Hierarchical Datagrid Error

[falco]

I am building a hierarchical datagrid that has a relation between 2 tables in a dataset. When I run the app, I get the following error on the aspx page.

Compiler Error Message: CS0117: object does not contain a definition for CreateChildView

Below is the code for the page. Should I be using "Container.DataItem.CreateChildView("relation")" for my datasource in the nested datagrid?

<aspataGrid id=dg runat="server" DataSource="<%# dsProfiles %>" DataMember="tbl_identity" DataKeyField="identity_id" AutoGenerateColumns="False" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" BackColor="White" CellPadding="3" GridLines="Horizontal" CellSpacing="1" Font-Names="Arial" Font-Size="9pt">
