ข้อมูลใน gridview โชว์แล้ว แต่ถ้าหากเรา insert ข้อมูลลงไปใหม่ ทำยังไงให้มัน refrash ข้อมูลใหม่มาโชว์ทันที

    Sub myGridView_RowCommand(source As Object, e As GridViewCommandEventArgs)
		If e.CommandName = "Add" Then
            '*** CustomerID ***'
            Dim txtCustomerID As TextBox = CType(myGridView.FooterRow.FindControl("txtAddCustomerID"), TextBox)
            '*** Email ***'
            Dim txtName As TextBox = CType(myGridView.FooterRow.FindControl("txtAddName"), TextBox)
            '*** Name ***'
            Dim txtEmail As TextBox = CType(myGridView.FooterRow.FindControl("txtAddEmail"), TextBox)
            '*** CountryCode ***'
            Dim txtCountryCode As TextBox = CType(myGridView.FooterRow.FindControl("txtAddCountryCode"), TextBox)
            '*** Budget ***'
            Dim txtBudget As TextBox = CType(myGridView.FooterRow.FindControl("txtAddBudget"), TextBox)
            '*** Used ***'
            Dim txtUsed As TextBox = CType(myGridView.FooterRow.FindControl("txtAddUsed"), TextBox)

            strSQL = "INSERT INTO customer (CustomerID,Name,Email,CountryCode,Budget,Used) " & _
            " VALUES ('" & txtCustomerID.Text & "','" & txtName.Text & "','" & txtEmail.Text & "' " & _
            " ,'" & txtCountryCode.Text & "','" & txtBudget.Text & "','" & txtUsed.Text & "') "
            objCmd = New OleDbCommand(strSQL, objConn)
            objCmd.ExecuteNonQuery()

            BindData()
        End If
    End Sub
