Hello Sindu,

You can add a RadTreeList in NestedViewTemplate of the RadGrid as shown below.
aspx:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="true">
  <MasterTableView>
      <NestedViewTemplate>
          <telerik:RadTreeList ID="RadTreeList1" runat="server" DataSourceID="SqlDataSource2"
              ParentDataKeyNames="ReportsTo" DataKeyNames="EmployeeID" AutoGenerateColumns="false">
                  <Columns>
                 <telerik:TreeListBoundColumn DataField="EmployeeID" UniqueName="EmployeeID" HeaderText="Employee ID" />
                 <telerik:TreeListBoundColumn DataField="LastName" UniqueName="LastName" HeaderText="Last Name" />
                  </Columns>
           </telerik:RadTreeList>
      </NestedViewTemplate>
 </MasterTableView>
</telerik:RadGrid>

Thanks,

hi Shinu;   made me want to do this example, the problem here radtreelist_updatecommand

Hello.  This is a very old post but I am having a problem with RadTreeList inside a NestedViewTemplate of RadGrid.  RadGrid has a DataKeyName=SomeID.  I want to use this SomeID in RadTreeList1_NeedDataSource to filter out the data I want displayed.  How do I access SomeID in that event handler?

If RadGrid has three rows based on SomeID, currently what I am getting is the same RadTreeList repeated three times.  What I need is somehow show RadTreeList based on first SomeID value in first RadGrid-Row and so on...

 

Thank you for your help.

Raka.
