XamGrid has a property ItemSource which can be used for data binding.
If I want to a editable xamGrid, what kind of data collection can be used as datesource of xamGrid?
Wcf ria service returns the default IEnumerable<T> as data collection. Can it be used for editable xamGird?
Editable? As in changing existing rows? That would be dictated by the data object, and if there are setters on the property.
Add/Delete Row able. Well IEnumberable does not have .Remove/.Add methods, so if you want to add / remove rows you would need to be an IList<> or IEditableCollectionView with .CanAddNew / .CanRemove set properly.
