Infragistics Forums

Hi,
I have made a simple WebAppl with an Ultrawebtab and 3 Pages.
The 3 Pages are called with the Eventhandler:
        void UltraWebTab1_TabClick(object sender, Infragistics.WebUI.UltraWebTab.WebTabEvent e){
            switch (e.Tab.Key){
                case "0": e.Tab.ContentPane.TargetUrl = "Page1.aspx"; break;
                case "1": e.Tab.ContentPane.TargetUrl = "Page2.aspx"; break;
                case "2": e.Tab.ContentPane.TargetUrl = "Page3.aspx"; break;}}
So far it works well.

But when I add a scriptmanager to the 3 pages, I got an error:
 in line 997 of MicrosoftAjaxWebForms.debug.js:
  if (!this._postBackSettings.async) {
Errormessage: 'this._postBackSettings.async' is null or not an object
Any help?

Enviroment: MSVS2008 C# Framework 3.5 and Infragistics35.WebUI.UltraWebTab.v8.1

Okay, here my solution:

    <script type="text/javascript">

    function UltraWebTab1_onInitTab(sender, eventArg2, eventArg3)
    {
        var page = "Page1.aspx";
        var index = 0;
       
        var nam = sender.ID + "_frame" + index;
        document.getElementById(nam).style.cssText = "DISPLAY:block";
        document.getElementById(nam).contentWindow.location.href = page;
        document.getElementById(nam).contentWindow.document.frames[index].location.href = page;
        document.getElementById(nam).contentWindow.location.reload(true);
    }
   
    function UltraWebTab1_onTabClick(sender, item, event)
    {
        var page;
        switch (item.Key)
        {
            case "0":
                page = "Page1.aspx";
                break;
            case "1":
                page = "Page2.aspx";
                break;
            case "2":
                page = "Page3.aspx";
                break;
        }
        var nam = sender.ID + "_frame" + item.Key;
        document.getElementById(nam).style.cssText = "DISPLAY:block";
        document.getElementById(nam).contentWindow.location.href = page;
        document.getElementById(nam).contentWindow.document.frames[item.index].location.href = page;
        document.getElementById(nam).contentWindow.location.reload(true);
    }
   </script>
 
<igtab:UltraWebTab ID="UltraWebTab1" runat="server" AutoPostBack="false">
    <ClientSideEvents Click="UltraWebTab1_onTabClick"
     InitializeTabs="UltraWebTab1_onInitTab" />
    <Tabs>
        <igtab:Tab Key="0" AccessKey="0" Text="Page1" />
        <igtab:Tab Key="1" AccessKey="1" Text="Page2" />
        <igtab:Tab Key="2" AccessKey="2" Text="Page3" />
    </Tabs>
</igtab:UltraWebTab>

Thanks for congratulations!
