Out of Range exception editing datatable

[Josh]

I have a very simple RadGridView with its ItemsSource set to a datatable which I found here:
http://blogs.telerik.com/blogs/posts/10-01-22/how_to_serialize_your_datatable_to_silverlight_using_wcf_service.aspx

The grid loads fine but whenever I edit a cell and hit return, I receive an ArgumentOutOfRangeException.  Strangely, If I click on a column to sort it first and then edit a cell, everything works as expected.

Sample code below.  How can I prevent this error?

<Grid x:Name="LayoutRoot" Background="White">
    <telerik:RadGridView x:Name="gv1" ValidatesOnDataErrors="None"/>
</Grid>

Private Sub MainPage_Loaded(sender As Object, e As System.Windows.RoutedEventArgs) Handles Me.Loaded
    Dim Items As New List(Of Dictionary(Of String, Object))
    Dim Row1 As New Dictionary(Of String, Object)
    Row1.Add("Column1", "item1")
    Row1.Add("Column2", "item2")
    Row1.Add("Column3", "item3")
    Items.Add(Row1)

    Dim Row2 As New Dictionary(Of String, Object)
    Row2.Add("Column1", "item4")
    Row2.Add("Column2", "item5")
    Row2.Add("Column3", "item6")
    Items.Add(Row2)

    gv1.ItemsSource = New Telerik.Data.DataTable(Items)
End Sub

Thanks,

Hi Josh,

It took me some time to try reproduce the error here  but to no avail . I would offer an alternative way to assist you . Can you please attach your project. I will be glad to perform a small debugging session over it and see what goes wrong.

* In order to be able to attach a project you will need to open a support ticket.

Best wishes,
Pavel Pavlov
