• Adding interactions to admin pages generated by the admin generator

  - by Stick it to THE MAN

  I am using Symfony 1.2.9 (with Propel ORM) to create a website. I have started using the admin generator to implement the admin functionality. I have come accross a slight 'problem' however. My models are related (e.g. one table may have several 1:N relations and N:N relations). I have not found a way to address this satisfactorily yet. As a tactical solution (for list views), I have decided to simply show the parent object, and then add interactions to show the related objects. I'll use a Blog model to illustrate this. Here are the relationships for a blog model: N:M relationship with Blogroll (models a blog roll) 1:N relationship with Blogpost (models a post submitted to a blog) I had originally intended on displaying the (paged) blogpost list for a blog,, when it was selected, using AJAX, but I am struggling enough with the admin generator as it is, so I have shelved that idea - unless someone is kind enough to shed some light on how to do this. Instead, what I am now doing (as a tactical/interim soln), is I have added interactions to the list view which allow a user to: View a list of the blog roll for the blog on that row View a list of the posts for the blog on that row Add a post for the blog on tha row In all of the above, I have written actions that will basically forward the request to the approriate action (admin generated). However, I need to pass some parameters (like the blog id etc), so that the correct blog roll or blog post list etc is returned. I am sure there is a better way of doing what I want to do, but in case there isn't here are my questions: How may I obtain the object that relates to a specific row (of the clicked link) in the list view (e.g. the blog object in this example) Once I have the object, I may choose to extract various fields: id etc. How can I pass these arguments to the admin generated action ? Regarding the second question, my guess is that this may be the way to do it (I may be wrong) public function executeMyAddedBlogRollInteractionLink(sfWebRequest $request) { // get the object *somehow* (I'm guessing this may work) $object = $this->getRoute()->getObject(); // retrieve the required parameters from the object, and build a query string $query_str=$object->getId(); //forward the request to the generated code (action to display blogroll list in this case) $this->forward('backendmodulename',"getblogrolllistaction?params=$query_string"); } This feels like a bit of a hack, but I'm not sure how else to go about it. I'm also not to keen on sending params (which may include user_id etc via a GET, even a POST is not that much safer, since it is fairly sraightforward to see what requests a browser is making). if there is a better way than what I suggest above to implement this kind of administration that is required for objects with 1 or more M:N relationships, I will be very glad to hear the "recommended" way of going about it. I remember reading about marking certain actions as internal. i.e. callable from only within the app. I wonder if that would be useful in this instance?

• Creating a custom ribbon button in VS 2008 Standard

  - by Kevin L.

  I want to create a custom ribbon button within Outlook 2007 using Visual Studio 2008 Standard, but am unsure how to proceed. Most of the resources I've found mention VS 2008 Pro, and this SO answer mentions that VSTO is not even included in Standard. Is creating custom ribbon buttons possible using Visual Studio 2008 Standard? If so, where should I start?

• Flex custom item renderer for the displayed item in the combobox

  - by pbreault

  I am using a custom item renderer in a combobox to display a custom drawing instead of the default text label. This works fine for the dropdown list but the displayed item ( when the list is closed) is still the textual representation of my object. Is there a way to have the displayed item rendered the same way as the one in the dropdown?

• Small, Custom WYSIWYG editor

  - by Click Upvote

  I would make to make a small WYSIWYG editor similar to the one used by StackOverflow. Basically, it would have buttons like [quote], and when that button is clicked, [quote] [/quote] should be inserted in the textarea where the cursor is or at the end of all other text. If the [quote][/quote] could be highlighted in some way that would be even more excellent, but its not required. Is there any WYSIWYG editor already available where you can add custom buttons, with custom text being added to the textbox as a result?

• Removing the default pages when adding a domain via Plesk

  - by ChrisS

  Hi, whenever I add a new domain into my new Plesk control panel on my dedicated server it creates a whole bunch of test files in the cgi-bin, httpdocs and httpsdocs. There must be some setting somewhere where I can tell Plesk not to do this? I've done a good Google search but must now turn to the StackOverflow masses :) Yours, Chris

• Html.ActionLink in Partial View

  - by olst

  Hi. I am using the following code in my master page: <% Html.RenderAction("RecentArticles","Article"); %> where the RecentArticles Action (in ArticleController) is : [ChildActionOnly] public ActionResult RecentArticles() { var viewData = articleRepository.GetRecentArticles(3); return PartialView(viewData); } and the code in my RecentArticles.ascx partial view : <li class="title"><span><%= Html.ActionLink(article.Title, "ViewArticle", new { controller = "Article", id = article.ArticleID, path = article.Path })%></span></li> The problem is that all the links of the articles (which is built in the partial view) lead to the same url- "~/Article/ViewArticle" . I want each title link to lead to the specific article with the parameters like I'm setting in the partial view. Thanks.

• How to hide jQuery Sub-Menus(ddsmoothmenu)?

  - by Tim

  I'm new to jQuery and i must admit that i've understood nothing yet, the syntax appears to me as an unknown language although i thought that i had my experiences with javascript. Nevertheless i managed it to implement this menu in my asp.net masterpage's header. Even got it to work that the content-page is loaded with ajax with help from here. But finally i'm failing with the menu to disappear when the new page was loaded asynchronously. I dont know how to hide this accursed jQuery Menu. Following the part of the js-file where the events are registered for hiding/disappearing. I dont know how to get the part that is responsible for it and even i dont know how to implement that part in my Anchor-onclick function where i dont have a reference to the jQuery Object. buildmenu:function($, setting){ var smoothmenu=ddsmoothmenu var $mainmenu=$("#"+setting.mainmenuid+">ul") //reference main menu UL $mainmenu.parent().get(0).className=setting.classname || "ddsmoothmenu" var $headers=$mainmenu.find("ul").parent() $headers.hover( function(e){ $(this).children('a:eq(0)').addClass('selected') }, function(e){ $(this).children('a:eq(0)').removeClass('selected') } ) $headers.each(function(i){ //loop through each LI header var $curobj=$(this).css({zIndex: 100-i}) //reference current LI header var $subul=$(this).find('ul:eq(0)').css({display:'block'}) $subul.data('timers', {}) this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$subul.outerWidth(), subulh:$subul.outerHeight()} this.istopheader=$curobj.parents("ul").length==1? true : false //is top level header? $subul.css({top:this.istopheader && setting.orientation!='v'? this._dimensions.h+"px" : 0}) $curobj.children("a:eq(0)").css(this.istopheader? {paddingRight: smoothmenu.arrowimages.down[2]} : {}).append( //add arrow images '<img src="'+ (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[1] : smoothmenu.arrowimages.right[1]) +'" class="' + (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[0] : smoothmenu.arrowimages.right[0]) + '" style="border:0;" />' ) if (smoothmenu.shadow.enable){ this._shadowoffset={x:(this.istopheader?$subul.offset().left+smoothmenu.shadow.offsetx : this._dimensions.w), y:(this.istopheader? $subul.offset().top+smoothmenu.shadow.offsety : $curobj.position().top)} //store this shadow's offsets if (this.istopheader) $parentshadow=$(document.body) else{ var $parentLi=$curobj.parents("li:eq(0)") $parentshadow=$parentLi.get(0).$shadow } this.$shadow=$('<div class="ddshadow'+(this.istopheader? ' toplevelshadow' : '')+'"></div>').prependTo($parentshadow).css({left:this._shadowoffset.x+'px', top:this._shadowoffset.y+'px'}) //insert shadow DIV and set it to parent node for the next shadow div } $curobj.hover( function(e){ var $targetul=$subul //reference UL to reveal var header=$curobj.get(0) //reference header LI as DOM object clearTimeout($targetul.data('timers').hidetimer) $targetul.data('timers').showtimer=setTimeout(function(){ header._offsets={left:$curobj.offset().left, top:$curobj.offset().top} var menuleft=header.istopheader && setting.orientation!='v'? 0 : header._dimensions.w menuleft=(header._offsets.left+menuleft+header._dimensions.subulw>$(window).width())? (header.istopheader && setting.orientation!='v'? -header._dimensions.subulw+header._dimensions.w : -header._dimensions.w) : menuleft //calculate this sub menu's offsets from its parent if ($targetul.queue().length<=1){ //if 1 or less queued animations $targetul.css({left:menuleft+"px", width:header._dimensions.subulw+'px'}).animate({height:'show',opacity:'show'}, ddsmoothmenu.transition.overtime) if (smoothmenu.shadow.enable){ var shadowleft=header.istopheader? $targetul.offset().left+ddsmoothmenu.shadow.offsetx : menuleft var shadowtop=header.istopheader?$targetul.offset().top+smoothmenu.shadow.offsety : header._shadowoffset.y if (!header.istopheader && ddsmoothmenu.detectwebkit){ //in WebKit browsers, restore shadow's opacity to full header.$shadow.css({opacity:1}) } header.$shadow.css({overflow:'', width:header._dimensions.subulw+'px', left:shadowleft+'px', top:shadowtop+'px'}).animate({height:header._dimensions.subulh+'px'}, ddsmoothmenu.transition.overtime) } } }, ddsmoothmenu.showhidedelay.showdelay) }, function(e){ var $targetul=$subul var header=$curobj.get(0) clearTimeout($targetul.data('timers').showtimer) $targetul.data('timers').hidetimer=setTimeout(function(){ $targetul.animate({height:'hide', opacity:'hide'}, ddsmoothmenu.transition.outtime) if (smoothmenu.shadow.enable){ if (ddsmoothmenu.detectwebkit){ //in WebKit browsers, set first child shadow's opacity to 0, as "overflow:hidden" doesn't work in them header.$shadow.children('div:eq(0)').css({opacity:0}) } header.$shadow.css({overflow:'hidden'}).animate({height:0}, ddsmoothmenu.transition.outtime) } }, ddsmoothmenu.showhidedelay.hidedelay) } ) //end hover }) //end $headers.each() $mainmenu.find("ul").css({display:'none', visibility:'visible'}) } one link of my menu what i want to hide when the content is redirected to another page(i need "closeMenu-function"): <li><a href="DeliveryControl.aspx" onclick="AjaxContent.getContent(this.href);closeMenu();return false;">Delivery Control</a></li> In short: I want to fade out the submenus the same way they do automatically onblur, so that only the headermenu stays visible but i dont know how. Thanks, Tim EDIT: thanks to Starx' private-lesson in jQuery for beginners i solved it: I forgot the # in $("#smoothmenu1"). After that it was not difficult to find and call the hover-function from the menu's headers to let them fade out smoothly: $("#smoothmenu1").find("ul").hover(); Regards, Tim

• How to create a static header that remains even when navigating to other pages (lala.com)

  - by user169867

  I'm interested in the way lala.com works. They have a header that remains fixed at the top of the browser and they have a flash music player in it. You can click on other links in the site and they are displayed below the header but the header is not disrupted and can continue playing music. If the target is a modern browser say IE8 & FF 3.6, what's the best way to achieve this? Thanks for any help.

• Can I make controls defined in my markup public instead of protected

  - by RoboShop

  Say I have a web site with a master page and an aspx page. In my ASPX page, I am pointing to my masterpage with the MasterType tag. <%@ MasterType VirtualPath="~/mymasterpage.master" % Say, I've defined a label in the markup of my master page. If you look at the designer code, this label should be something like this. protected global::System.Web.UI.WebControls.Label label1; Now in my content page, I would like to reference this label. If I type in this "Master.label1", the complier will complain that the control is inaccessible due to the protection level" and rightly so, as label1 is automatically defined as "protected". My question is, if I define controls in my markup page, is it possible to set these controls as public instead of protected? I do not see an attribute for it. thanks in advance.

But if I press the login button the page just reloads itself, nothing happens. The codebehind on this page is empty. Both LoginContent.aspx and Welcome.aspx are child forms of the same master page. <form method="post" action="~/Welcome.aspx"> Username: <input type="text" name="username" size="15" /><br /> Password: <input type="password" name="passwort" size="15" /><br /> <input type="submit" value="Login"/></p> </form> I know I could use the asp.net login control but I want more control over things.

  How can I hide the root node in a SiteMapPath control when the user is on the root node page? For example, my breadcrumb trail on a child page is: Home Products Hammers Ball Peen which is fine. But when the user is on the Home page, the SiteMapPath control displays Home which is useless clutter. I want to suppress displaying Home (the root node) when the user is on the home page. I have the SiteMapPath control in a master page. Also, I'm handling SiteMapResolve to set the querystrings in the nodes.
