OnClick Method

LinkButton.OnClick Method (EventArgs)

 

Raises the Click event of the LinkButton control.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

Protected Overridable Sub OnClick (
	e As EventArgs
)

Parameters

e
Type: System.EventArgs

A System.EventArgs that contains the event data.

The Click event is raised when the LinkButton control is clicked. This event is commonly used when no command name is associated with the LinkButton control, as in the case of a Submit button.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnClick 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 OnClick in a derived class, be sure to call the base class's OnClick method so that registered delegates receive the event.

The following example demonstrates how to specify and code a handler for the Click event to display which LinkButton control is clicked.
