I'm trying to connect my datasource (from sproc) to a radtreelist control.

I have added multiple levels with null values in the hierarchy to try to match the requirements for null values to set the nested levels but I am still getting "No records".

Here's a sample of my data:

wbs1        wbs2    wbs3    Name                                                                          PreConDate  DaysSincePrecon
2009.0257                  
2009.0257   ESTR.1             
2009.0257   ESTR.1  U0001   31 Drakestown Road - Main Project   08/04/2010  1147
2009.0257   LEED.1             
2009.0257   LEED.1  U0001   31 Drakestown Road - Main Project   08/04/2010  1147
2010.0662                  
2010.0662   GRES.1             
2010.0662   GRES.1  U0001   102 Creekview Drive 05/24/2013  123
2010.0662   GRES.1  U0002   170E Monmouth Street    05/24/2013  123

What I'm trying to do, is display a page of project numbers (wbs1) all condensed. When I click on the "expand" icon, I'd like it to show all levels that have only the second level (wbs2) and no third level (wbs3). And when I click "expand" on the wbs2, I'd like it to display all of the rows that share the wbs2.  I can change the sproc so that it gives me any configuration, i.e. nulls at some level, 0 at some level, etc.

Here's my aspx code:
<telerik:RadTreeList ID="RadTreeList1" runat="server" DataKeyNames="wbs3" ParentDataKeyNames="wbs1"
        Width="800px" Skin="Windows7" GridLines="Both" AutoGenerateColumns="true" DataSourceId="SqlDataSource1" >
 </telerik:RadTreeList>

 
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:SqlConnectionString %>"
        SelectCommand="dbo.getDataSproc" SelectCommandType="StoredProcedure">
</asp:SqlDataSource>

Thanks in advance.

Hi,

 The data in the table should have a foreign key relationship that will actually specify the hierarchical structure. It can be a self referencing relationship like the Employees table from Northwind. Then you set the primary key as DataKeyName and the foreign key field as ParentDataKeyName - this way the control will now exactly how to build the hierarchy.
Here is a sample data:

ID     ParentID     wbs1            wbs2     wbs3    Name                                                               PreConDate     DaysSincePrecon
 1            0            2009.0257                 
 2            1            2009.0257    ESTR.1            
 3            2            2009.0257    ESTR.1  U0001   31 Drakestown Road - Main Project       08/04/2010        1147
 4            1            2009.0257    LEED.1            
 5            4            2009.0257    LEED.1  U0001   31 Drakestown Road - Main Project       08/04/2010        1147
 6            0            2010.0662                 
 7            6            2010.0662    GRES.1            
 8            7            2010.0662    GRES.1  U0001   102 Creekview Drive                                  05/24/2013        123
 9            7            2010.0662    GRES.1  U0002   170E Monmouth Street                             05/24/2013        123
