Hello, I am using the RadDocking to manage a collection of panes.  I have a DataTemple with a EditableContentControl to allow modification of header text.  This works quite well with the exception of when a pane is moved to a new group.  When a RadPane is removed from the initial RadPaneGroup and placed in a new location, and I add a new pane, all RadPanes in the new RadPaneGroup do not utilize the DataTemplate defined in the initial.  Is there some resolution to this?
You can see from the XAML below that I am binding the ItemSource for the RadPaneGroup to a collection using an extension.  The newly greated RadPaneGroup does correctly bind to the collection of panes so I had assumed that the DataTemplate too would be applied.

Thanks

Paul

<Grid>
   <TelerikDocking:RadDocking>
     <TelerikDocking:RadDocking.DocumentHost>
       <TelerikDocking:RadSplitContainer>
         <TelerikDocking:RadPaneGroup Extension:PaneGroupExtensions.ItemsSource="{Binding Panes, Source={StaticResource QueueWindowViewModel}}">
           <Extension:PaneGroupExtensions.ItemHeaderTemplate>
             <DataTemplate>
               <Grid>
                 <Root:EditableContentControl Content="{Binding HeaderText, Mode=TwoWay}"/>
               </Grid>
             </DataTemplate>
           </Extension:PaneGroupExtensions.ItemHeaderTemplate>
         </TelerikDocking:RadPaneGroup> 
       </TelerikDocking:RadSplitContainer>
     </TelerikDocking:RadDocking.DocumentHost>
   </TelerikDocking:RadDocking>
</Grid>

Hello Paul,

Could you please review the attached project - it illustrates how to use the extension and set a DataTemplate to the Item and the Header. If you could modify it, so the issue is reproduced it will be very helpful for tracking down the source of the issue.
Please keep in mind, that this is not a supported feature out-of-the-box, just a work-around we have suggested, so some limitations might be present.

Kind regards,

The following is the response from Telerik:
All that is needed to be done is to add the ItemHeaderTemplate as an implicit style, so that it can apply to the newly generated PaneGroups.

In my XAML I had incorrectly attempted this.  The correct syntax is:

<Style TargetType="Telerik:RadPaneGroup">

  <Setter Property="Extension:PaneGroupExtensions.ItemHeaderTemplate">

    <Setter.Value>

      <DataTemplate>

        <Grid>

          <Root:EditableContentControl Content="{Binding HeaderText, Mode=TwoWay}" />

      </Grid>

    </DataTemplate>

  </Setter.Value>

 </Setter>

</Style>
