Hi all, 
This is my first post here so forgive me if I missed a forum rule in posting this. I recently took over management of an intranet webserver built using asp.net 4.0. I need to create a textbox where users can enter an ID, but I want to check their input against a sql database table and return something like "This is not a valid ID" if the user inputs something that is not one of the 100 IDs. The site is built using visual basic. I'm fairly new to C# and VB, and ASP in general, so I'm at a bit of a loss. Any links or literature would be great. 
Thanks!
