Drag WPF Popup control

Question

the WPF Popup control is nice, but somewhat limited in my opinion. is there a way to "drag" a popup around when it is opened (like with the DragMove() method of windows)?

can this be done without big problems or do i have to write a substitute for the popup class myself? thanks

Answer 1

There is no DragMove for PopUp. Just a small work around, there is lot of improvements you can add to this.

<Popup x:Name="pop" IsOpen="True" Height="200" Placement="AbsolutePoint"  Width="200">
   <Rectangle Stretch="Fill" Fill="Red"/>            
</Popup>

In the code behind , add this mousemove event

   pop.MouseMove += new MouseEventHandler(pop_MouseMove);

   void pop_MouseMove(object sender, MouseEventArgs e)
    {
        if (e.LeftButton == MouseButtonState.Pressed)
        {
            pop.PlacementRectangle = new Rect(new Point(e.GetPosition(this).X,
                e.GetPosition(this).Y),new Point(200,200));

        }
    }
