Represents the asynchronous callback method that a data-bound control supplies to a data source view for asynchronous insert, update, or delete data operations.
Assembly: System.Web (in System.Web.dll)
Public Delegate Function DataSourceViewOperationCallback ( _ affectedRecords As Integer, _ ex As Exception _ ) As Boolean
Dim instance As New DataSourceViewOperationCallback(AddressOf HandlerMethod)
public delegate bool DataSourceViewOperationCallback( int affectedRecords, Exception ex )
public delegate bool DataSourceViewOperationCallback( int affectedRecords, Exception^ ex )
JScript does not support delegates.
Parameters
- affectedRecords
- Type: System.Int32
The number of records that the data operation affected.
- ex
- Type: System.Exception
An Exception, if one is thrown by the data operation during processing.
Return Value
Type: System.BooleanA value indicating whether any exceptions thrown during the data operation were handled.
By default, ASP.NET Web page and control execution is synchronous. However, data source controls can be extended to support asynchronous data retrieval and data operations. The DataSourceView object supports the Insert, Update, and Delete methods for asynchronous data processing. The DataSourceViewOperationCallback delegate is passed to the data source view by a data-bound control, so that the view can call this delegate when asynchronous processing is complete and notify the data-bound control of the operation's outcome.
