I know that this question is old, but I don't quite understand why the accepted answer has received up votes... or why it was accepted... it doesn't really answer the question, or provide a solution and answers posted these days that are that short are almost always down voted and/or deleted by the community. Ah well, I guess it was posted in different times.
Either way, as old as it is, I have a possible solution for anyone who may come across this post in the future. You can simply handle the Window.Deactivated
Event and/or the Application.Deactivated
Event. The Window.Deactivated
Event occurs when a window becomes a background window and the Application.Deactivated
Event occurs when an application stops being the foreground application.
The idea is to set the relevant TopMost
property to true
each time your application or Window
loses focus:
private void Window_Deactivated(object sender, EventArgs e)
{
// The Window was deactivated
this.TopMost = true;
}
It's worth noting that other developers can also use this technique, so this doesn't guarantee that your Window
will always remain on top, but it works for me and the situation is still certainly improved by using it.
