System.Web.UI.WebControls.Repeater and multiple templates

[Robert]

Hi,
if I create a class A with some properies, then create classes B and C
derived from A, later create and ArrayList filled with some B and C items.
This list I would like to use as a datasource for a repeater control. Is it
possible to add more than one <ItemTemplate>? I would like to have i.e two
templates, one for B and second for C object.
I'm using ASP.NET (2.0) very shortly, but I haven't discovered much about
Repeater/Datalist/Datagrid.
Thank you very much.
Robert

Every Templated databound controls (e.g. datagrid, datalist, repeater) takes
one datasource only. To attach several itemtemplates with several
datasources, you will need to nest databound controls and customize the
codebehind to databind each template (which contain a different user control)
to a different datasource.

I have an example of a datagrid that uses another user control (which is a
child datagrid) within the ItemTemplate to display hierarchical information
(Company table related to the employees table)
1) This sample http://www.societopia.net/Samples/DataGrid_Hierarchy.aspx is
done in declarative mode to make it easy to preserve the event handling.
2) This one http://www.societopia.net/samples/webform2.aspx is done by
dynamically building the datagrid because I do not assume that the levels of
hierarchy are known at design time
