DomainDataSource.LoadingData Event

WCF RIA Services

[WCF RIA Services Version 1 Service Pack 2 is compatible with either .NET framework 4 or .NET Framework 4.5, and with either Silverlight 4 or Silverlight 5.]

Occurs when a data loading operation is started.

Namespace:  System.Windows.Controls
Assembly:  System.Windows.Controls.DomainServices (in System.Windows.Controls.DomainServices.dll)

public event EventHandler<LoadingDataEventArgs> LoadingData

This event is raised from Load and enables a handler to cancel the data loading before it starts. When a handler sets Cancel to true, the data loading will be aborted and a subsequent LoadedData event will not be raised. This differs slightly from canceling a data loading by way of CancelLoad.
