Secondly, I tried this on a page and could not recreate. This is all i have: <asp:ListBox ID="lsbTest" Runat="server" AutoPostBack="True"></asp:ListBox> private void Page_Load(object sender, System.EventArgs e) { if(!Page.IsPostBack) for(int i=0;i<5;i++) { ListItem item = new System.Web.UI.WebControls.ListItem("bob" + i.ToString(), i.ToString()); lsbTest.Items.Add(item); } // Put user code to initialize the page here } private void lsbTest_SelectedIndexChanged(object sender, System.EventArgs e) { Response.Write(lsbTest.SelectedIndex); } and it's (0 - giving me the value of the item that i did click. See if you can get this to work and maybe go from there?

I have created a list box and I populated it with text and values, but when I select an item from the list, the selected index does not change. I have tried multiple times, but each time the selected index does not change. I will post the list box definition and the c# code I am using below. I have gotten the code to execute the ListBox1_SelectedIndexChanged method, but the ListBox1.selectedIndex is always -1. Any help would be appreciated. ListBox Definition: <asp:ListBox id="ListBox1" style="Z-INDEX: 101; LEFT: 184px; POSITION: absolute; TOP: 168px" runat="server" Width="336px" AutoPostBack="True"></asp:ListBox> c# code: private void Page_Load(object sender, System.EventArgs e) { ListBox1.DataSource = LoadGames(); ListBox1.DataTextField = "GameName"; ListBox1.DataValueField = "GameNumber"; ListBox1.DataBind(); } public SqlDataReader LoadGames() { SqlCommand myCommand; SqlDataReader myDataReader; sqlConnection1.Open(); //prepare sql statements myCommand = new SqlCommand("SELECT * FROM Games WHERE NumberOfPlayers < MaxPlayers", sqlConnection1); myDataReader = myCommand.ExecuteReader( CommandBehavior.CloseConnection); return myDataReader; } private void ListBox1_SelectedIndexChanged(object sender, System.EventArgs e) { Label1.Text = "Fired"; } Fri, 11 Nov 2005 03:57:36 GMT http://dotnutz.tribe.net/thread/ef291caa-7aab-4604-b199-50e5b974aa0d#ef72f9df-8983-4601-a740-98a028f8a51f Scott 2005-11-11T03:57:36Z
