How to show an empty GridView when DataSet is datasource?

[JB]

Hello

The datasource for my GridView is a DataSet. When the C# ASP.NET web
page first comes up an empty GridView should appear and then when based on
what selection the user is makes on a different control on the web page then
the GridView will be populated. My question is:

Using this DataSet how can I show an empty GridView when the web page shows?
