Nested Repeater - 3 levels - datasource

[Ed Allan]

I have extended the example at
http://support.microsoft.com/default.aspx?scid=kb;EN-
US;306154 to build a webform page with 3 layers of nested
Repeaters (ie. parent, child and grandchild).

I added a third DataTable to the DataSet, and created a
second Relation between the second and third DataTables.
On the aspx page I copied the child Repeater to create
the grandchild, referencing the second Relation.

It is throwing an InvalidCastExce ption when executing the
datasource of the innermost Repeater - <%# ((DataRowView)
Container.DataI tem).Row.GetChi ldRows
("childEvents_g randchildEvents ") %> - why does it not
like the cast to DataRowView?

Many thanks in advance.

The offending code is not displayed in the msdn view of
this posting so here it is again <code>((DataRow View)
Container.DataI tem).Row.GetChi ldRows
("childEvents_g randchildEvents ")</code> . . . it is the
cast to DataRowView on the innermost Repeater that
fails . . . what should the datasource for the grandchild
nested repeater be? I've found several posts on various
newsgroups and forums about this problem, but no answers -
surely there's a simple answer?

Did you manage to find a solution to this problem? I'm also having trouble figuring it out...
