I understand how validated event works with textbox but I don't understand how it's triggered with button on a form.
MSDN doesn't have validated/validating listed in their documentation.
But this doesn't work well if you're trying to make sure a user didn't leave a textbox empty by skipping over it.
In my solution, when the user clicks the submit button for a form, I check each control on the form (or whatever container is specified) and use reflection to determine if a validating method is defined for the control. If any of the validations fail, the routine returns a failure and allows the process to stop.So the user has to actually click inside a text box then click somewhere else for the validation routine to execute.This is fine if your only concerned about the data that is entered being correct.For more information, see the WM_KILLFOCUS topic in the "Keyboard Input Reference" section, and the "Message Deadlocks" section of the "About Messages and Message Queues" topic in the MSDN library at The following code example uses the derived class Text Box and validates an e-mail address that the user enters.This will future proof your code as much as possible and prepare you for any breaking changes down the road to the internals of the Framework.
