Find TabStrip Server Side

[Najid Hanif]

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

C#

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()) {
                   args.get_tab().set_postBack(false);
               }
           }
       </script>
<telerik:RadAjaxLoadingPanel runat="server" ID="LoadingPanel1">
</telerik:RadAjaxLoadingPanel>
   <telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">
       <AjaxSettings>
           <telerik:AjaxSetting AjaxControlID="RadTabStrip1">
               <UpdatedControls>
                   <telerik:AjaxUpdatedControl ControlID="RadTabStrip1" />
                   <telerik:AjaxUpdatedControl ControlID="RadMultiPage2" LoadingPanelID="LoadingPanel1" />
               </UpdatedControls>
           </telerik:AjaxSetting>
           <telerik:AjaxSetting AjaxControlID="RadMultiPage2">
               <UpdatedControls>
                   <telerik:AjaxUpdatedControl ControlID="RadMultiPage2" LoadingPanelID="LoadingPanel1" />
               </UpdatedControls>
           </telerik:AjaxSetting>
       </AjaxSettings>
   </telerik:RadAjaxManager>

   <telerik:RadSkinManager ID="RadSkinManager1" Runat="server" Skin="Office2010Blue"></telerik:RadSkinManager>
   <telerik:RadProgressManager ID="RadProgressManager1" Runat="server"/>

   <div>
     <br/>
     <telerik:RadMultiPage ID="RadMultiPage2" runat="server" SelectedIndex="0" OnPageViewCreated="RadMultiPage1_PageViewCreated"></telerik:RadMultiPage>
   </div>

Any ideas? 

Thanks

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,
