Load On Demand Problems

[34gl3]

Hi,
I am using the LoadOnDemand example, but i have this problem: the tabclick event fires just the first time.
When i click on the second tab it works, but after this when i click on the first tab, the event won't fires.
Here is my code:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function onTabSelecting(sender, args)
        {
             if (args.get_tab().get_pageView())
             {
                   args.get_tab().set_postBack(false);
             }
        }

    </script>
</telerik:RadCodeBlock>

            <telerik:RadTabStrip ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1" SelectedIndex="0" OnClientTabSelecting="onTabSelecting" OnTabClick="RadTabStrip1_TabClick" />
            <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" OnPageViewCreated="RadMultiPage1_PageViewCreated" />

<telerik:RadAjaxLoadingPanel runat="server" ID="LoadingPanel1">
            <asp:Image runat="server" ID="LoadingImage1" ImageUrl="~/Ajax/Img/loading7.gif" AlternateText="Loading..." />
        </telerik:RadAjaxLoadingPanel>
        <telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadTabStrip1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadTabStrip1" />
                        <telerik:AjaxUpdatedControl ControlID="RadMultiPage1" LoadingPanelID="LoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="RadMultiPage1">

                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

Hello LCB,

The behavior you are experiencing is by design. Clicking a tab causes postback only the first time (this is done in the tabSelecting client-side event).
