Default Buttoncolums in a Datagrid

Hi all,
i have seruoius problems adding a buttoncolum to a datagrid programmatically.
I added a buttoncolum to the datagrid whitc simply selects the item. At this point i would like have fired the SelectedIndex-Event, but nothing happened !!!

This is my code:

Private Sub Page_Load (...


        DataGrid1.DataSource = myDs
        DataGrid1.DataMember = myDs.Tables(0).TableName.ToString

        Dim colonna As New ButtonColumn()
        colonna.ButtonType = ButtonColumnType.LinkButton
        colonna.HeaderText = "Select"
        colonna.Text = "Select"
        colonna.CommandName = DataGrid1.SelectCommandName
        colonna.DataTextField = myDs.Tables(0).Columns(0).ColumnName.ToString
        colonna.DataTextFormatString = "Sel"

        DataGrid1.Columns.AddAt(myDs.Tables(0).Columns.Cou nt, colonna)



End Sub

Private Sub DataGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.SelectedIndexChanged
        Errlabel.Text = sender.SelectedItem.Cells.Item(0).Text
End Sub

Can anyone help me, please????

Is it necessary to bind the data every time the page loads? You really should only call the binding code when "Not IsPostBack". This might be what's causing the problem.
