            }
             
                BindComboBox();
                //lblMessage.Text = string.Empty;

protected void billingRadGrid_OnNeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            billingRadGrid.DataSource = GetGridTable();
        }
        public DataTable GetGridTable()
        {
            Decimal amount_from;
            if (!Decimal.TryParse(amountFromTb.Text, out amount_from))
            {
                amount_from = 0;
            }
            Decimal amount_to;
            if (!Decimal.TryParse(amountToTb.Text, out amount_to))
            {
                amount_to = 0;
            }
            Decimal duration_from;
            if (!Decimal.TryParse(durationFromTb.Text, out duration_from))
            {
                duration_from = 0;
            }
            Decimal duration_to;
            if (!Decimal.TryParse(durationToTb.Text, out duration_to))
            {
                duration_to = 0;
            }
            string dateFrom = DateFromTb.Text;
            DateTime dateF = DateTime.ParseExact(dateFrom, "yyyy-MM-dd", null);
            string dateTo = DateToTb.Text;
            DateTime dateT = DateTime.ParseExact(dateTo, "yyyy-MM-dd", null);
            DataController dc = new DataController();
            BillingDetail bill = new BillingDetail();
            bill.accountNumber = "12004572";

            bill.toDate = dateT;
            bill.amountFrom = Convert.ToDecimal(amount_from);
            bill.amountTo = Convert.ToDecimal(amount_to);
            bill.durationFrom = Convert.ToDecimal(duration_from);
            bill.durationTo = Convert.ToDecimal(duration_to);
            bill.traficType = trafictypeCombo.SelectedItem.Text;
            bill.terminateState = stateNameTb.Text;
            bill.number = bTNComboBox.SelectedValue;
            bill.lineType = lineTypeComboBox.SelectedItem.Text;
            bill.dialedNum = Convert.ToString(dialedNumber.Text);
            DataTable dtBill = dc.GetUsageDetail_bill(bill);
            if (dtBill.Rows.Count > 0)
            {

                billingRadGrid.Visible = true;
                lblMessage.Text = string.Empty;
                lblMessage.Visible = false;
            }
            else
            {

                lblMessage.Visible = true;
                billingRadGrid.Visible = false;
                lblMessage.Text = "No Records To Display";
                lblMessage.ForeColor = Color.Red;
            }
            return dtBill;

Hi Mukul,

If you want to hide the Label control on the initial page load you can use the following code within the Page's PreRender event:

protected void Page_PreRender(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        lblMessage.Visible = false;
    }
}

Another approach would be to add the above condition at the end of your GetGridTable method.

Hope this helps.
