c# - TextBox autocomplete and default buttons

Question

I have a .NET TextBox with AutoComplete feature on the form. The form has also AcceptButton and CancelButton defined. If I try to commit a suggestion with Enter key or close drop down with Esc, my form closes. How can I prevent this behavior?

Answer 1

Do not assign AcceptButton and CancelButton form properties. Set DialogResult in the buttons OnClick event.
