Remarks

The SideBarButtonClick event is raised when a button on the sidebar area is clicked.

Note

The SideBarButtonClick event does not raise an event if a Button control with the CommandName property set to Move is outside of the DataList control's sidebar list for the SideBarTemplate object.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnSideBarButtonClick method also allows 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 overriding the OnSideBarButtonClick(WizardNavigationEventArgs) method in a derived class, be sure to call the OnSideBarButtonClick(WizardNavigationEventArgs) method of the base class so that registered delegates receive the event.
