How to hide columns in an ASP.NET GridView with auto-generated columns?

Question

GridView1.Columns.Count is always zero even SqlDataSource1.DataBind();

But Grid is ok

I can do

for (int i = 0; i < GridView1.HeaderRow.Cel         


        

Answer 1

You have to perform the GridView1.Columns[i].Visible = false; after the grid has been databound.
