Question

I have this in my page:

<asp:DropDownList ID="membros" runat="server">
</asp:DropDownList>

and in the code behind, I have this:

        protected void Page_Load(object sender, EventArgs e)
        {
            members.Items.Clear();
            members.Items.Add(new ListItem("Choose...", ""));

            foreach (DataRow item in com.Execute("select * from tableMembers").Rows)
            {
                 members.Items.Add(new ListItem(item["name"].ToString(), item["id_user"].ToString()));
                 contForeach++;
            }
        }

and when I try to get the value from SelectedIndex I can’t because he always get me 0 independently of what index I choose.

Answer 1

put that in if(!IsPostBack) so that it can load the dropdown at first time the form loads,right now it is loading everytime the page loads so your missing your selection.

      if(!IsPostBack)
      {
        members.Items.Clear();
        members.Items.Add(new ListItem("Choose...", ""));

        foreach (DataRow item in com.Execute("select * from tableMembers").Rows)
        {
             members.Items.Add(new ListItem(item["name"].ToString(),           item["id_user"].ToString()));
             contForeach++;
        }
     }
