Do you have any documentation on initializing and expression editor in code-behind and binding its Item proprty to either an ObservableCollection<T> or a datatable?

I am going to use it to filter a radgridview but the gridview is generated dynamically at runtime so I can't use XAML to bind the grid data to the expression editor.

Giving the user the option to use RadDataFilter or RadExpressionEditor to filter the same RadGridView so if you have anything on that particular scenario it would be appreciated.

I assume I will have to maybe accomplish it with one or the other unbound. Such as binding the grids itemsource to the datafilters filteredsource and changing the datafilters source after the expressioneditors changed event is fired... etc... please advise if there is a better way.

Figured it out .

RadExpressionEditor.Item = new BusinessObject matching grid itemsource business object class.
