Floating RadPane don´t show content

[Mirko]

Hi,

I have a problem if a user float a docked RadPane. If the RadPane is docked the content is visible! 

If the user now floatin the RadPane the content of the pane are hidden.

I can´t find the bug in my code. I check my code with the example of the RadDocking SL demo. 

<telerik:RadDocking Grid.Row="1" x:Name="DockingFrame" Close="DockingFrame_Close" >
      <telerik:RadDocking.DocumentHost >
        <telerik:RadSplitContainer>
          <telerik:RadPaneGroup x:Name="MyMap">
            <telerik:RadPane Title="{Binding MapTabHeader}" Header="{Binding MapTabHeader}" telerik:RadDocking.SerializationTag="DocumentPane" TitleTemplate="{StaticResource TitleTemplate}" HeaderTemplate="{StaticResource TitleTemplate}" CanFloat="False" CanUserClose="False">
              <telerik:RadPane.Content>
                <Lab:LabContentControl x:Name="MapContent" Content="{Binding MapViewModel}" Grid.Column="1">
                  <Lab:LabContentControl.ContentTemplate>
                    <DataTemplate>
                      <Views:LabMapView Lab:LabDragAndDropManager.IsDropDestination="True" />
                    </DataTemplate>
                  </Lab:LabContentControl.ContentTemplate>
                </Lab:LabContentControl>
              </telerik:RadPane.Content>
            </telerik:RadPane>
          </telerik:RadPaneGroup>
        </telerik:RadSplitContainer>

Hi Mirko,

We tried to reproduce the issue with the code you provided to us but with no success. The only modifications we made was to replace the Lab:LabContentControl controls with simple TextBox controls.

Could you try to reproduce the issue with only TextBox controls inside the RadPanes and lets us know if the issue persists?

Kind regards,
