I've got a module where i search for a candidate with his Id and display his name, age..etc..
I've put the details like name , age etc.. in the datagrid.
The search module is working fine.. when a valid candidate Id is entered.
But when an invalid ID is entered... an empty datagrid is displayed.(obviously)
How can i validate for a non existing ID?
Backend used is MS SQL.
I didn't know where to post this thread VB.NET, ASP.NET or SQL! Hope I'm in the right place.
