What is an UpdatePanel control?
This is the control that wraps all the controls that need to be partially posted back. A web page may comprise of several UpdatePanels. In case there is any event happening within the controls wrapped inside an UpdatePanel control, the entire page isn't posted back, rather only the contents within the UpdatePanel are posted back to the web server. If the partial postback has to be avoided, set the ChildrenAsTriggers property of the UpdatePanel to false.
Further, the Triggers of an UpdatePanel may be used to set the application in such a way that the partial postback of the UpdatePanel may be invoked from controls that lie outside the UpdatePanel.
