C#: How to make pressing enter in a text box trigger a button, yet still allow shortcuts such as "Ctrl+A" to get through?

Question

Sorry for the long title, but I couldn't think of another way to put it.

I have this:

    private void textBoxToSubmit_KeyDown(object sender, KeyEventArgs e)     {         if (e.KeyCode == Keys.Enter)         {             buttonSubmit_Click((object)sender, (EventArgs)e);         }     } 

... in order to make pressing enter in the text box trigger the "submit" button. However, this also prevents shortcuts from going through. (not quite sure what it has to do with that, maybe only multi-key combos?)

ShortcutsEnabled is set to true.

Thanks in advance!

Answer 1

Can you not use AcceptButton in for the Forms Properties Window? This sets the default behaviour for the Enter key press, but you are still able to use other shortcuts.

Answer 2

If you want the return to trigger an action only when the user is in the textbox, you can assign the desired button the AcceptButton control, like this.

    private void textBox_Enter(object sender, EventArgs e)     {         ActiveForm.AcceptButton = Button1; // Button1 will be 'clicked' when user presses return     }      private void textBox_Leave(object sender, EventArgs e)     {         ActiveForm.AcceptButton = null; // remove "return" button behavior     }
