                                        </asp:Panel>
                                        <AjaxControlToolkit:CollapsiblePanelExtender
                                            ID="collapsible_navigation"
                                            runat="server"
                                            CollapseControlID="click_Indexpanel"
                                            TargetControlID="Index_panel"
                                            ExpandControlID="click_Indexpanel"
                                            Collapsed="true"
                                            ExpandDirection="Horizontal">
                                        </AjaxControlToolkit:CollapsiblePanelExtender>

this is teh code of teh second panel
<asp:Panel runat="server" ID="click_Toolboxpanel" Style="height: 130px">

                                            <asp:Image ID="Img_Toolbox" runat="server" Style="cursor: pointer"

                                            <div class="verticalLabel" style="top: -64px; right: 8px; left: -5px; position: relative; text-align: center;">

                                                    Font-Size="8pt" Font-Names="Tahoma" Font-Bold="true"
                                                    ForeColor="White" Style="cursor: pointer"></asp:Label>
                                            </div>
                                        </asp:Panel>
                                        <AjaxControlToolkit:CollapsiblePanelExtender
                                            ID="Cpe_Toolbox"
                                            runat="server"
                                            CollapseControlID="click_Toolboxpanel"
                                            TargetControlID="Toolbox_Panel"
                                            ExpandControlID="click_Toolboxpanel"
                                            Collapsed="true"
                                            ExpandDirection="Horizontal">
                                        </AjaxControlToolkit:CollapsiblePanelExtender>

and these are panels that should shown upon clicking on collapsable:
<asp:Panel ID="Index_panel" runat="server" CssClass="PopupPanelCurveStyle_N" BackColor="White"
                                                Style="min-width: 300px; display: none; padding: 5px; position: relative; z-index: 9999999999999999999">
                                                index
                                            </asp:Panel>

<asp:Panel ID="Toolbox_Panel" runat="server" CssClass="PopupPanelCurveStyle_N" BackColor="White"
                                                Style="display: none; padding: 5px;position: relative; z-index: 9999999999999999999">

thank you but i solved my problem  upon adding in javascript a collapsed event where i collapse all other collapsable panels.
and this solve my problem
below is the code:

function pageLoad() {
            $find("collapsible_navigation").add_collapsed(onIndexcollapsed);
            $find("collapsible_navigation").add_expanded(onIndexexpanded);

            $find("collapsible_Toolbox").add_expanded(onToolboxexpanded);
            $find("collapsible_Toolbox").add_collapsed(onToolboxcollapsed);
        }
 function onToolboxexpanded() {
            $get("<%=ToolboxPanel.ClientID%>").style.display = "block";
            $get("<%=Indexpanel.ClientID%>").style.display = "none";
            var colPanel = $find("collapsible_navigation");
            colPanel.set_Collapsed(true);

            
         }
        function onIndexexpanded() {
            $get("<%=Indexpanel.ClientID%>").style.display = "block";
            $get("<%=ToolboxPanel.ClientID%>").style.display = "none";
            var colPanel = $find("collapsible_Toolbox");
            colPanel.set_Collapsed(true);
            
        }

        function onIndexcollapsed() {
            $get("<%=Indexpanel.ClientID%>").style.display = "none";
           
        }
        
        function onToolboxcollapsed() {
            $get("<%=ToolboxPanel.ClientID%>").style.display = "none";
