What are the modes of updation in an updatepanel? What are triggers of an updatepanel?..

Answer / Bharti Verma

The modes of updation in an UpdatePanel are 'Always', 'Conditional', and 'PartialRendering'. Triggers in an UpdatePanel are responsible for initiating an asynchronous postback. They have three properties: ControlID, EventName, and TriggerType. The ControlID specifies the ID of the control that causes the update; the EventName specifies the event that triggers the update (usually 'Click'); and the TriggerType defines whether it's a PostBackTrigger or an AsyncPostBackTrigger.
