ChildWindow Positioning

Tue, 07 Jun 2011 11:23:52 +0000

Silverlight ChildWindow is centered over the parent control. I have extended ChildWindow to open it at a specific position.

Positioned ChildWindow

Here is a live demo : childwindow-positioning-demo

And here is the code :

public partial class ChildWindowEx : ChildWindow
{

 Point _pt = new Point(0,0);

 public ChildWindowEx()
 {
 InitializeComponent();
 }

 public ChildWindowEx(Point pt) : this()
 {
 _pt = pt;
 }

 protected override Size ArrangeOverride(Size finalSize)
 {
 Grid grid = Utils.FindChild(this, "ContentRoot");

 if (grid != null)
 {
 grid.Arrange(new Rect(_pt.X, _pt.Y, grid.DesiredSize.Width, grid.DesiredSize.Height));
 return finalSize;
 }

 return base.ArrangeOverride(finalSize);
 }
}
