Hello,

Is it possible to display a Popup that does not overlap with content outside of it's parent RadPane?

I have played around with the ZIndex but with not luck, the Popup is always top most.

I'm building a custom control that has a DropDown component, which I'm using the Popup control to represent. The problem is when the width of a RadPane is less than the width of the Popup the DropDown spills over into the Document Host area, which looks very strange. Ideally I want the Popup to clip and stay within the bounds of the RadPane. Here's a screenshot:

                        <Popup x:Name="Popup" Canvas.ZIndex="-1000">  
        
                            <Border x:Name="PopupBorder" Canvas.ZIndex="-1000"                          
        
                                    Background="{TemplateBinding Background}"   
        
                                    Height="Auto"   
        
                                    HorizontalAlignment="Stretch"                           
        
                                    BorderBrush="{TemplateBinding BorderBrush}">   
        
                                <ItemsPresenter /> 
        
                            </Border> 
        
                        </Popup>

Any help appreciated,

Cheers,
James.
