Get WPF control height when it is set 'Auto'

Question

I need get a WPF control height for calculate my next control margin top, but when I try get control height with textbox1.height , this is return 'Auto' and not numbers

What can I do for get control height, when it is set 'Auto'?

Answer 1

You should try this:

textBox1.ActualHeight

Remarks (by @Viv)

just make sure when you query for textBox1.ActualHeight, you do it once the control is Loaded. You're going to get 0.0 if you check ActualHeight before it's setup properly
