Question

I’m new to WPF and have a question among behavior in forms.

I added a key down event to catch a pressed return key.

Now the Problem, there is no visual feedback. Is it possible to let the button look like it got pressed by the mouse?

It should look like i pressed the button via mouse, but instead after pressing return.

If I understand, you want to simulate the visual effect of a button click, so, to achieve this, you have to change the IsPressed property of the button, but is read-only, then, System.Reflection is useful:

on KeyDown event:

typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(btnSimulate, new object[] { true });

and KeyUp:

typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(btnSimulate, new object[] { false });
