Question

I am creating a window object globally and display it only when it is necessary, most of the time window will be in invisible mode. I have some work to do whenever the window is visible. can any one please tell me which message should i override to put the code which is supposed to execute when a window.show method is called?

Answer 1

IsVisibleChanged should do what you want.

private void Window_IsVisibleChanged(object sender, DependencyPropertyChangedEventArgs e)
{
  if ((bool)e.NewValue == true)
  {
     //Do what you need here
  }
}
