Hello,

I've the following problem using WebTab 14.2 with "EnabledAjax" option set to TRUE, into Web forms 4.0, rendering with IE9.

I zipped a basic test form where you can reproduce the problem.

Structure :

- WebTab

-----Tab1

----------ButtonInside

-----Tab2

-ButtonOuside

When I programmatically add a new tab from the ButtonOustside click --> the new tab is added.

When I programmatically add a new tab from the ButtonInside click --> visually nothing happen, although the code is parsed.

Do I need to put some kind of trigger to refresh the tab header bar ? A solution without full postback would be nice !

Here is the code for the structure (included in .zip):

    <form id="form1" runat="server">
    <ig:WebScriptManager ID="WebScriptManager1" runat="server">
    </ig:WebScriptManager>
    <div>
        <ig:WebTab ID="WebTab1" runat="server" Height="200px" Width="200%">
            <Tabs>
                <ig:ContentTabItem runat="server" Text="Tab 1">
                    <Template>
                        <asp:Button ID="Button2" runat="server" Text="From inside" OnClick="Button2_Click" />
                    </Template>
                </ig:ContentTabItem>
                <ig:ContentTabItem runat="server" Text="Tab 2">
                </ig:ContentTabItem>
            </Tabs>
            <PostBackOptions EnableAjax="True" />
        </ig:WebTab>
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="From outside" />
    </div>
    </form>

Thank you !
