Upgraded to WPF Q3 2009 and Hierarchy doesn't work anymore

[Brian Thomas]

Due to some errors I was having in Q2, I thought I would upgrade to Q3. Now my Grid's hierarchy doesn't work anymore. I installed the update, removed my references from my project, then added the new ones. The plus signs load but they don't actually expand when clicked.

I looked at the examples and made one change to reflect the example but still no luck.

Hi Brian,

Here is an example how to fix this:

...
<telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <telerik:RadGridView x:Name="ProdData" ItemsSource="{Binding ProddataRecs}" AutoGenerateColumns="False">
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn Header="PCWNO" UniqueName="PCWNO" />
                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>
                </DataTemplate>
            </telerik:RadGridView.HierarchyChildTemplate>
...

Best wishes,
