Bubbled Event

Posted By: Ramesh     Posted Date: August 05, 2010    Points:2   Category :ASP.Net
Can anyone tell Bubbled event? Explain in this scenario....

Suppose I have a Button Control inside a GridView. I want to fire the click event for that button. (The Button control is placed inside GridView's ItemTemplate).

If you can supply any sample code, well and good.

The ASP.NET page framework provides a technique called event bubbling that allows a child control to propagate events up its containment hierarchy. Event bubbling enables events to be raised from a more convenient location in the controls hierarchy and allows event handlers to be attached to the original control as well as to the control that exposes the bubbled event.

Event bubbling is used by the data-bound controls (Repeater, DataList, and DataGrid) to expose command events raised by child controls (within item templates) as top-level events. While ASP.NET server controls in the .NET Framework use event bubbling for command events (events whose event data class derives from CommandEventArgs), any event defined on a server control can be bubbled.
