Get width of element of auto width

I am trying to get the Width of a StackPanel. I tried:

double width = stk_main.ActualWidth;

which gave zero and it shouldnt be. Also:

double width = stk_main.Width;

which gives NaN because width set to auto previously. So how can I get the width?

You could attach to the Loaded event of the StackPanel as the layout pass will have completed by this point and the ActualWidth will be set.

You can use sizeChanged, but it doesn't work when the stack panel you used not change size.

private void stk_main_SizeChanged(object sender, SizeChangedEventArgs e)
{
    double yourWidthNow = e.NewSize.Width;
}

Hope it can give you some help...
