I can't take it any longer... Can someone pleaseeeee help me. I have included my code below. I have searched everything and read many articles but I still don't get it. So please no reaction in the sense; you must create your controls in page_load, you must recreate your controls in the onpageinit, preserve viewstate, etc. because I have seen all those matters, many many times. My guess is that I just miss a tiny bit... On a webform I have a placeholder and in codebehind this placeholder is filled with 2 dropdownlists and two buttons. The two lists are filled with data from a dbase. When a user clicks one button an item is transfered from one list to the other, vice versa. What happens in code below is that I have to click a button twice to have an item move. Actually the first time when I click the button the item is transfered but the list wont refresh, while I regenerate the listboxes in my on page init (i tried the on postback as well). When I do a response.redirect to the same page it works fine but that shouldn't be the way to go. Imports System.Data.SqlClient Imports System.Data Partial Class Beheer_viewstate Inherits System.Web.UI.Page Dim bID As Integer Sub Page_Init(ByVal s As Object, ByVal e As EventArgs) Handles MyBase.Init Session("boekingID") = 105 bID = 105 dynamiccontent() End Sub Sub dynamiccontent() Dim conn As New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("MyProvider")) conn.Open() 'ongeboekte extras per reiziger Dim get_boeker_ongeboekte_extras As New SqlCommand("get_boeker_ongeboekte_extras", conn) get_boeker_ongeboekte_extras.CommandType = CommandType.StoredProcedure get_boeker_ongeboekte_extras.Parameters.AddWithValue("@boekerID", bID) get_boeker_ongeboekte_extras.Parameters.AddWithValue("@boekingID", Session("boekingID")) Dim rdr_get_boeker_ongeboekte_extras As SqlDataReader = get_boeker_ongeboekte_extras.ExecuteReader() Dim extras As New ListBox extras.ID = "lbx_extras" & bID extras.DataSource = rdr_get_boeker_ongeboekte_extras extras.DataValueField = "extraID" extras.DataTextField = "naam" extras.EnableViewState = "true" extras.DataBind() rdr_get_boeker_ongeboekte_extras.Close() 'geboekte extras Dim get_boeker_geboekte_extras As New SqlCommand("get_boeker_geboekte_extras", conn) get_boeker_geboekte_extras.CommandType = CommandType.

That is a little bit too vague... I think it should be solved with the creation of a datatable somehow but dunno more than that. With only a loop I still have the problem that the textboxes have a name: textbox1, textbox2, etc.

lstland.SelectedIndex = -1 after the databind should do the trick... or otherwise you could add an extra field on top before the drodown is generated f.e. "select an item"

I have a simple question wich probably can be easily answered but I'm clueless. On a webform people can invite friends (lets say 10). So I have 10 times dropdown: Mr. / Mrs., 10 times: Tetxtbox; firstname and 10 times: Textbox emailadres. I want to insert these in tabel tblfriends. Before I insert I would like to do some validation to see if the friend allready exists in the database, sent an email to the person etc. But that is not the point really. Would I end up writing ten insert queries with lstmrmrs1, txtfirstname1, txtemal1 then lstmrmrs2, txtfirstname2, txtemal2, etc. up to 10 ? I have googled quite a bit but can't find a hint.
