Closed Issue: CollapsiblePanelExtender conflicts with SliderExtender [11805]

Using CollapsiblePanelExtender and SliderExtender at the same time causes the handler of SliderExtender to dissapear, if Collapsed="true".

<cc1:CollapsiblePanelExtender ID="cpe" runat="server" AutoCollapse="False" AutoExpand="False"
CollapseControlID="lblAdjust" Collapsed="true" CollapsedSize="0" ExpandControlID="lblAdjust"
ExpandDirection="Vertical" ExpandedSize="100" ScrollContents="false" SuppressPostBack="True"
TargetControlID="pnlResults">
</cc1:CollapsiblePanelExtender>

<div class="pnlAdjustLink">
<asp:Label runat="server" ID="lblAdjust" Text="[<u>Adjust</u>]" />
</div>

<asp:Panel ID="pnlResults" runat="server">
<asp:TextBox ID="slName" runat="server" Text="50" />
<asp:TextBox ID="tbName" runat="server" CssClass="tbSliderValue" />

<cc1:SliderExtender ID="SliderExtender2" runat="server" TargetControlID="slName"
BoundControlID="tbName" Orientation="Horizontal" Minimum="0" Maximum="100" Length="160" />
</asp:Panel>
