A compilation error has occurred.

[Fred Koehlmann]

I have an existing ASP.NET web application built in VS 2005 (.NET2.0) that contains existing Telerik ASP.NET Q1 2009 controls on the content page (RadAjaxManager, RadGrid plus a number of asp:dropdown, asp:ListBox and asp:Panel controls). The master page contains a RadMenu control, but I don't believe this is causing my issue.

My issue is that I am now planning on replacing some of the dropdown and ListBox controls with one telerik:TreeView control (ASP.NET AJAX Q2 2009 NET20). My understanding is that I need the telerik:RadScriptManager as well to get this the tree view to work. Unfortunately the page loads with an error "A compilation error has occurred.". In a test page without the classic controls the page loads OK, and the exisitng works fine without the new controls. In attempting to debug the code, I never find where the issue is. Just trying to load the page just kick me right out. The event viewer logs the below warning:

I have reviewed some of the forums messages and it seems that some people have had difficulty when combining the older classic controls with the newer ajax ones, but I didn't see anything like this. Do I need to update my old controls? If so what issue will I encounter when upgrading the RadGrid?

Thanks, Fred.

Hi Fred Koehlmann,

The error:

   Exception message: D:\TFS\PIMS\PIMS - Current\solutions\wwwroot\PIMS_2008\UserProfileTreeViewTest.aspx(203): error BC30456: 'cbViewLocation_CheckedChanged' is not a member of 'ASP.userprofiletreeviewtest_aspx'.

seems like the code behind page does not have the definition of the CheckedChanged event handler. Can you check that please.

All the best,

Thanks for the response Veselin,

The code behind pages do have the accompanying event methods, since they were there from the existing rad:GridView control. The checkboxes in question are contained with its template columns.

I've done additional playing around and  it seems that after I removed the telerik:RadScriptManager and replaced it with the asp:ScriptManager and registered it in the web.config file (as mentioned elsewhere in one of these forums), the error went away. So at this point I have it working, but I guess I don't really understand the difference between the Microsoft asp:ScriptManger and the Telerik telerik:AjaxScriptManger and why the difference.

I suppose this post could be relocated to the ScriptManger forum.

Cheers, Fred.

Hello Fred Koehlmann,

RadScriptManager inherits ScriptManager class and adds the functionality of combining the embedded javascript files into one file. In addition it compresses that file so it gets to the client faster.
Which browser do you test with? I know that the older versions of IE6 cannot decompress streams and this could cause javascript errors. But the error you pasted is a compilation error so I am a bit confused.

If you could open a support ticket and attach a sample project there would be ideal.

Kind regards,
