create radgrid inside other rad grid (hierarchy)

[hugo]

Hi all.

I have a question, Im currently working with radGrid and I need create hierarchy with this controls, but I need get data source from code-behind. In my first radgrid I can get data from code-behind but  I can't see the another radgrid in code.
I declared my two controls by this way:

<telerik:RadGrid ID="grdCompCliente" runat="server" Width="100%" Height="100px" OnItemDataBound="grdCompCliente_ItemDataBound1"
                   AutoGenerateColumns ="false" ShowGroupPanel="true">
                       <MasterTableView AllowMultiColumnSorting="True" >

                       <NestedViewTemplate>
                       <asp:Panel runat="server" ID="InnerContainer" Visible="false">
                           <telerik:RadGrid  runat="server" ID="ID_Subasta" >
                               <MasterTableView>
                                  <Columns>
                                  <telerik:GridBoundColumn DataField="Id" HeaderText="ID">

                                  </telerik:GridBoundColumn>
                                  </Columns>
                               </MasterTableView>
                           </telerik:RadGrid>
                       </asp:Panel>
                       </NestedViewTemplate>

                       </MasterTableView>
                   </telerik:RadGrid>

How can I do these?

Thank you for your attention!!

Hello,

<telerik:RadGrid ID="grdCompCliente" runat="server" Width="100%" Height="100px" AutoGenerateColumns="false"
          ShowGroupPanel="true" OnNeedDataSource="grdCompCliente_NeedDataSource" OnItemDataBound="grdCompCliente_ItemDataBound">

                  <asp:Panel runat="server" ID="InnerContainer">
                      <telerik:RadGrid runat="server" ID="RadGrid1" OnNeedDataSource="RadGrid1_NeedDataSource">
                          <MasterTableView>
                              <Columns>
                                  <telerik:GridBoundColumn DataField="ID" HeaderText="ID">
                                  </telerik:GridBoundColumn>

              </Columns>
          </MasterTableView>
      </telerik:RadGrid>

protected void grdCompCliente_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridNestedViewItem)
        {

            ((RadGrid)e.Item.FindControl("RadGrid1")).Rebind();
            // Another way to acieve this thing but you have to hadle pagging/sorting...etc your own way
            // if you want to assign datasource here then remove "RadGrid1_NeedDataSource" event
            //((RadGrid)e.Item.FindControl("RadGrid1")).DataSource = "";

        }
    }

    protected void grdCompCliente_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        dynamic data = new[] {
                new { ID = 1, Name ="Name1"},
                new { ID = 2, Name = "Name2"},
                new { ID = 3, Name = "Name3"},
                new { ID = 4, Name = "Name4"},
                new { ID = 5, Name = "Name5"}
            };
        grdCompCliente.DataSource = data;
    }
    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        RadGrid RadGrid1 = sender as RadGrid;
        string ID = ((RadGrid1.NamingContainer as GridNestedViewItem).ParentItem as GridDataItem).GetDataKeyValue("ID").ToString();

        dynamic data = new[] {
                new { ID = 1, Name ="Name1" + ID},
                new { ID = 2, Name = "Name2"+ ID},
                new { ID = 3, Name = "Name3"+ ID},
                new { ID = 4, Name = "Name4"+ ID},
                new { ID = 5, Name = "Name5"+ ID}
            };
        RadGrid1.DataSource = data;
    }

let me know if any concern.
