Hello, after upgrading to Q3 2011 for silverlight I am seeing this unhandled exception:

Unhandled Exception 4004
ManagedRuntimeError
System.ArgumentOutOfRangeException: Index was out of range
Must be non-negative and less than the size of the collection

It appears to happen when opening a ChildWindow
Also happens when clicking on a tab folder.
We are using VS 2010 Silverlight etc.

Can someone help me diagnose and correct?
Nothing I do seems to help.

I was able to resolve the issue by removing all DisplayIndex="xx" attributes from the XAML.
The first Display Index was always set to zero and then incremented up from there.

Did this break in Q3 2011?

Hello,

 We are not aware of any breaks related to DisplayIndex.

If any grid has the display index values set like below the error occurs even if there is no data.

<telerik:RadGridView.Columns>
    <telerik:GridViewImageColumn Header="Priority" DisplayIndex="0" IsFilterable="False" IsGroupable="False" IsReadOnly="True" IsSortable="False" ShowDistinctFilters="False" UniqueName="PriorityImageName" DataMemberBinding="{Binding PriorityImageName}" />
