I have a usercontrol which is a VSIX tool window (Visual Studio Extension). I want to get the height and width of the tool window when a button is clicked.

This has proved elusive so far. I tried ActualWidth, ActualHeight, Height, Width, Render size tried doing a Mesaure(double.infinity,double.infinity) and then doing above. I also tried calling UpdateLayout and doing the measurement. The value never changes.

What I have tried:

There are other classes like below. The class I tried the above steps is the class that is derived from UserControl which is used on the Form. The class below are other classes that are typical in a userControl and autocreated when i create a VSIX solution. I am not an expert in the relationships.
