I am using an AJAX CollapsiblePanelExtender for several sections of a form. I can collapse a panel programatically using the following 2 lines:
ajaxCollapsiblePanelExtender1.Collapsed = true;
ajaxCollapsiblePanelExtender1.ClientState = "true";
However, the expand/collapse animation does not play as when the Expand/CollapseControlID is clicked. It simply appears in the collapsed state. Is it possible to trigger this animation programatically?
