    I can't seem to find my Tabstrip from Code behind. here is my setup:

    Codebehind where I try and find tabstrip is loaded from a usercontrol in a multipage

    RadTabStrip tabstrip = (RadTabStrip)Page.Master.FindControl("RadTabStrip1"); //This returns null
    RadTab SelectedTab = tabstrip.Tabs.FindTabByText("Testers"); //and blows up at this line

     Tabstrip , ajax loading panel, and multipage  is setup like this:
    <telerik:RadTabStrip ID="RadTabStrip1" runat="server" SelectedIndex="0" MultiPageID="RadMultiPage2" OnClientTabSelecting="onTabSelecting" OnTabClick="RadTabStrip1_TabClick"></telerik:RadTabStrip>
           <script type="text/javascript">
               function onTabSelecting(sender, args) {
                   if (args.get_tab().get_pageViewID()) {
    <telerik:RadAjaxLoadingPanel runat="server" ID="LoadingPanel1">
       <telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">
               <telerik:AjaxSetting AjaxControlID="RadTabStrip1">
                       <telerik:AjaxUpdatedControl ControlID="RadTabStrip1" />
                       <telerik:AjaxUpdatedControl ControlID="RadMultiPage2" LoadingPanelID="LoadingPanel1" />
               <telerik:AjaxSetting AjaxControlID="RadMultiPage2">
                       <telerik:AjaxUpdatedControl ControlID="RadMultiPage2" LoadingPanelID="LoadingPanel1" />
       <telerik:RadSkinManager ID="RadSkinManager1" Runat="server" Skin="Office2010Blue"></telerik:RadSkinManager>
       <telerik:RadProgressManager ID="RadProgressManager1" Runat="server"/>
         <telerik:RadMultiPage ID="RadMultiPage2" runat="server" SelectedIndex="0" OnPageViewCreated="RadMultiPage1_PageViewCreated"></telerik:RadMultiPage>

    Any ideas?

    Hi Najid,

    You could use the FindControl method  on the ContentPlaceHolder which hosts the user control with the RadTabStrip and the RadMultiPage. Please consider the following implementation:

    protected void Page_Load(object sender, EventArgs e)
             RadTabStrip tabstrip = (RadTabStrip)ContentPlaceHolder1.FindControl("RadTabStrip1");
             RadTab SelectedTab = tabstrip.Tabs.FindTabByText("Testers");

    In the example given the ContentPlaceHolder1 is the PlaceHolder, used to load the UserControl

    Kind regards,
    the Telerik team
