Using the output of repeater as a datasource for a nested GridView

[Kieran]

Hello,
I am trying to use a GridView nested within a repeater to group items
together.

To do this I would like to use the output of the repeater control
(int_pk_parent_definition_id) to be the SQL parameter for the stored
procedure which is the datasource for the GridView.

Any ideas? Help would be much appreciated. I've included what I've
done so far below but it doesn't work because
"int_fk_definition_parent_id" isn't a property of Repeater2...

Thanks in advance,
Kieran

<asp:Repeater ID="Repeater2" runat="server"
DataSourceID="ParentDefinitions" >
<ItemTemplate>
<%# Eval("str_definition_name") %>
<br />
<asp:HiddenField
ID="hfldParentDefID" runat="server" Value="1"/>

<asp:GridView ID="GridView1"
runat="server" AllowPaging="False" AllowSorting="True"
AutoGenerateColumns="False" DataKeyNames="int_pk_defintion_id"
DataSourceID="ChildDefinitions">

<asp:BoundField DataField="dt_created"
HeaderStyle-HorizontalAlign=Left HeaderText="Datecreated"
SortExpression="dt_created" />

</asp:GridView>

</ItemTemplate>
</asp:Repeater>

<asp:SqlDataSource
ID="ParentDefinitions" runat="server" ConnectionString="<%$
ConnectionStrings:CRN_CRMConnectionString %>"

SelectCommand="p_defParentDefinitionListAll"
SelectCommandType="StoredProcedure"></asp:SqlDataSource>

<asp:SqlDataSource ID="ChildDefinitions"
runat="server" ConnectionString="<%$
ConnectionStrings:CRN_CRMConnectionString %>"

SelectCommand="p_p_defChildDefinitionListForParent "
SelectCommandType="StoredProcedure">
<asp:ControlParameter
ControlID="Repeater2" Name="int_fk_definition_parent_id"

PropertyName="int_pk_definition_parent_id" Type="Int32" />
</asp:SqlDataSource>
