ChangingEventArgs is the data class for the following events:

• BaseEdit.EditValueChanging
• RepositoryItem.EditValueChanging

Remarks

The RepositoryItem.EditValueChanging event is raised when the edit value is about to be changed. It enables you to prevent the value from changing. Thus, the CancelEventArgs class introduces the ChangingEventArgs.NewValue and ChangingEventArgs.OldValue properties that identify the potential and current edit values. The inherited Cancel property can be used to cancel the action.

ChangingEventArgs objects are automatically created, modified and passed to RepositoryItem.EditValueChanging event handlers.
