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.
Gets an object that represents the method represented by the specified delegate.
