Hi,

I'm trying to follow the code provided here http://www.infragistics.com/help/winforms/piechart-data-binding

I've added a class named PieData and added the vb code from the DataItem in the sample.

First issue I run into, was that I needed to Import the System.Collections.ObjectModel in order for the project to compile.

Now the project compiles, but when I try to actually Bind the Data to the UltraPieChart control, I'm getting the error:

"DataSource must implement an IBindingList, IListSource, IList, or an IEnumerable"

What am I missing here ?
