MVC :: Script Not Loaded By Ajax If It Is The First Element Under The Ascx Header
Jul 14, 2010
I have 2 similar partial views.
View #1:
[Code]....
View #2:
[Code]....
In my Index.aspx view I have 2 Ajax.ActionLinks that load these partial views into a div. The problem is, in the 2nd case the script is not loaded. Here are screenshots from IE8 developer tools (F12):
Screen #1:
Screen #2:
The sample MVC application is here: [URL]. The actual application I'm having this problem with uses jQuery.globalEval() to execute these scripts. Currently I have to insert <div style="display:none"> </div> before the script tag if it happens to be the first one in order to make it work.
I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.
This doesn't happen when I create the site in my local drive. Is there a workaround to this. Even if I add the missing parts, I keep getting the same error.
I upgraded from VS 2008 to VS 2010 and now the AJAX elements are not recognised by the source code editor, e.g. UpdatePanel, ScriptManager, etc. I get warnings in VS and no intellisense for those elements. When I run the site, all the AJAX controls work OK though.
Element 'AsyncPostBackTrigger' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.
My app is working properly but visual studio showing warning like that.
I am having a asp.net page where I am using Ajax Tab control. When i am running the page, the text of all tab is not able to view. I want to change the height of Header text.
I have to build a few ascx partial views in my MVC applications to encapsulate re-usable functionalities as well as archive SOR and SOC. However, I encountered challenge how to encapsulate the business logic that drives MVC ascx views.In webforms, the code behind of an ASCX control can handle a button click event and browser still shows the same page with only one postback. How can I archive the same thing in MVC? When ~/Address/Edit/2 includes an ascx partial view with a button on it that calls another MVC action - let's say ~/ShareController/CommonAction - what is the best way for the CmmonAction to return to the very same view that includes the ascx file?Perhaps I am missing a common pattern in MVC web development?
I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null.
ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked.
rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here [URL]
I have an ascx with Update panel and an ADD button in it. I have included the ascx in a apsx with an update panel in it.Now when I clicking on the ADD, first time the postback is firing fine but the second time the add button event is not firing but again in third time it's firing and forth time it's again not firing and so on.....I have a delegate to handle the postback in the ascx...
would love to popup a created ascx control.in my aspx page i have a button like button1modalpopupextender targetcontrolid is button1 and popupcontrolid is the one of the ascx control.everything works. have MANY buttons (more than 2) inside the ascx control.depending on WHICH button i push INSIDE the ascx control, the controls returns me back a valuebut the server side event for button1 is no more fired after extending with modalpopupextenderso what i need is to specify the modalpopupextender a method to call after ANY button inside the ascx control has been pressed.i did not find a solution until know.it WOULD HELP ME if, i click my button1, the modal popup displays, i can click inside there, and after i click inside the modal popup, the event for button1 server side would be raised, but this does not.i tried event for modalpopup unload but it crashes my webserver.so why this all? i created a ascx which will be dynamically filled with buttons and text depending on what i need.
I'm developing second language support for the site. So I made duplicate .ascx and .aspx files for existing ascx.cs and aspx.cs
Most of the time everything works fine.. but suddenly I'm getting:
Type 'ctrl_car' exists both in 'c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files zhdengined072cc729d5698bApp_Web_xdmblegv.dll', and in 'c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files zhdengined072cc729d5698bApp_Web_gkptrzo2.dll' (translated from russian) ctrl_car ctrl = (ctrl_car) LoadControl("car.ascx");
I have few such strings of code... and same error occurs with one of them. But WITHOUT any changes from me with those files. To fix thaat bug for some time I need to delete solution and website folder and reget them from SS. Solution was converted from vs2005.
I'm looking at an asp.net application, i notice that there are assemblies defined into two places. In web.config there is configuration/system.web/compilation/assemblies/add elements. In the project file there are references setup under the Project/ItemGroup/Reference elements.
I was wondering, what is the difference between assemblies/references added in either location?
AutoCompleteExtender (4.1.4.0) in update panel in user control (ascx) and webservice under his ascx.vb and doesn't works.
So I've tested the same markup and webservice method in a simple aspx page and works, so I've some doubt:
- AutoCompleteExtender works in ascx file with webservice function under his code?
- AutoCompleteExtender works in an update panel?
I've always problem to create webservice method using wizard on the control, it return always: Cannot create page method GetCompletionList because no CodeBehind or CodeFile was found! - but I've CodeBehind file..sure!
I'm developing an ASP.NET application and I'm trying to do the following:
I'm going to have only one ASPX page splitted into two columns. On the left column is going to be a TreeView, and on the right column is going to be something to edit treeview's nodes.
When the user can select a treeview's node to edit on the right column. Depending on the node's depth fields on right column will vary.
I wondering to use ASCX controls and load on right column dinamically using AJAX, for example. Is there a better choice? Can I do that?
I don't want to reload the entire page when the user wants to edit a treeview's node. Maybe I'm going to need an UpdatePanel on the right column to load dinamically ASCX controls, isn't it?
display the first tier of data so the user can select and tweak desired rows. On occasion, they will want to drill into a row to see the children and select/tweak them. After a tweaking session, I wanted to be able to commit.
If I build an aggregate ViewData and prepopulate it, I can display it just fine in the View, and I get the collection back in the postback just fine.
Starting with empty child data, I experimented with jscript to fetch that data and displayed it by adding elements with jquery.
What I can't figure out how to do is to return that data to the controller. The newly added elements aren't in "Show Source" ... I heard elements added via jscript are not posted back. I even tried adding items to a prepopulated list ... only those items originally passed in are returned.
is anybody interesting in share and join to develop callback web controls. My purposes is lower unsynchronized page development cost. I have developed a base class and a set of common controls. Currently, they allowed to be loaded dynamically in a control or ASCX via callback event using sample server side code. Control library code will automatically register javascript and render it on client browser. These controls worked fine in both callback and postback. To load dynamically from an ASCX file.
'ascx1.ascx contain some callback-able controls Private Function LoadAscx_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String Dim rt As String = "" div1.Controls.Clear() Dim c As Control = LoadControl("~/Test2/ASCX/ascx1.ascx") c.ID = "ascx1" div1.Controls.Add(c) If RenderMe Then rt = CallbackManager1.RenderControlHelper(c) Return rt End Function Or to load dynamically as a control 'c is a callback-able TextBox Private Function LoadControl_DuringCallback(Optional ByVal RenderMe As Boolean = False) As String Dim rt As String = "" div1.Controls.Clear() Dim c As New ACT360_CallbackControls.ZYH.TextBox AddHandler c.KeyUp, AddressOf TextBox_KeyUp AddHandler c.GetFocus, AddressOf TextBox_GetGocus div1.Controls.Add(c) If RenderMe Then rt = CallbackManager1.RenderControlHelper(c) Return rt End Function
I have three UpdatePanels on my ascx page. In first I have gridview, in second I have DetailView. DetailsView is in a Panel, after click on buttom -Panel show or hide. All works fine. I added third Panel, new Buttom , inside Panel I put UpdatePanel and I would like the some function as in DetailView - show or hide Panel.After click on buttom I can see this error-Sys.InvalidOperationException: Could not find UpdatePanel with ID 'xxxxxxxxxxx. If it is being updated dynamically then it must be inside another UpdatePanel.
I tried many examples, whitch I found on the internet (move Buttom on page - change its position, add UpdateMode="Conditional" to the UpdatePanel), but without any resolution.
I have found a couple of good topics here in the forum and wanted to see any other extra ideas for this control that I am making and trying to implement. So here is the basic information:
The control is going to display a SQL output in a bunch of label controls. The information is going to be coming from a gridview control where the field is going to be hyperlinked.
So I am wanting to set the "TargetControlID" property to the .ascx page load event.
now what I have found is that I can simply run the Popup.show(); function in the .cs file at the end of the page load, but I still have to place a valid control within the TargetControlID property. As you know, the property cannot be "null" and if I put in the control ID for something that is not valid, then it won't work either. So the only thing I can think of is tying it back to the overall control itself. Then I can always change it on the fly if needed, but I think I would not have to since it would fire on the page_load event...
Not sure if this is making any sense... Just understand that have to make this control go across several web pages that are already fully developed. I am just adding this in as new functionality...
I would like to select an element that is in the same TR as another element I found with a selector. The selector itself: $("input[name='sMessageValue']","#messageTable") Now I have this element and got its value I would like to find a checkbox located in the same TR, i tried this as starting point : $(this).(':parent').val(). But seems not the right thing to do.
You're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap
Is it possible to validate a form that has been loaded dynamically by Ajax? I have two forms that I load on a page with another form and niether of the Ajax forms can be validated.
Have a GridView in an UpdatePanel, all works fine. Click the Submit() button which updates the database on postback, then the GridView is bound in code and I register an alert:
Calling UpdatePanel1.Update() causes the popup to appear. All fine but what I am noticing is that the alert occurs just before the page has fully updated and is causing a few minor layout issues that are resolved when the alert button is closed (by clicking OK). Is there a way to generate an alert after a full UpdatePanel refresh, so something like:
I just create a js file and write all my codes into it after i added this file to UserControl and after i get this UserControl's html i use $("#DivID").html(UserControlHTML);
Its working now.
Hi everyone;
Im using Ajax and Webservice to load UserControls. Its ok i can easily get the html code of UserControl but there is a problem.
For example UserControl's html code is something like that.
<h3>Header</h3> <div id="content"> <p>lorem ipsum dolor sit amet...</p>[code]....
When i get this html code and insert it to an div's innerHTML.html looking as it should. But javascript codes which written on usercontrol not working.It should give me alert but its not.
