how to add info to grid hierarchy

[hugo]

Hi all!!

I'm working with a RadGrid with hierarchies, but I have a couple of problems, I've managed to show the internal grids but when I display information in an internal grid I can not do depending on the value that has the grid father, my question is:
How I can make the relationship between parent and child grid?, And how to make each internal grid have different information?

Here is my code:

<telerik:RadGrid ID="grdCompCliente" runat="server" OnItemCommand="grdCompCliente_ItemCommand1"
                        OnItemCreated="grdCompCliente_ItemCreated1"
                        OnItemDataBound="grdCompCliente_ItemDataBound1" Skin="Windows7">
                        <HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">
                        </HeaderContextMenu>
                        <MasterTableView AllowMultiColumnSorting="True" EnableNoRecordsTemplate="true"
                            GroupLoadMode="Server" ShowHeadersWhenNoRecords="false">
                            <NestedViewTemplate>
                                <asp:Panel ID="InnerContainer" runat="server" Visible="false">
                                    <telerik:RadGrid ID="grdPostores" runat="server" >
                                        <MasterTableView AutoGenerateColumns = "true">
                                            <Columns>
                                                <telerik:GridBoundColumn DataField="Nombre" HeaderText="Nombre del Postor">
                                                </telerik:GridBoundColumn>
                                            </Columns>
                                        </MasterTableView>
                                    </telerik:RadGrid>
                                    <telerik:RadButton ID="cmdAgregarPostor" runat="server"
                                        CausesValidation="False" Text="Agregar Postores">
                                    </telerik:RadButton>
                                </asp:Panel>
                            </NestedViewTemplate>
                            <CommandItemSettings ExportToPdfText="Export to PDF" />
