AJAX Collapse All/Expand All

Any thoughts on how to do this? Make all of them on a page collapse or expand. Seems like it shouldn't be terribly hard.

assuming your CollapsiblePanelExtender are inside Form tag having id form1, this should work:
1.Collapse All

Code:

---

        Dim ccpe = From n In form1.Controls Where n.GetType().ToString = "AjaxControlToolkit.CollapsiblePanelExtender" Select n
        'Collapse
        For Each ctl In ccpe
            ctl.Collapsed = True
            ctl.ClientState = True
        Next

---

2.Expand All

Code:

---

        Dim ccpe = From n In form1.Controls Where n.GetType().ToString = "AjaxControlToolkit.CollapsiblePanelExtender" Select n
        'Collapse
        For Each ctl In ccpe
            ctl.Collapsed = False
            ctl.ClientState = False
        Next

---

Thanks!
