.NET Forum / Windows Forms / WinForm Controls / February 2005How do you "cancel" keystrokes in a WinForms control?
Hi everyone, I'd like to be able to "cancel" keystrokes in a custom textbox (or combobox) so that the user is unable to enter too many characters for the underlying databound field. How? Thanks. BBM Does the "MaxLength" property work in your situation?

I guess I looked in detail at the "Control" properties but not the "TextBox" or "ComboBox" ones. Pretty embarassing. Thanks for the tip.

If that is the case, then the TextBox and ComboBox should do that already.
