LinqDataSourceView::OnSelecting Method (LinqDataSourceSelectEventArgs^)
.NET Framework (current version)
Raises the Selecting event before the LinqDataSource control performs a data-retrieval operation.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
Parameters
- e
-
Type:
System.Web.UI.WebControls::LinqDataSourceSelectEventArgs^
The event data.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Consuming Events.
The OnSelecting method also enables derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors:
When you override the OnSelecting method in a derived class, make sure that you call the OnSelecting method for the base class so that registered delegates receive the event.
