').live('load', function () { alert("hi!"); $("li:last").focus(); }); });

  • Sharepoint Web Part OnPreRender PostBack Dynamic TextBoxes Not Accessible In Button Handler

    - by Matt
    I have a custom webpart which extends System.Web.UI.WebControls.WebPart and implements an EditorPart. I have all the static controls being added in the overridden CreateChildControls method as I know this makes them persistent across PostBacks. However, I have some TextBoxes being added in the overridden OnPreRender method because the actual TextBoxes that I add depend upon the data returned from a Web Service which I am calling in OnPreRender. The Web Service has to be called in OnPreRender because I need some of the Property values that are set in the EditorPart. If I build this logic into the CreateChildControls method, obviously the data is not available on first PostBack after an edit is applied because the PostBack events are restored after CreateChildControls. This means the page has to be posted twice before the data is refreshed and that is just cludgy. How can make these TextBoxes along with their entered text values persistent across PostBacks so that I can access them in the button handler? Thanks for any help, Matt

  • Infragistics Webgrid (Datagrid) dynamic adjusting columns

    - by mattgcon
    I want to explain this as best as I can. I have a Webgrid with a certain amount of columns. What I want is for the columns to adjust to the size of the largest string within each column, where the total of all width of columns does not exceed the width of the webgrid. At the same time however if the width of all columns is less than the width of the webgrid I want each column to adjust proportionately so that the total of columns widths equal the width of the webgrid. Can anyone help me with this logic?

  • django - dynamic form fieldsets

    - by user110029
    A form will be spitting out an unknown number of questions to be answered. each question contains a prompt, a value field, and a unit field. The form is built at runtime in the formclass's init method. I'd like each question rendered on the form as an inline: prompt, value(input-text), units (select). this seems a case perfect for iterable form fieldsets, which could be easily styled. but since fieldsets - such as those in django-form-utils are defined as tuples, they are immutable... and I can't find a way to define them at runtime. is this possible, or perhaps another solution?

  • WPF - Dynamic tooltip

    - by Al Mackenzie
    I have a class ToolTipProvider which has a method string GetToolTip(UIElement element) which will return a specific tooltip for the UIElement specified, based on various factors including properties of the UIElement itself and also looking up into documentation which can be changed dynamically. It will also probably run in a thread so when the form first fires up the tooltips will be something like the visual studio 'Document cache is still being constructed', then populated in the background. I want to allow this to be used in any wpf form with the minimum effort for the developer. Essentially I want to insert an ObjectDataProvider resource into the Window.Resources to wrap my ToolTipProvider object, then I think I need to create a tooltip (called e.g. MyToolTipProvider) in the resources which references that ObjectDataProvider, then on any element which requires this tooltip functionality it would just be a case of ToolTip="{StaticResource MyToolTipProvider}" however I can't work out a) how to bind the actual elemnt itself to the MethodParameters of the objectdataprovider, or b) how to force it to call the method each time the tooltip is opened. Any ideas/pointers on the general pattern I need? Not looking for complete solution, just any ideas from those more experienced
