setting IsOpen=true makes RadContextMenu staying opened

<Rectangle Stroke="Black" StrokeThickness="1" Fill="#DADADA" Height="8" Width="8">
     <Rectangle.Triggers>
       <EventTrigger RoutedEvent="MouseLeftButtonDown">
         <BeginStoryboard>
           <Storyboard>
             <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="IsOpen" Storyboard.Target="{x:Reference ContextMenu}">
               <DiscreteObjectKeyFrame>
                 <DiscreteObjectKeyFrame.Value>
                   <sys:Boolean>True</sys:Boolean>
                 </DiscreteObjectKeyFrame.Value>
               </DiscreteObjectKeyFrame>
             </ObjectAnimationUsingKeyFrames>
           </Storyboard>
         </BeginStoryboard>
       </EventTrigger>
     </Rectangle.Triggers>
     <telerik:RadContextMenu.ContextMenu>
       <telerik:RadContextMenu x:Name="ContextMenu" ShowDelay="0">
         <telerik:RadMenuItem Header="Reset value" />
         <telerik:RadMenuItem Header="Set binding" />
       </telerik:RadContextMenu>
     </telerik:RadContextMenu.ContextMenu>
   </Rectangle>

Click on the rectangle, then click somewhere else and radcontextmenu stays opened.  This way you can open multiple contexmenus simultaneously

This does not happen with regular contextmenu.

Hello Daniel,

We'll check what is causing this behavior, but meanwhile I would suggest you to check this article which is describing how to open RadContextMenu on a specific event. In your case the code will look like this:

<Rectangle Stroke="Black" StrokeThickness="1" Fill="#DADADA" Height="8" Width="8">
    <telerik:RadContextMenu.ContextMenu>
        <telerik:RadContextMenu x:Name="ContextMenu" EventName="MouseLeftButtonDown">
            <telerik:RadMenuItem Header="Reset value" />
            <telerik:RadMenuItem Header="Set binding" />
        </telerik:RadContextMenu>
    </telerik:RadContextMenu.ContextMenu>
</Rectangle>

If you use it this way, RadContextMenu will open only on MouseLeftButtonDown event and it will work as you expect.

Hopefully this helps.
