Disable Enter Key in Textboxes

Question

I am developing a chatting system. And I have a Button to send the text in the text box to the chat log. How am I going to stop the user from press Enter key and to disable the Enter key. I know there are many posts out there like this, but the solutions haven't worked for me.

Metro? WinForms? WPF? Silverlight? Windows Phone? ASP.Net? MonoTouch? — SLaks, Aug 07 '13 at 17:53
textBox1.Attributes.Add("onkeydown", "return (event.keyCode!=13);"); — user2650977, Aug 07 '13 at 18:00
the goal is, if the Enter key is pressed to send the message, not go to a new line? — Jonesopolis, Aug 07 '13 at 18:08
Unlike forum sites, we don't use "Thanks", or "Any help appreciated", or signatures on [so]. See "[Should 'Hi', 'thanks,' taglines, and salutations be removed from posts?](http://meta.stackexchange.com/questions/2950/should-hi-thanks-taglines-and-salutations-be-removed-from-posts). — John Saunders, Aug 07 '13 at 18:11

You can try something like this:-

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

But the user still can press Enter key to sending the text from text box. Can disable the Enter key? – user2650977 Aug 07 '13 at 18:01

I think you do not need to stop the user from pressing enter but instead send the chat to the other person on press of enter.

Also if you have any other shortcuts to be allowed then you can have a look at this C#: How to make pressing enter in a text box trigger a button, yet still allow shortcuts such as "Ctrl+A" to get through?

Using the same you can also block

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

Your question is a little ambiguous to say the least; however, the textbox control has an event called KeyDown : http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keydown.aspx

This way, you can capture whenever Enter is pressed and modify and behavior as needed, here is an example

private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (Keys.Enter == e.KeyCode)
        {
            MessageBox.Show("Enter Was Pressed");
            textBox1.Text = new String(textBox1.Text.Where((ch, i) => i < textBox1.Text.Length - 2).ToArray());
            textBox1.SelectionStart = textBox1.Text.Length;
        }
    }
