I am using a updatepanel control, which contains a CollapsiblePanelExtender to expand/collapse a panel.
When the page loads for the 1st time i need the panel to be collapsed (which i am able to do). What i need is - When expand link is clicked, the panel should get expanded and should show some data in a grid. How to do this. Sample code would help.
Point is that when the page loads for the first time with collapsed panel, no call to populate data grid should be happening. Only when panel is expanded the call to populate grid needs to happen.
