I assigned a datasource as a generic Collection as shown in your documentation
http://help.syncfusion.com/UG/User%20Interface/Windows%20Forms/Grid/documents/4342342genericcollection.htm
with the INotifyPropertyChanged-interface for a GGC.
The grid itself is readonly. I use it to select the objects to edit. Edition and update of the object is done by controls in another panel. When updated there, the notifypropertchanged-event raises, and the datasource (collection) contains the updated values.
The grid shows the updated values also. But only when that row is selected! When the updated row is deselected, the old values are shown in the corresponding cells. Reselecting the row, and the new values are shown.
Any idea what could be wrong?
