ASP.net get data from a data connection or GridView

Hi

I am using the following VB code to populate a GridView in ASP.net.
I need the user of my website to be able to use this data. How do I read the data
off the GridView using VB code?
Protected Sub Button_SeeWholeCalendar_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button_SeeWholeCalendar.Click
        '// define a connection to the database
        Dim cs As String = ConfigurationManager.ConnectionStrings("WhatEverNameYouWant").ConnectionString
        cs = cs.Replace("App_Data\GC.accdb", Server.MapPath("App_Data\GC.accdb"))

        Dim cn As New OleDbConnection(cs)

        '// define the sql statement to execute
        Dim cmd As New OleDbCommand("SELECT * FROM [Table1]", cn)

        Try

            '// open the connection
            cn.Open()

            '// execute the sql statement
            Using reader As OleDbDataReader = cmd.ExecuteReader(CommandBehavior.CloseConnection)

                ' While reader.Read()
                '// this loops through all of the returned records
                'Response.Write("blah")
                'End While

                GridView1.DataSource = reader
                GridView1.DataBind()

            End Using


        Catch ex As Exception
            Response.Write(ex.Message)

        Finally
            If cn.State <> ConnectionState.Closed Then
                cn.Close()
            End If
        End Try
    End Sub

Just add a new GridView to the page and, from its Smart Tag, click the Enable Editing checkbox (see attached imge ). This will add a CommandField to the GridView with an Edit button.
