Hi everybody... I need all of urs help.

I need to validate a dropdownList in asp.net. From the list of items in the dropdown, when a specific item selected i need to give an error notification saying "this item is not valid".

Ex:- letz say these are the names in the list.  "Mark" , "Brayan", "Kate", "Loren"

What i wanna do is when i select "Kate" the error notification should appear in the UI.

Help me soon....

 

Hi, it can be done using Custom Validator. The code is as follows

<Script language="javascript">
function validateDropdownlist(src, args)

    {
     args.IsValid = (args.Value=='Kate');
    }

</Script>

Hope this helps.
