Capture ESC in textbox

Question

I want to have the Esc key undo any changes to a textbox since it got focus.

I have the text, but can't seem to figure out how to capture the Esc key. Both KeyUp and KeyPressed don't seem to get it.

Answer 1

This should work. How are you handling the event?

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{          
    if (e.KeyCode == Keys.Escape)
    {
       MessageBox.Show("Escape Pressed");
    }
 }

Edit in reply to comment - Try overriding ProcessCmdKey instead:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) 
{
     if (keyData == Keys.Escape && myTextBox.Focused) 
     {
         MessageBox.Show("Escape Pressed");
     }

     return base.ProcessCmdKey(ref msg, keyData);
}
