Delete link in datagrid not working

I am trying to add a delete link button to a daragrid in asp.net 1.1.  I have the link button in and code from MSDN that looks like it gets intot he correct position of datagrid when I do a response.write index it looks at the correct rows.  But my delete functionality does not work.  How can i delete that row from the table where the StrRecordNumber is equal to itself.

THIS IS MY LINK BUTTON IN DATAGRID

<asp:TemplateColumn HeaderText="Delete">
<ItemTemplate>
<asp:linkbutton id="lnkDelete" runat="server" text="Delete" commandname="Delete"></asp:linkbutton>
</ItemTemplate>
</asp:TemplateColumn>

THIS IS MY CODE BEHIND THAT GETS AT THE DATAGRID ROW.
Private Sub DataGrid1_DeleteCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs)Handles myDataGrid.DeleteCommand

 Dim index As Integer
 index = e.Item.ItemIndex

        insertUpdateDelete("delete table1 where strRecordNumber = '" & ID & "'")
Insertupdate delete calls out my connectionstring from my common.vb file.
        myDataGrid.DataBind()

    End Sub
