Bring a window to the front in WPF

myWindow.Activate();

Attempts to bring the window to the foreground and activates it.

That should do the trick, unless I misunderstood and you want Always on Top behavior. In that case you want:

myWindow.TopMost = true;

I have found a solution that brings the window to the top, but it behaves as a normal window:

if (!Window.IsVisible){    Window.Show();}if (Window.WindowState == WindowState.Minimized){    Window.WindowState = WindowState.Normal;}Window.Activate();Window.Topmost = true;  // importantWindow.Topmost = false; // importantWindow.Focus();         // important

In case you need the window to be in front the first time it loads then you should use the following:

private void Window_ContentRendered(object sender, EventArgs e){    this.Topmost = false;}private void Window_Initialized(object sender, EventArgs e){    this.Topmost = true;}

Or by overriding the methods:

protected override void OnContentRendered(EventArgs e){    base.OnContentRendered(e);    Topmost = false;}protected override void OnInitialized(EventArgs e){    base.OnInitialized(e);    Topmost = true;}
