c# - How to skip Validating after clicking on a Form's Cancel button

Question

I use C#. I have a Windows Form with an edit box and a Cancel button. The edit box has code in validating event. The code is executed every time the edit box loses focus. When I click on the Cancel button I just want to close the form. I don't want any validation for the edit box to be executed. How can this be accomplished?

Here is an important detail: if the validation fails, then

            e.Cancel = true;

prevents from leaving the control.

But when a user clicks Cancel button, then the form should be closed no matter what. how can this be implemented?

Answer 1

If the validation occurs when the edit box loses focus, nothing about the the cancel button is going to stop that from happening.

However, if the failing validation is preventing the cancel button from doing its thing, set the CausesValidation property of the button to false.
