I am using a collapsible panel extender on a shopping page. I am using it to show/hide special offers. The panel containing these is fixed at the bottom of the page. I have the panel working (expanding and contracting), but I need to change the panel to make it collapse downward instead of upward. The default collapse behavior is to collapse upward. This causes a problem for me because there is a gap between the special offers panel and the bottom of the page after collapsing the panel.
My code is below:
<!--teaser panel-->
<asp:UpdatePanel ID="upTeaser" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="lbShowHideTeaserPanel" EventName="Click"/>
</Triggers>
<ContentTemplate>
<asp:AlwaysVisibleControlExtender ID="AlwaysVisibleControlExtender1" runat="server"
TargetControlID="pnlTeaserContainer"
VerticalSide="Bottom"
HorizontalSide="Center"
ScrollEffectDuration=".1"
>
</asp:AlwaysVisibleControlExtender>
<asp:CollapsiblePanelExtender ID="CollapsiblePanelExtender1" runat="server" CollapseControlID="lbShowHideTeaserPanel"
CollapsedText="[+] Show Special Offers" ExpandControlID="lbShowHideTeaserPanel"
ExpandedText="[-] Hide Special Offers" TargetControlID="pnlTeaserContent" TextLabelID="lbShowHideTeaserPanel"
SuppressPostBack="true" >
</asp:CollapsiblePanelExtender>
<asp:Panel ID="pnlTeaserContainer" runat="server" CssClass="teaserContainer">
<asp:Panel ID="pnlTeaserCollapser" runat="server">
<div style="text-align:right;">
<asp:LinkButton ID="lbShowHideTeaserPanel" runat="server"
OnClick="lbShowHideTeaserPanel_Click"
Text="[-] Hide Special Offers" style="color:#ff761b;" ></asp:LinkButton>
</div>
</asp:Panel>
<asp:Panel ID="pnlTeaserContent" runat="server" Visible="true">
<asp:Literal ID="litTeaserText" runat="server"></asp:Literal>
</asp:Panel>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
<!--end teaser panel-->
Basically what I need to do is something to prevent the gap from appearing under the panel after it collapses upward; something akin to "CollapseDirection="up", OR make the panel reposition to the bottom of the screen after collapse if changing the collapse direction is not possible.
Thanks!
