Question

I want to make a WPF Window that behaves like a context menu.

So, for instance – when I show the wpf window, I want it to be the topmost window and from there on out, if the user clicks anything outside of that window I want the window to be hidden again.

So far I have tried quite a few techniques but the only one that I found that kinda works is shown here. It works the very first time but never again after that:

public TheWindow() {     InitializeComponent();     this.Topmost = true; }  void ShowMe() {     this.Show();     this.CaptureMouse(); }  void Window_MouseDown(object sender, MouseButtonEventArgs e) {     /// TODO: Check if they clicked outside the window here!     this.ReleaseMouseCapture();     this.Hide(); } 

I also tried just handling the Deactivated event, but it also only works the first time for some reason.

Is PopUp not sufficient for your needs? It has a StaysOpen property that lets it act like you describe.
