validation control

Shawn

In my project, there are 2 dropdown lists. The user can select either one of
them or both to start search.
Can anyone tell me how to validate these 2 fields? Can current VB.Net
validation control handle the situation?
Thanks.

Hi Shawn,

What validation rules do you need to enforce?

I need Required Field Validator. If either of these 2 fields are filled,
then the validation is passed.
Any idea? Thanks.

Hi Shawn,

Because the dropdown lists are not _both_ required, you can't use required field
validators. But you could use a custom validator. If you want client-side
validation as well as server-side, you would need to set the
ClientValidationFunction to the name of a client-side javascript--which you
would need to write yourself (as well as writing the server-side validation code
for the ServerValidate event handler).
