Usage Example

// 1. Assuming observable data set is used for UI binding
IObservableDataSet boundObservableDataSet = new ObservableDataSet();

// The following line is a pseudo-code example of how UI can be bound to the observable data set.
// The actual binding code depends on the UI framework and is not part of POCO DataSet.
somePage.DataContext = boundObservableDataSet;

// 2. User chooses "Reload" to discard local changes and re-sync with server
// Say, you got the response from the server as IDataSet into latestSnapshotFromServer variable:
IDataSet latestSnapshotFromServer = ...

// 3. Call DoReplaceMerge method to refresh the UI with the latest snapshot from the server.
// Itr replaces the entire UI baseline with the server snapshot, discarding all local changes.
IObservableMergeOptions options = new ObservableMergeOptions();
uiDataSet.DoReplaceMerge(fullSnapshotFromServer, options);
