public class SharePointClientDownloadCompletedEventArgs : System.ComponentModel.AsyncCompletedEventArgs

'Declaration
 
Public Class SharePointClientDownloadCompletedEventArgs 
   Inherits System.ComponentModel.AsyncCompletedEventArgs

'Usage
 
Dim instance As SharePointClientDownloadCompletedEventArgs

public sealed class SharePointClientDownloadCompletedEventArgs : System.ComponentModel.AsyncCompletedEventArgs

function Leadtools.SharePoint.Client.SharePointClientDownloadCompletedEventArgs()

public ref class SharePointClientDownloadCompletedEventArgs : public System.ComponentModel.AsyncCompletedEventArgs

The SharePointClient class supports downloading an item asynchronously through the DownloadFileAsync and GetDownloadStreamAsync methods. When you call these methods, control returns instantly to your program and the Leadtools.SharePoint.Client.SharePointClient.DownloadCompleted event will occur when the download operation is completed. The event occurs whether or not the operation is successful.

Note: The SharePointClientDownloadCompletedEventArgs class derives from the standard .NET System.ComponentModel.AsyncCompletedEventArgs class and adds those properties needed to support downloading from a SharePoint server.

After the download finishes, the Leadtools.SharePoint.Client.SharePointClient.DownloadCompleted event is fired with a SharePointClientDownloadCompletedEventArgs object containing the following information about the operation:

Property	Value
SourceUri	The source URI. This is the same value as the sourceUri parameter passed to the DownloadFileAsync or GetDownloadStreamAsync method.
DestinationFileName	The destination file name. This is the same value as the destinationFileName parameter passed to the DownloadFileAsync method if that method was called to initiate the download. If the GetDownloadStreamAsync method was called to initiate the download, then the value of this property is null (Nothing in Visual Basic).
DestinationData	A SharePointClientDownloadData object that contains the download stream information if GetDownloadStreamAsync was called to initiate the download. If DownloadFileAsync was used to initiate the download, then the value of this property will be null (Nothing in Visual Basic) Note that you are responsible for calling the System.IDisposable.Dispose method on the DestinationData property if you subscribe to the Leadtools.SharePoint.Client.SharePointClient.DownloadCompleted event.
System.ComponentModel.AsyncCompletedEventArgs.Error	Gets a value that indicates which error occurred during the asynchronous download operation. If an exception is raised during the asynchronous download operation, the class will assign the exception to the System.ComponentModel.AsyncCompletedEventArgs.Error property. The client application's event-handler delegate should check the System.ComponentModel.AsyncCompletedEventArgs.Error property before accessing any properties in SharePointClientDownloadCompletedEventArgs. The value of the System.ComponentModel.AsyncCompletedEventArgs.Error property is null (Nothing in Visual Basic) if the operation was canceled
System.ComponentModel.AsyncCompletedEventArgs.UserState	Gets the unique identifier for the asynchronous download operation. The value of this property is the same as the userState parameter passed to the DownloadFileAsync or GetDownloadStreamAsync method.
System.ComponentModel.AsyncCompletedEventArgs.Cancelled	true if the asynchronous download operation has been canceled; otherwise, false. This class does not change the value of this property from its default value of false.

For an example, refer to DownloadFileAsync or GetDownloadStreamAsync.
