I have a XamDataPresenter to which the DataContext is assigned a List object and the elements are displayed as rows in the grid by binding the columns to each element's properties.

If a property of one of the elements is changed programmatically, how do I update the XamDataPresenter to reflect this change?  Toggling the view between grid and carousel does it, but I want to do it without having to do this.

Thanks for any assistance.
