If this is databound, its possible that the binding was lost during postback. On what event did you put this code?

Solution 1

here

grdAvailableStuff.Columns[2].Visible = false;

Means your are hiding 3rd column of grid view.

Make sure that grid view renders with 3 or more than 3 columns.

Try this

C#

protected void grdAvailableStuff_RowCreated(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header)
           {
               e.Row.Cells[1].Visible = false;
              
           }
       }
