Hi there -

I'm using Visual Studio SP1 2005 with IE 6.  I installed AJAX Release 10301 since I was having some error messages in the eventlog that was related to the CollapsiblePanel.  From what I read, it appeared that I may be experiencing the memory leak that had been identified.  So with the new  AJAX installed I migrated the application and am now having trouble with the collapsiblepanel in that it is not "visible".  I have a page that has about 4 panels that default to collapsed.  When one is opened, modifying the data (e.g. a grid) goes to another page and comes back to this original page.  In the load of the page, I determine if any of the panels need to be open.  With Atlas, I programmatically set collapsed to false and it worked great. 

 cpePhone.TargetProperties[0].Collapsed = false;

 With AJAX

  cpePhone.Collapsed = false;

does not work.  I also added cpePhone.ClientState="false" but it is not visible.  I know it's there since when I close the panel it displays and then collapses.

Below is the code:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="actk" %>
   <asp:ScriptManager id="ScriptManager" EnablePartialRendering="true" runat="Server"  ></asp:ScriptManager>


 <asp:Panel runat="server" ID="pPhoneCollapsed" Font-Names="Verdana" Font-Size="10pt" style="margin-left:14pt"> 
    <div style="font-family:Verdana; font-size:10pt;" >
        <asp:Image runat="server" ID="imgPhone" ImageUrl="~/App_Themes/Basic/plus.bmp" />
        <asp:Label ID="lblPhone" runat="server" SkinID="lblForm" Text="Phone Number(s)" ></asp:Label>
        &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
        <asp:ImageButton ID="btnAddPhone" runat="server" CommandName="gvAddPhone" ToolTip="Add Phone" 
            ImageUrl="~/App_Themes/Basic/add.gif" OnClick="btnAddPhone_Click" CausesValidation="true"  />
   </div>
 </asp:Panel>  

 <asp:Panel runat="server" ID="pPhoneShow" Height="0" style="margin-left:14pt" >
   <asp:GridView ID="gvPhone"  runat="server"  SkinID="gvGrayHeader"
      DataKeyNames="phone_id"
      OnRowCreated="gvPhone_RowCreated"
      OnRowCommand ="gvPhone_RowCommand"
      AutoGenerateColumns="false" >
        <Columns>
            <asp:HyperLinkField DataNavigateUrlFields="phone_id,phone_scope,org_id,contact_id,phone_type" DataNavigateUrlFormatString="~/Phone.aspx?PID={0}&PS={1}&OID={2}&CID={3}&PT={4}"
                DataTextField="description" NavigateUrl="~/Phone.aspx"  HeaderStyle-HorizontalAlign="Left" HeaderText="Type" ControlStyle-Width="100" >
            </asp:HyperLinkField>
            <asp:TemplateField HeaderText="Number" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" >
                <ItemTemplate> 
                    <%# Eval("phone_number") %> 
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField>
                <ItemTemplate>
                    &nbsp;&nbsp;
                    <asp:ImageButton ID="btnDelete" runat="Server" CommandName="gvDelete"  CausesValidation="false"
                         ImageUrl="~/App_Themes/Basic/Delete_can.gif" ToolTip="Delete" 
                         OnClientClick="return confirm('Do you want to Delete?');" />
                    &nbsp;      
                </ItemTemplate>
            </asp:TemplateField>
         </Columns>
    </asp:GridView>
  </asp:Panel> 
  

 <actk:CollapsiblePanelExtender ID="cpePhone" runat="server" 
     TargetControlID="pPhoneShow" CollapseControlID="pPhoneCollapsed" 
     ExpandControlID="pPhoneCollapsed" Collapsed="true" TextLabelID="lblPhoneCollapsed" 
     ExpandedText="Phone Number(s)" CollapsedText="Phone Number(s)" 
     ImageControlID="imgPhone" ExpandedImage="App_Themes/Basic/minus.bmp" CollapsedImage="App_Themes/Basic/plus.bmp"
     SuppressPostBack="false" />
 

The .cs file the Load calls the method to keep the panel open:

cpePhone.Collapsed = false;

cpePhone.ClientState = "false";  

Any ideas for how to get the panel to display instead of looking like it's open but it's not visible?

Thanks for your help.

Ok, sorry for the post in the first place.  I finally figured it out.  As I have read on this subject, one of the suggestions is to add style="overflow:hidden".  After adding it to the panel tag, it did the trick.  I didn't need the ClientState property just adding that portion to the panel tag.

Thanks for those of you that were viewing the post and possibly offering ideas.
