Are there some samples for new PopupPlacement class? I tried to use it in a control template, but failed.

What's wrong with following code?

<telerikControls:PopupPlacement x:Key="RadMenuPopupPlacement"

                                 Placement="Top">

 

 

</telerikControls:PopupPlacement>

<Popup x:Name="PART_Popup" telerikControls:PopupPlacement.PopupPlacement="{StaticResource RadMenuPopupPlacement}" >

Hello Leon,

PopupPlacement class is used in Silverlight to workaround the missing features of Microsoft Popup control compared to the one from WPF. For example there is no built-in boundary detection, no Placement property, no PlacementTarget property, etc.
Its use is very simple. You attach it on a popup instance and bind all needed properties. For example if you use it in ControlTemplate you have to bind PopupPlacement.IsOpen to some Boolean property of the control (probably using TemplateBinding or Binding with RelativeSource=Self).
You can also set Placement and PlacementTarget and that's it.

Here is a simple usage:
<Popup>
   <telerik:PopupPlacement.PopupPlacement>
      <telerik:PopupPlacement StaysOpen="False" Placement="Bottom" IsOpen="{TemplatedBinding IsOpen}"/>
   </telerik:PopupPlacement.PopupPlacement>
   <!-- Popup child here -->
</Popup>

Let us know if you need more information.
