Hide column of an autogenerated gridview with one templatefield

Question

I have autogenerated columns here from visitid and so on. The first column however was a templatefield. now I wanted to hide VisitID. I tried this code but it didn't work. I am using vb as my codebehind

e.Row.Cells(1).Visible = False

Answer 1

I have tried several ways but also ended with this code and it worked finally I just added a condition. I'm sorry maybe I lacked information. I had a pagination in the gridview.. Here was my working code.

Protected Sub Gdvisitor_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles Gdvisitor.RowCreated
    If (e.Row.Cells.Count > 1) Then
        e.Row.Cells(1).Visible = False
    End If
End Sub

At first it was "....cells.count < 0" and that didn't work the index was still out of range but when I changed it to 1. It worked. I think the pagination has something to do with it. I'm not sure though... Thank you for all the help
