Find control position on canvas

I have a Canvas which contains a few Textblocks and I need to find the top and left corner points that were assigned in the XAML Document. How can I get those two properties?

When I loop through the Framework Elements on the Canvas I can't seem to find those to properties listed.

Solution

  • Here some examples how to get the values:

    foreach(FrameworkElement fe in canvas.Children){

   // example 0
   double top=(double)fe.GetValue(Canvas.TopProperty);
   double left=(double)fe.GetValue(Canvas.LeftProperty);

   // example 1
   double top1=Canvas.GetTop(fe);
   double left1=Canvas.GetLeft(fe);

}
