            {
                IList<AreaData> areaSearch = new List<AreaData>();
                areaSearch = areaManager.GetDestinations();
                cmbMasterInfoDestination.DataSource = areaSearch;
                cmbMasterInfoDestination.DataTextField = "Name";
                cmbMasterInfoDestination.DataValueField = "ID";
                cmbMasterInfoDestination.DataBind();

                RadComboBoxItem cmbParentArea = new RadComboBoxItem();
                cmbParentArea.Text = " ";
                cmbMasterInfoDestination.Items.Insert(0, cmbParentArea);
            }
            catch (Exception ex)

        /// <summary>
        /// Load the Sub Area Details From Database
        /// </summary>
        /// <param name="o">Destination ID</param>
        /// <param name="e"></param>
        protected void cmbMasterInfoDestination_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            JSSessionHandler.SetSessionValue("PropertyDestination", "5");
            if ((cmbMasterInfoArea.SelectedIndex != 0) && (cmbMasterInfoDestination.SelectedIndex != 0))
            {
                IList<AreaData> subAreaData = new List<AreaData>();
                subAreaData = areaManager.GetSubArea(Convert.ToInt64(cmbMasterInfoDestination.SelectedValue));
                cmbMasterInfoArea.DataSource = subAreaData;
                cmbMasterInfoArea.DataTextField = "Name";
                cmbMasterInfoArea.DataValueField = "ID";
                cmbMasterInfoArea.DataBind();

                RadComboBoxItem cmbSubArea = new RadComboBoxItem();
                cmbSubArea.Text = " ";
                cmbMasterInfoArea.Items.Insert(0, cmbSubArea);
            }

            if ((cmbMasterInfoDestination.SelectedIndex == 0) || (cmbMasterInfoDestination.SelectedIndex == -1))
            {
                cmbMasterInfoArea.Items.Clear();
                cmbMasterInfoLocation.Items.Clear();
            }

        }

        /// <summary>

            {
                IList<AreaData> locationData = new List<AreaData>();
                locationData = areaManager.GetChildArea(Convert.ToInt64(cmbMasterInfoArea.SelectedValue));
                cmbMasterInfoLocation.DataSource = locationData;

                cmbMasterInfoLocation.Items.Insert(0, cmbLocation);
            }

            else
            {
                cmbMasterInfoLocation.Items.Clear();
            }
        }
