Weird GridView exception

[Slavisa Radicevic]

Hello, since we put Q1 2010 build in our application, we are getting weird exception, currently noticed only on one screen. In other screens GridView works almost as before. This is the exception:

Error: Unhandled Error in Silverlight Application
Code: 4004    
Category: ManagedRuntimeError       
Message: System.InvalidOperationException: MeasureOverride of element 'Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel' should not return PositiveInfinity or NaN as its DesiredSize.
   at System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)

This exception happens when there are rows in the grid, when we remove ItemSource it works ok. Any help would be very appreciated, at least some suggestion where to look.

Thanks.

Hello,

Can you send us an example where we ca reproduce and debug this? Can you try our latest internal build to see what will be the result?

Hello,

I've checked your site and indeed there is an error in this case - can you try the latest build instead (or wait for our upcoming official service pack later today)? Since I don't know how the grid is declared and/or bound in your case I'm not sure if I will able to give any more information about reason unless you send us small example project where we can reproduce the exception.

Best wishes,

Hello,
Thanks for looking at the application. I will wait for the service pack then, and see if application, maybe, starts to work. If it doesn't, I will try to make small app and send it to you.

Hello,
I found what caused the error, but I haven't found out why. The problem was in the style for RadGridView, that looked like this:

<Style x:Key="ListScreenGridViewData" TargetType="grid:RadGridView">
        <Setter Property="DataLoadMode" Value="Asynchronous" />
        <Setter Property="ScrollMode" Value="Deferred" />
        <Setter Property="Height" Value="460" />
        <Setter Property="Background" Value="#FFDDE7F4" />
 </Style>

When I removed DataLoadMode property, RadGridView started to work. I don't know why did this affect grid view, but important thing is that it works now.

Place a radgridview in a stackpanel,then click column header to sort,the exception will occur. 

I think it is busy indicator cause this.

I forget to say,tht radgridview should not set height and width to reproduce the exception.

Hello,

Unfortunately, we were unable to reproduce the exception. Could you give us more details about the data or send a sample application? Also, could you try to get the exception with our latest internal build (version 0521)?

Kind regards,

To reproduce the exception, just change the LayoutRoot grid to stackpanel in

http://www.telerik.com/community/forums/silverlight/gridview/server-side-paging-sorting-example.aspx

which attached project by Vlad.

Hi yjh,

We managed to get the exception and it was fixed immediately. The fix will be included in our incoming SP2 this week. Thank you for the feedback.

Hi,

Is this fixed in version 2010.2.609.1040?
I get the same error with this version.

Is there a workaround?

Regards,
Fabrice

Hello Fabrice Marguerie,

The problem was resolved in our Q1 2010 SP2 (version .603) and respectively our Q2 2010 Beta (version .609) contains the fix. We just try it and everything works fine - no such exception occurs.
Please, give us more details about your case or send a sample application where the problem can be seen.

I think that my case is different. I'll submit a support request with a code sample.

Thanks.
