c textbox validating event-43

In a Win Form I'm doing initial validation in the Form. To make the code short only three fields are shown in the code.

So before saving data, I want to validate whether all the required fields are filled (Text Boxes) by the user. I would rather use a generic function that would be passed each control on the form and based on the type of the control, separate validation logic would be written.

For example, you could display an error message, change the field’s background color, or at least beep to let the user know that focus did not leave the field because something is wrong. The event triggers even if the user tries to close the form.

That means the user cannot close the form unless the field passes validation.

You do not have to disable the Form’s Auto Validate property.
