    I'm getting the following Warning, preceded by a Stack Overflow Exception whenever I click on any of the items in my TreeView, which is inside a DropDownButton.

    System.Windows.Media.Animation Warning: 6 : Unable to perform action because the specified Storyboard was never applied to this object for interactive control.; Action='Stop'; Storyboard='System.Windows.Media.Animation.Storyboard'; Storyboard.HashCode='55034768'; Storyboard.Type='System.Windows.Media.Animation.Storyboard'; TargetElement='System.Windows.Media.Animation.Storyboard'; TargetElement.HashCode='55034768'; TargetElement.Type='System.Windows.Media.Animation.Storyboard'

     

    And my XAML:

    <telerik:RadDropDownButton.DropDownContent>
                        <telerik:RadTreeView ItemsSource="{Binding ProjAreaPaths}"
                                             SelectedItem="{Binding Path=AreaPath, Mode=TwoWay}"
                                             ItemContainerStyle="{StaticResource RedStyle}">
                            <telerik:RadTreeView.ItemTemplate>
                                <HierarchicalDataTemplate ItemsSource="{Binding ChildNodes}"
                                                          ItemContainerStyle="{StaticResource GreenStyle}">
                                    <TextBlock Text="{Binding Name}"/>
                                </HierarchicalDataTemplate>
                            </telerik:RadTreeView.ItemTemplate>
                        </telerik:RadTreeView>
                    </telerik:RadDropDownButton.DropDownContent>
                </telerik:RadDropDownButton>

    Hello George,

    I tested your code, but I wasn't able to reproduce the reported error. Can you share some runnable code demonstrating the issue?

    As a side note, I don't think the storyboard error shown in the Output is related to the StackOverflow exception. This warning appears in some cases, but it doesn't affect the treeview proper running.

    Hi Martin,

     

    I am at a complete loss as for what to say. I never managed to diagnose the cause but the exception no longer occurs, I simply cannot replicate my previous error.

     

    Thank you I did eventually realise that the warning was unrelated.

     

    Thank you for your reply, and apologies for wasting your time it would seem!

     

    Regards,

    George
