I am new to ASP.NET and VS2005 and am trying to use the GridView Control.I have a stored procedure in my DB which works fine and produces the results I want when running the script in SQL Server Manager. When I put in the data in the wizard for creating the GridView in VS2005 I only get a result if I put in values for all parameters, if one is empty there is no results.But when I try it on the webpage I have created where the GridView is supposed to use 3 parameters from the Querystring it doesn't show any results. Can anyone help a newbie with this? Thank you.
