Hi,

In my code behind, iam fetching some data from webservice and manupulating it as per need and storing
into hashtable.

Now i wanted to display that hashtable data inside RADListView in the form of rows, The RadListView is under NestedViewTemplate of RadGrid.
I tried it to display, but data is not showing when i try to view in browser.
In the Control page (ascx):
<NestedViewTemplate>
<asp:Panel ID="panel2" runat="server" >                           
         <telerik:RadListView ID="RadListView2" runat="server">
                        
 <td >
                                 Address:<%# Eval("ADDRESS")%>
                         </td>
  <td>
                                <!-- Need to display----->
                       <asp:Label ID="Label11" runat="server" Text='<%#keysLst3[0].ToString() %>'>
                       </asp:Label>                                                
                 </td>
         </telerik:RadListView> 
</asp:Panel>
</NestedViewTemplate>

in Code behind (cs.ascx):

 protected void PopulateServices()
        {
   public ArrayList keysLst3 = null;
            public ArrayList list = null;
            public ArrayList actuaList = null;
            public Hashtable table = null;      

        public static ArrayList GetKeys(Hashtable table)
        {
            return (new ArrayList(table.Keys));
        }

   string ID1="someID1";
            string ID2="someID1
";
            
            list = new ArrayList();
            actuaList = new ArrayList();
            table = new Hashtable();
            
            actuaList.Add("A");
            actuaList.Add("CB");
            actuaList.Add("Adv");                    
 
            ServicesWS.RecordSoap service= new ServicesWS.RecordSoap();
            service.Credentials = CPUtil.GetUserCredentials();        

            // Call web service, convert it to list and setting up datasource
           int x = service.GetServices(ID1, ID2).Count<ServicesWS.Service>();

           for (int i = 0; i < x;i++ )
           {
               list.Add(service.GetServices(ID1, ID2).ElementAt<ServicesWS.Services>(i).NAME);
           }

           if (list.Count > 0)
           {
               for (int j = 0; j < list.Count; j++)
               {
                  
                           table.Add(list[j], 1);                      

               }

           }
            
                   for (int i = 0; i < actuaList.Count; i++)
                   {
                      
                          if (!table.ContainsKey(actuaList[i]))
                           {
                              
                               table.Add(actuaList[i], 0);
                              
                           } 
                   }


           keysLst3 = GetKeys(table);       

           // Need these data to display along with other data which are coming from DB.
            keysLst3[0].ToString();
            table[keysLst3[0]].ToString();
        }

Hello naimish,

You need to have at least RadListView's ItemTemplate defined. For tabular data, refer to the RadListView predefined layouts demo to get acquainted with the various predefined listview layouts you can use, or to the RadListView custom layouts demo on how to customize your listview layout.
