Its working but i have binded my listbox with sql values like

if (!Page.IsPostBack)
{
str = "select * from TBL_NM_State where StateId<112";
cmd = new SqlCommand(str, con);
DataSet ds = new DataSet();
da.SelectCommand = cmd;
con.Open();
da.Fill(ds, "TB1");
Lst1.DataSource = ds.Tables[0].DefaultView;
Lst1.DataTextField = "Statename";
Lst1.DataValueField = "Statename";
Lst1.DataBind();

}

if (Lst1.SelectedIndex > -1)
{
Int32 idx = Lst1.SelectedIndex;
}

values are there but could not finding index values after clicking on particular item

( I think my sql values are not a part of items collection)
