Exception : {"'System.Windows.Documents.Hyperlink' is not a Visual or Visual3D."}

My XAML:

<telerik:RadTreeView  ItemsSource="{Binding Doklad.polozky}">


                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                                <TextBlock Grid.Column="2">
                                    <Hyperlink TextDecorations="None"
                                               Command="{Binding EditPolozkaCommand, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type UserControl}}}"
                                               CommandParameter="{Binding}">
                                    <Image  Grid.Column="2"  Width="16" Source="/Assets/Icons/Edit.png" Cursor="Hand"/>
                                    </Hyperlink>
                                </TextBlock>

                            </Grid>
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>

Hi Jaroslav Půbal,

 According to the code you are using RadTreeView not RadTreeListView and indeed you cannot use System.Windows.Documents.Hyperlink in this case. I strongly suggest you to visit this MSDN article for more info:
http://msdn.microsoft.com/en-us/library/system.windows.documents.hyperlink.aspx

All the best,
Vlad

I read http://msdn.microsoft.com/en-us/library/system.windows.documents.hyperlink.aspx
and nothing about use Hyperlink in DataTemplate or use Hyperlink with Command.

I think it is problem in RadTreeView since in other components this datatemplate is working.

Hello Jaroslav Půbal,

Can you please test your solution with the latest internal build and let us know if you still experience this issue?

Thank you in advance.

Kind regards,

I'm running into the same issue. It seems to occur when a RadTreeView loses focus to a Hyperlink (System.Windows.Documents.Hyperlink)

[Petar Mladenov]

Hello Cody,

 We had such exception (which is really rare) in old versions of our RadTabControl andRadOutlooBar ( the RadOutlookBar inherits from RadTabControl).  Do you use these controls in your sample and what is your dlls version ? If this has nothing do with your scenario, could you please try to set Focusable = false in all System.Windows.Controls.Hyperlinks in your project ? 

Best wishes,
Petar Mladenov

Hi, Petar,
The Hyperlink object is within a RadTabControl. I'm using version 2011.2.0920.35.

Hi Cody,

The first official build to provide a fix for this issue is the Q3 2011. You can also try the latest internal build 1107 from your account page at www.telerik.com. Please let us know if this solves your issues.

Best wishes,
