Let's say you have a form with textbox control, textbox1.Place an errorprovider control on the form (it is not a visible control).

But the key components, which the end-users interact with, are those which reside in the presentation layer.

Therefore, this is the first place where the validation should be done.

Should this validation be done in the business layer or in the middleware component of a multi-layer application?

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.

So, Instead of writing the code in Got Focus event, write the Code in "Enter" Event.....

Net to Destroy and Re-Create the Controls at runtime...

There is a deep discussion about when, where and how this validation should be done.

Should this validation be done on the client-side or the server-side in a client/side application?

Note that only the Cell Validating event can keep the editor active,when the validation fails and it does not allow the user to exit the cell until a valid value is filled.
