Hi I've attached a sample project that demonstrates binding to the UltraWebGrid doesn't follow the itypedlist logic explained here:http://msdn.microsoft.com/en-us/library/ms404298.aspx

When the UltraWebGrid calls GetItemProperties the listAccessors() count reflects the number of objects not the hierarchy of the object's collections as expected. UltraWinGrid does follow the articles logic and when calling GetItemProperties, listAccessors() reflects the hierarchy .

Is there a reason for the difference?

Cheers
