Is there a way to make a gridview autogenerate columns when its datasource changes its stored procedure?

[Red_Wizard_Shot_The_Food]

I have a gridview on an AJAX update pannel. When the user clicks different buttons the GridViews DataSource changes the stored procedure it uses to query the table. Is there a way to make the gridview autogenerate its columns anew when the datasource changes? as the qeuries differ from one another in only a couple of columns. OR do I have to manauly add and remove all the columns needed after I have changed the stored procedure the DataSource for the GridView will use?
