How to Disable F11 key

I want to disable the F11 key in my Silverlight application because I don't want a user to switch to full-screen mode.

Or is there a way I can write my code for F11 key event? I tried with key down event , but not working for F10 and F11 and set of other keys .

Silverlight prohibits switching to and from fullscreen mode except when handling a user event (such as clicking a button or link), so there is no way of detecting that a user goes full-screen and then reverting it.

From what I can find in the documentation, there is also no way of preventing an application going fullscreen.

On the other hand, MSDN states that a Silverlight application can only work in two-ways: embedded or fullscreen. So if you embed your application this should not be a problem, because full-screen switching in an embedded Silverlight application will only happen if you set Host.Content.IsFullScreen to true.

I suspect the browser has precedent over the Silverlight plugin.

You could use Javascript to disable key input. Here's a blog post about how: Disable ctrl + n and other ctrl + key combinations in JavaScript
