I am working on an application where I want to populate a list, have teh user select one of the items and then act on that selection. 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";
}
