What is Bubbled Events in Asp.net

     Ans) For all these controls when postback controls are used as part of them like button in Gridview. We have to handle them with a concept called “Bubbled Events”

               Gridview captures the event, Gridview call it’s own event called “Row Command”

                 Repeater/DataList ----- “Item Command”

                   When a container control like Gridview , DataList, Repeater are also contains postback controls and when they cause a postback . The event raised by the container control in response to it called  “Bubbled Event”

Two attributes are  called ------ CommandName and CommandArgument are used to interact with Bubbled events. These attributes are for “ ChildPostBack Controls”

CommandName  :   Specifies name for postback control.
