Assuming you have the controls themselves, you can use ctrl.ActualWidth, and ctrl.ActualHeight

Hi
Thanks

There is a little problem because it works only if the ctrl is displayed.
Assume there is a button and at the click event i need to get the ctrl.actual width

 Private Sub button1_Click(sender As Object, e As RoutedEventArgs) Handles button1.Click
    
   myctrl.visibilty = = Visibility.Visible
 dim drawobj as classdraw
    drawobj = new classdraw(myctrl.actualheight,myctrl.actualheight)
 end sub

myctrl.actualheight = 0
