Hi guys,
M facing this problem...The listbox selected value doesn't get set in textbox.

on page load

if (!IsPostBack)
           {
               DataTable _dtusers = _objLog.getUser();
               lstbx.DataSource = _dtusers;
               lstbx.DataValueField = _dtusers.Columns["Username"].ToString();
               lstbx.DataTextField = _dtusers.Columns["name"].ToString();
               lstbx.DataBind();
           }

I have assigned listbox the datasource

and on its selected index change

protected void lstbx_SelectedIndexChanged(object sender, EventArgs e)
{
    for (int i = 0; i < lstbx.Items.Count; i++)
    {
        if (lstbx.Items[i].Selected)
        {
            txtUserName.Text = lstbx.Items[i].Value.ToString();
        }
    }

}

Everything works fine...i have already enabled the viewstate and autopostback property to true..When i debug, it shows no error and also shows that value gets set but the value just doesn't show up in the textbox..

please guide me...
