<div class="markdown level0 remarks"><p>This event is raised from the <a class="xref" href="C1.Win.Data.Entities.C1DataSource.SaveChanges.html#C1_Win_Data_Entities_C1DataSource_SaveChanges">SaveChanges()</a> method and allows a handler to cancel the operation
before it begins. When a handler sets <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.componentmodel.canceleventargs.cancel">Cancel</a> to
True, the operation will be aborted and a subsequent SavedChanges event
will not be raised.</p>
