Question

How do I prevent the caret going to the next line in a text box when the 'ENTER' key has been pressed? In other words how to disable the 'ENTER' or 'RETURN' key in a text-box?

You can write the OnKeyDown event. you can use the e.SuppressKeyPress to tell .NET that you handle the key. Something like this:

if (e.KeyCode == Keys.Enter) {
    e.SuppressKeyPress = true;
}

+1 for useful information for the general case even if it's not the best approach for this particular scenario – Davy8 Mar 13 '09 at 18:46
WOW fast reply... this is way better than other forums (don't want to say which ones) where people insult people who ask questions. Thanks, thanks. – Mar 13 '09 at 20:27
KeyPressEventArgs doesn't contains SuppressKeyPress... I am using OnKeyPress event – Mar 13 '09 at 20:30
If you want to suppress de key you would have to use OnKeyDown – Jedi Master Spooky Mar 13 '09 at 23:44

Take a look at TextBox.AcceptsReturn.

is there a way to do this on a richtextbox? – Mar 13 '09 at 20:32
I am afraid not. But you can override OnKeyDown as Jedi Master Spooky suggests. – Jakob Christensen Mar 14 '09 at 07:14
