I've been working on a page that utilizes functionality similar to that of the nested repeater example in the CHM file. I believe I've come across a bug in the C# sample included and I thought I'd post it here in case it is a help to anyone else...

The sample code that is supposed to be included in your aspx page includes a line that looks like this:

<asp:repeater id="ChildRepeater" runat="server" datasource='<%# Container.DataItem.Row.GetChildRows("myrelation") %>' >

However, this doesn't work (at least in C# 2.0). You will get an error indicating that object of type "object" doesn't support a property called rows. This is caused by the fact that DataItem is not strongly typed. If you review online samples such as http://support.microsoft.com/default.aspx?scid=kb;EN-US;306154 you will note that you have to cast the DataItem property as a DataRowView as in the following:

<asp:repeater id="ChildRepeater" runat="server" datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("myrelation") %>' >
