Some Problem with Some ASPX Page

Please could some kind person help me out here. My aspx page comtain following:

In the Content pa开发者_开发百科nel of the one page I have placed 3 AccordionPanes. In this I placed 3 gridview controls. The idea is that when I select one of the rows in the Gridview in Pane 1 or Pane 2 the row should be added to third gridview. ..I hope that makes sense.

When I link the Gridview in a normal page (not using the Accordion control) it works

You will have to use the accordion control's controls collection to access the 3rd grid view, as an accordion is a control container.
