What is event bubbling

Event Bubbling is nothing but events raised by child controls is handled by the parent control. Example: Suppose consider datagrid as parent control in which there are several child controls.There can be a column of link buttons right.Each link button has click event.Instead of writing event routine for each link button write one routine for parent which will handlde the click event of the child link button events.Parent can know which child actaully
triggered the event.That thru arguments passed to event routine.
