Hello,

 Can you clarify if this stack trace is from some of our assemblies?

Hi,

 Can you bind the same to regular ListBox?

[Afsal]

Using listbox it is working fine.
this is the code i used:
MainWindow.xaml:
<ListBox x:Name="lstTest">
</ListBox>
MainWindow.xaml.vb:
lstTest.ItemsSource = GetXmlData()

Hello,

Please let me know if there any fix for this issue as soon as possible.

Hello Afsal,

We were able to reproduce your issue when we have retargeted the example to use .NET 3.5 . We will implement a fix for this in one of our next latest internal builds.

Thanks for pointing out this issue. I have updated your Telerik points respectively. I have also created a PITS item (#4815) for you in order to track the status of this bug.
