[RESOLVED] [2.0] Always trigger AcceptButton even when another button has focus

I have a Windows form and a button that should always be triggered whenever the user presses Enter. I can set the AcceptButton property but if another button is clicked and keeps the focus, then this does no good.

Is there a way to always click a certain button whenever the Enter key is pressed?

In your form's keydown event, check to see if e.keycode = keys.enter. Then call Button5_Click()

That only works when the form is first created and nothing has focus. If a button is ever clicked and gets focus, every Enter key press triggers the button click event.

It's not possible with a standard Button. Even if you set the form's KeyPreview property to True the form will not raise keyboard events for the Enter key when a Button has focus. I'm guessing that you would have to inherit the Button class and reverse the result of the IsInputKey function for the Enter key. I haven't checked but I'm guessing it returns True and you'd have to return False instead.

OOh.. yes.

Let's see what can be found...

Code:

---

      protected override bool ProcessDialogKey(Keys keyData)
        {
            if (keyData == Keys.Enter)
            {
                button3_Click(null, null);
                return false;

            }
            else
            {
                return base.ProcessDialogKey(keyData);
            }
           
        }

        private void button3_Click(object sender, EventArgs e)
        {
            Console.WriteLine("Button3");
        }

Rather than this:

CSharp Code:

button3_Click(null, null);

you should do this:

CSharp Code:

this.button3.PerformClick();
