How can I determine if the Backspace has been pressed in the KeyPress event?

c#, keycode, keypress, winforms

Solution

try comparing `e.KeyChar != (char)Keys.Back`, you should cast it to char since Keys is an enumeration

see this: KeyPressEventArgs.KeyChar

Problem

This: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keypress.aspx ...indicates that I should have access to e.KeyCode in the KeyPress event, but I don't seem to. I'm trying to allow only 1,2,3, and backspace: ``` private void textBoxQH1_KeyPress(object sender, KeyPressEventArgs e) { if ((e.KeyChar != '1') && (e.KeyChar != '2') && (e.KeyChar != '3') && (e.KeyChar != (Keys.Back))) { e.Handled = true; } } ``` ...but "e." does not show a "KeyCode" value like the example shows, and trying KeyChar with Keys.Back scolds me with, "Operator '!=' cannot be applied to operands of type 'char' and 'System.Windows.Forms.Keys'" So how can I accomplish this?
