Hi

I have a tabControl with 2 tabItems. Each of which contains a GridView that is bound to a RIA datasource.

<telerik:RadTabControl>

<telerik:RadTabItem Header="Tab 1">

<telerik:RadGridView .... />

</telerik:RadTabItem>

<telerik:RadTabItem Header="Tab 2">

<telerik:RadGridView .... />

</telerik:RadTabItem>

</telerik:RadTabControl>

When I switch tabItem for the first time I will get the following error:

Microsoft JScript runtime error: Unhandled Error in Silverlight Application Object does not match target type.   at System.Reflection.RuntimeMethodInfo.CheckConsistency(Object target)

at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)

at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

at System.Reflection.EventInfo.RemoveEventHandler(Object target, Delegate handler)

at Telerik.Windows.Data.WeakEvent.WeakListener`1.Unsubscribe()

at Telerik.Windows.Controls.GridView.GridViewScrollViewer.OnUnloaded(Object sender, RoutedEventArgs e)

at MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)

at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

If I ignore the error the tabItem is changed and the corrosponding GridView is loaded and everything is fine. I can then swich between TabItems without any further errors occuring.

This is mighty strange, is there anyway I can prevent the error from occuring?

Thank you for any help.
