customvalidator... or?

Hi

I have a page with severeal dropdown lists that get values from a database, and I also add a "select option" to every dropdown list. I would then like to check each dropdown list, so that the user select anything else than the first option "select option". How can I check this?

Custom Validator as you said.
Check if the selected index is not 0.

or use RequiredFieldValidator, and set the Intitial Value to the "Select Option"'s value...

Known is handfull, Unknown is worldfull

vbkris option of using RequiredFieldValidators is the cleanest solution. This will also do client-side validation before posting back to the server. Any time you save a round trip it's a good thing.

For the RFVs to work make sure the "select" options have a text of "select" and a value of "" (empty string). If you don't define both the RFVs will interpert the "select" option as valid.

You can perform client-side validation with the custom validator too. This, with a simple javascript function.
