I don't do PRISM but I still think you want to get rid of the x:key. Also the / in front of AQUA doesn't look right either. Try removing that as well. "You get that on the big jobs."

Right, But i don't know the number of fields i have.

Using a template like below might help you out.

Something like this; class MyBaseClass { public virtual string methodName() { return "This is base calling"; } } class MyTestedClass: MyBaseClass { public override string methodName() { return "This is the testing value calling"; } } class MyTestedClassMock: MyBaseClass { public override string methodName() { return "Whaahaha, I'm not the real one, just a mock-stand in."; } } //..in the test-bit MyBaseClass someObject = new MyTestedClassMock(); // or new MyTestedClass(); MessageBox.Show(someObject.methodName()); Bastard Programmer from Hell :suss:

Ahh, I see. Well, you need to give the label you are interested in a name, and use TargetName in your style trigger setter to change the style. The actual style you have as the main style should be Button not Label. *pre-emptive celebratory nipple tassle jiggle* - Sean Ewington "Mind bleach!

Have a look here[^] for an example.

OK. Another issue is that this context menu opened on left mouse click on button. But it never enters the can_execute . But when i click Right Mouse Button it does enters can_execute. How to solve it?

Have a look at this http://blog.superuser.com/2011/05/16/windows-7-network-awareness/[^] Explains how MS does it, and how you can set up your own server to check. Good luck :) Computers have been intelligent for a long time now. It just so happens that the program writers are about as effective as a room full of monkeys trying to crank out a copy of Hamlet.

OK. So what will happen if i call an event that is handled in the main thread (not UI thread)?

You need code in your Action that checks to see if the IsCancellationRequested property of the token is True. A guide to posting questions on CodeProject[^] Dave Kreskowiak

The "server" is the one that opens the listener. The "client" is the one that connects with a client socket to the server (where the listener is.) I don't care how you label your app(s). And what I said holds. The client can't close the listener. The client can close the client socket. The server can close the client socket (the one it created based on a listener request.)

If you are using any of the features that were introduced in .NET 4 (e.g. SortedSet), then you need to convert that portion of the code. "WPF has many lovers.
