LinkButton.Command Event
Occurs when the LinkButton control is clicked.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in System.Web.dll)
The Command event is raised when the LinkButton control is clicked. This event is commonly used when a command name, such as Sort, is associated with the LinkButton control. This allows you to create multiple LinkButton controls on a Web page and programmatically determine which LinkButton control is clicked.

The Command event is raised through the control hierarchy in the form of the BubbleEvent. |
