    Is there a "best practice" document/site for control validation in a Windows Forms application?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.This solution works well especially if you have several forms to validate.Is there a simple way of triggering validating/validated event on the button? I tried placing textbox on the form and tabbing between button and textbox, but neither of those events get triggered.
