I am working on a small custom control called MyControl and
I wish the control to initalizes and redraws itself once IsExpanded set
to TRUE but
before I proceed to next step in my code.
MyControl containers
an Expander and
a Button.
When Button clicked
I set IsExpanded to
true and in the next step I immediately try to find the TextBox which
is inside Expander.
But I cannot find it because MyControl is
not up to date. When I click again I find the TextBox because then in the meanwhile the wpf had enough time to update everything.
So I wish to force MyControl when
setting IsExpanded to true to init/load control template and redraw itself before I proceed to next step which is in my case finding the TextBox.
