protected void txtvDate_TextChanged1(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            dt = DAL.GenericSP_RS(1, "Sp_GetVehicleTrack", "");
            foreach (DataRow row in dt.Rows)
            {
                foreach (var item in row.ItemArray)
                {
                    DateTime dtc = Convert.ToDateTime(txtvDate.Text);
                    DateTime idt = Convert.ToDateTime(item);
                    if (dtc == idt)
                    {
                        Response.Redirect("VehicleManagement.aspx?idt=" + txtvDate.Text);
                       //lblmsg.Text =  "Record already inserted!";
