I have a problem in using RadChart of asp.net ajax 2009.1.402.35 inside asp.net MVC2 projects. The chart works fine if I put the ChartTest1.aspx page directly under the project folder. However, if I put a page "ChartTest2.aspx" in a folder (projectroot/ChartPages/ChartTest2.aspx), error happens (the resouce cannot be found...., and Requested URL:/ChartPages/ChartImage.axd).

I think this is due to page routing issue. To be more specific, the application is a hybric platform of Webfrom and Webview. However, I know it is compatible. The issue is how to set the corretc rounting. I have tried a trick in another post by putting code "

RadChart1.HttpHandlerUrl = ResolveUrl(

"ChartImage.axd") behind. can someone help me resolve the problem?

I have a RadTabStrip that just refuses to show up when page loads or reposts. Not certain what I would need to do to get this working at this point. No where in my code do I disable the control for it not to show up when loaded.

<telerik:RadTabStrip ID="RadTabStrip1" AutoPostBack="true" runat="server" OnClientTabSelecting="TabSelecting"/> 

The Tabcollection is filled on postback, so I am not certain why this is happening. Even explicitly setting the enable property to true both on the client and the server side does not seem to work. Any idea what the problem might be?

Thanks in advance!

HI,

I get an error when I try to apply a filter on the value of a combobox. I have placed the combobox in a telerik:GridTemplateColumn.
When I filter on any other column it works as expected.

Here is the code

And the Error message:

Server Error in '/' Application.
