Bind a GridView DataSource Inside a FormView

I have a FormView that uses an ObjectDataSource to retrieve a business object that contains a collection of children objects. I wanted to display the children in a GridView and it turns out to be very easy to do using Eval:

<asp:GridView ID="GridView1" runat="server" Visible='<%# Eval("HasChildren") %>'
  AutoGenerateColumns="False" DataSource='<%# Eval("ChildrenApplications") %>'>
  <Columns>
      <asp:BoundField DataField="EAAppNum" HeaderText="EA ID" SortExpression="EaIdNegative" />
      <asp:HyperLinkField DataNavigateUrlFormatString="ApplicationForm.aspx?pid={0}" DataNavigateUrlFields="ID"
          DataTextField="Name" HeaderText="Name" SortExpression="Name" />
  </Columns>
</asp:GridView>
