Say Form1 has Text Box, Form1 is loaded modalessand Form2 is loaded Modaless but I want to run the Text Box Validating event.thanks,.
This eliminates the possibility the end-users will incorrectly enter the values.
Some checks are business rules and thus conceptually they must be done in the business layer of the multi-layer application or in the server-side of a client/server application.
But the key components, which the end-users interact with, are those which reside in the presentation layer.
In Win Forms I could handle the Validated event to do something after the user changed text in a Text Box.
Unlike Text Changed, Validated didn't fire for every character change; it only fired when the user was done.
