Triggering "KeyDown" instead of "Click" on a button by pushing "Enter."

[Curtis Rutland]

OK, I have a question. I have a problem. I'm trying to catch all KeyDown events on a button, but the problem is when I press the "Enter" key, the button's "Click" event is triggered, not the "KeyDown" event. Or if it is, it isn't being caught by the handler.

Is there a way to disable the button being clicked by pushing Enter?

Well, I discovered a workaround. I wanted to capture the "Enter" event regardless of the focus being on the button or the form.

What I did was force the focus to the form when a button was focused on.

I'd still like to know if anyone knows a better way.

Form has an "AcceptButton" property which sets the default action when Enter is pressed, and needs to be a button. (There is also a CancelButton property for when Escape is pressed.

Not sure if that helps, and not even sure if you can set it to null, but sounds as if the button in question is being set as the Form's AcceptButton.

Also, this quote from Control.KeyDown:

Certain keys, such as the TAB, RETURN, ESCAPE, and arrow keys are handled by controls automatically. To have these keys raise the KeyDown event, you must override the IsInputKey method in each control on your form. The code for the override of the IsInputKey would need to determine if one of the special keys is pressed and return a value of true.

I think that overriding IsInputKey is going to do the trick. I'll try it out. Thanks.
