i am already doing like this :

protected void lstLotBided_SelectedIndexChanged(object sender, EventArgs e)
{
txtsaleprice.Text = "People Records : " + lstLotBided.Items.Count.ToString();

if ((lstLotBided.Items.Count > 0 && lstLotBided.SelectedIndex >= 0))
{
dt = objEmd.SelectSale_Price(lstLotBided.SelectedValue);
double tempsaleprice = 0;
for (int i = 0; i < lstLotBided.Items.Count; i++)
{
if (lstLotBided.Items[i].Selected)
{
tempsaleprice = tempsaleprice + Convert.ToDouble(lstLotBided.Items[i].Text);

}
}
txtsaleprice.Text = tempsaleprice.ToString();
}
else
{
txtsaleprice.Text = "";
}
}
