Ajax Control Toolkit problem

Posted by on March 26, 2008 Leave a comment (16) Go to comments

I need to research this a bit more, but I will give a quick fix that I did.

So, I started an AJAX Web Application in Visual Studio 2008 and then added the latest Ajax Control Toolkit for 3.5.  I made a simple page and wanted to use the Auto Complete Control.  So, I added a simple text box and then added the Auto Complete Extender.  There was then a item to add the event of this control to your code behind.

I got this error:

Cannot create page method “GetCompletionList” because no CodeBehind or CodeFile was found.

I spent quite a few hours looking throuh solutions and couldn’t find anything that was of much help.

I decided to start over.  I created the application a little differently this time.  Instead of a new project, I started a New Web Site.  Repeated the same steps and it works fine.

UPDATE:
The problem has to do with VSWebProjectItem.  The standard AJAX Web Application with project file does not consider itself a “Web Project” and causes the AJAX toolkit to error.

    @Grahame

    Instead of creating a “Web Site” create a standard project.

    File..New..Project and not File..New..Web Site

    I am trying to use the AjaxControlToolkit in a ASP.NET Web Application and it won’t recognize me the ajaxtoolkit tags. I added the dll as a referece, but still no luck.

    You may need to add the reference to the ajax controls in your aspx page.

    <%@ Register assembly=”AjaxControlToolkit”
    namespace=”AjaxControlToolkit” tagprefix=”ajax” %>

    I’ve got the same issue. I created a new project (not website) and the reference is there however it was called “cc1″ instead of ajax :S I renamed it but it didn’t help.

    first add that dll file into c:/windows/microsoft.net folder.Then open VS2010,
    right click "General" tab in toolbox -> add tab. give an appropriate name, then right click on it and click "choose items", then browse to the path where the dll file resides. and click ok.

    I tried creating a project and also a web site. I also tried reinstalling the AjaxControlKit DLL. Unfortunately I’m still getting the same error. Has anyone had any luck solving this?

    I have downloaded in ajax control tool kit3.5 and uploaded in .net 2008 env successfully. Afterward, i have used simple calender control in sampleWebsite/sampleProject. I able view the textbox in IE/Firebox browser env but calender extender control is not working. Similarly, any ajax controls are not supported in IE/Firebox browser.

    <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

    —
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
    —
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

    <cc1:CalendarExtender ID="CalendarExtender1" runat="server" Enabled="True"
    TargetControlID="TextBox1">
    </cc1:CalendarExtender>

    and i have added the below comments in web.config file
    <pages>
    <controls>
    <add namespace="AjaxControlToolkit" assembly="AjaxControlToolkit" tagPrefix="cc1"/>
