I use actually Ajax.Updater from Prototype.js to change Div which contain an ultraChart that work but the Problem ist the Tooltips, if the ultraChart is changing, the Tooltips didnt Work, i am getting  "undefined" or some Tooltips from preceed ultraChart.

                    <div class="csc-textpic csc-textpic-intext-right-nowrap">
                        <a href="#" onclick="BLOCKED SCRIPTProductToCompany()" title=" PDF exportieren" class="pdfExport">&nbsp;</a>
<%= Html.DropDownList("DistributionProductToCompany", (IEnumerable<SelectListItem>)ViewData["KeywordGroups"], new { onchange = "DistributionProductToCompanyChange();" })%>
                    </div>
                    <div id="DistributionProductToCompanyContent">
                        <igchart:UltraChart ID="UCDistributionProductToCompany" runat="server">
                            <ClientSideEvents ClientOnMouseClick="BarStacked_ClientOnMouseClick" />
                        </igchart:UltraChart>
                        <cc1:IGMvcScriptManager ID="IGMvcScriptManager5" runat="server" />
                    </div>

on Dropdown onchange i call a javascript Function with Ajax.Updater and change the div: DistributionProductToCompanyContent with another ultrachart (and for this new chart, the tooltips doesnt work)
