TargetControlID of AJAX Calendar Control cannot be found when in an AJAX tab control


I have a caledar control tied to a text box within a tab panel control as below.


   <cc1:TabContainer ID="TabContainer1" runat="server" Width="100%">
   <cc1:TabPanel ID="TabPanel4" runat="server" HeaderText="Class Details">

<ContentTemplate >
    <table style="width: 747px">
            <td style="width: 136px">
            <td style="width: 100px; text-align: right;">
                <asp:HyperLink ID="hlSurveyResponse" runat="server" Width="203px">Survey Response</asp:HyperLink></td>
            <td style="width: 136px">
            <td style="width: 100px">
                <asp:DropDownList ID="ddlClass" runat="server" AutoPostBack="True">
            <td style="width: 136px">
                SRV Code</td>
            <td style="width: 100px">
                <asp:Label ID="lblSRVCode" runat="server" Width="208px"></asp:Label></td>
            <td style="width: 136px">
            <td style="width: 300px">
                <asp:TextBox ID="txtDuration" runat="server" MaxLength="2" Width="15px" ></asp:TextBox>
            <td style="width: 136px">
                Start Date</td>
            <td style="width: 100px">
                <asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox>
                <cc1:CalendarExtender  OnClientDateSelectionChanged="hideCalendar" ID="calStartDate" runat="server"  Format="dd MMM yyyy" TargetControlID="txtStartDate">

  On selecting the calendar date I receive following javascript error:

aspnetForm.ctl00.ContentPlaceholder1.txtStartDate.value is null or not an object.

 If I take the txtStartDate control out of the tab panel, everything is golden.

Any suggestions?

My bad.

I had a Javascript written on the page which looked at the control and set value of another control.

Had to modify the javascript to change the control name.

Now all set.

I do not see Tab control in my AJAX Control Toolkit.
First, how do I update my version of the AJAX Control Toolkit to the latest? Second, is there a way to tell what version of AJAX Control Toolkit I have? Third, I do not see the Tab control as one of the available AJAX controls in my Toolbox. Am I missing something? If you just have a reference to the AjaxControlToolkit.dll - you just need to delete it and reference the latest version. If you have a project reference, you'll need to make sure the project is the version you want and rebuild it. You'll also be able to see if the folder for Tabs is there - it should be as I believe it was in ...

I was going to post this in the general ASP.NET FAQ, but it didn't really fit, and there was no AJAX FAQ, so I'm posting it here.
