RadGridView Grouping issues #2

[tjuncewicz]

On a RadGridView with grouping, if you select the last row and hit the keydown a few times, the application appears to "freeze" up for 1-2 minutes.  It eventually comes back to life, but appears to be frozen.  Only seems to happen if you try to keydown past the last row in the grid.  Any help would be appreciated.  I should add that this behavior appears on a 64-bit Windows 7 OS. Another developer with 32-bit WIndows 7 does NOT have this issue.  Thanks!

XAML:

<tel:RadGridView x:Name="ListsGV" Grid.Row="2" ItemsSource="{Binding EditFormViewModelCollection}"
        IsReadOnly="True" SelectedItem="{Binding CurrentEditFormViewModel}"
        PreviewMouseDoubleClick="gridView_PreviewMouseDoubleClick"
        HeaderRowStyle="{StaticResource HeaderStyle}"
        CanUserSortColumns="False">

  <prism:CommandBehaviorCollection.Behaviors>
    <prism:BehaviorBinding Event="MouseDoubleClick" Command="{Binding TableSelectedDoubleClickCommand}" CommandParameter="{Binding ElementName=ListsGV, Path=CurrentItem}" />
  </prism:CommandBehaviorCollection.Behaviors>

  <tel:RadGridView.GroupDescriptors>
    <tel:GroupDescriptor Member="CurrentList.SystemModule" />
  </tel:RadGridView.GroupDescriptors>
  <tel:RadGridView.GroupHeaderTemplate>
    <DataTemplate>
      <TextBlock Text="{Binding Header.Description}" Margin="1,0,0,0" />
    </DataTemplate>
  </tel:RadGridView.GroupHeaderTemplate>

  <tel:RadGridView.Columns>
    <tel:GridViewDataColumn Header="Description" DataMemberBinding="{Binding CurrentList.Description}"
        HeaderCellStyle="{StaticResource HeaderCell}" MinWidth="300" />
    <tel:GridViewDataColumn Header="Shared Operations" DataMemberBinding="{Binding CurrentList.SharedOperation}"
        HeaderCellStyle="{StaticResource HeaderCell}" Width="*"/>
  </tel:RadGridView.Columns>
</tel:RadGridView>

Hello Tjuncewicz,

I tried to reproduce the described problem but without any success. Could you try to update your project with our latest official version Q2 2011?
