FIX. RadGridView - the RowsChanged event arguments are incorrect.
Update the data source directly and check the OldItems array.

RadGridView is bound to a collection of objects that implement the INotifyPropertyChanged interface. The user changes the value of a property of an object grammatically. INotifyPropertyChanged gives us the ability to understand when the value is changed and update this value in the grid, but we do not have information about the previous state of the object.
