C# Textbox Keypress Control Help

I have a standard textbox that I want to perform an action on a keypress. I have this code currently:

private void idTextEdit_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)Keys.Enter/Return)
        {
            e.Handled = true;
            SearchButtonClick(sender, EventArgs.Empty);
        }
    }

The problem is, I have tried both Enter and Return up there which is the reaso开发者_高级运维n for that. It is only firing that check for normal keys that are not like shift, control, etc. How can I design this so that it will pick up and use the enter/return key in the same way?

You should use the KeyDown event instead:

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Return)
    {
        //...
    }
}

If it for some reason has to be KeyPress, you can use (char)13 or '\r' for your check, though I doubt that would work well on a non-Windows OS.

if (e.KeyChar == '\r')

You cannot just cast Keys.Return to a char, because it's a bitflag enum and doesn't just hold the corresponding ASCII code.
