You can find more information about the GridView
class and its members in online MSDN library http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.aspx
. Also, there are a lot of examples demonstrating how use the GridView
control for displaying the values from the database.
About using of ADO.NET
I would recommend this article http://msdn2.microsoft.com/en-us/library/Aa302325.aspx
If your table for the users is used by the Membership
provider, you could use some of the Membership
methods getting the necessary information from the data source.
Hope this helps.
