AJAX Accordion Control

Download : AJAXAccordionPaneControl.zip

An accordion menu is a collection of multiple, stacked panels. Only one of them is visible and another can be opened by clicking the header of a closed one using a smooth transition of the heights of the content area of the panels. It is like having several CollapsiblePanels where only one can be expanded at a time. The Accordion is implemented as a web control that contains AccordionPane web controls. Each AccordionPane control has a template for its Header and its Content. We keep track of the selected pane so it stays visible across postbacks. 

When I click on Second Menu then second pane will visible while first become hide.
