hi,
RootItems are generated from Page_Load..
Code Snippet Below............
==================================================
SqlDataAdapter sda = new SqlDataAdapter("SELECT CAM_CGID,CAM_CNAM FROM E_CAT_MST WHERE CAM_CLVL=1", conn);
DataTable dt = new DataTable();
sda.Fill(dt);
RadMenu1.DataSource = dt;
RadMenu1.DataTextField = "CAM_CNAM";
RadMenu1.DataValueField = "CAM_CGID";
RadMenu1.DataBind();

===================================================
===============At the 2nd label the item is loaded from Webservice====================
<Script>
function itemPopulating(sender, eventArgs) {
var item = eventArgs.get_item();
var context = eventArgs.get_context();
context["CAM_CPID"] = item.get_value();

}
</Script>
==================================
===============Telerik Menu=======================
<telerik:RadMenu ID="RadMenu1" runat="server"
OnClientItemPopulating="itemPopulating" Flow="Vertical" Height="500" EnableRootItemScroll="true"
DefaultGroupSettings-Height="300" EnableRoundedCorners="true"

==============================Webservice Code==============================
public RadMenuItemData[] WebServiceMethodName(RadMenuItemData item, object context)
{
      DataTable productCategories = GetProductCategories(item.Value);
List<RadMenuItemData> result = new List<RadMenuItemData>();
foreach (DataRow row in productCategories.Rows)
{
RadMenuItemData itemData = new RadMenuItemData();
itemData.Text = row["CAM_CNAM"].ToString();
itemData.Value = row["CAM_CGID"].ToString();

itemData.ExpandMode = MenuItemExpandMode.WebService;
    result.Add(itemData);
}
return result.ToArray();
}

public DataTable GetProductCategories(string value)
{
DataTable dt = new DataTable();
SqlDataAdapter sda = new SqlDataAdapter("SELECT CAM_CNAM,CAM_CGID FROM E_CAT_MST WHERE CAM_CLVL <> 1 AND CAM_CPID=" + value, conn);
