Bind dynamic observalecollection to radgridview

[ITA]

Hi,

i have a urgent problem. We have to bind a observalcollection to a RadGridView. The Problem ist that this collection must be dynamic. For Example:
We have a tabel "Customer" with 20 columns and a table "purchasing" with 40 columns and so on... We have to create on runtime all the properties
and the collection!

Is there any standalone wpf example somewhere? All i found are Silverlight-Examples and these will not work with wpf...

Thanks a lot
Best Regards
MJ
