I need it because when you come into the page the first time the grid should be loaded with the default selection of 250 pending cases. Then you can select one of the buttons to go to another view which is populated in the gridview.
I got it to work by adding this to page load:
GridView1.Columns(2).Visible =
False
GridView1.Columns(3).Visible =
False
GridView1.Columns(4).Visible =
False
