Selected Tab lost when in PageView set not to render

[LeBear]

This is a change in behavior from the previous tab strip, and I believe is a bug.

I have a top-level tab strip (line 1, below) that controls a multi-page (line 15).  The multi-page is set to only render the selected page.  Inside the first page view (line 17), I have another tab strip (line19) and another multi-page (line 28).  Everything is set to selectedindex = 0 so that the first of everything is shown on initial view.

The page loads.  All is well.  I can click on the second level tab (line 19) and see what I need to see.  Say, for example, that I click on tab 4 (in the lower tab strip - line 24).  I see, as expected, the page view 4 (line 38), which is associated with that tab.  And, the 4th tab is selected.

If I click on tab 2 on the top (line 6), then back to tab 1 (line 5), I still see page view 4 (line 38) as expected, but none of the second level tabs (lines 21-25) show as selected.

Only if I set it to render the unselected pages (in the top multi-page, line 15), is the selected tab still selected.

Thank you for checking this out.  As I said, this is a change in behavior.  I would greatly prefer not to have to render everything as I'm trying to save bandwidth on some pretty complex pages.

Thank you.

Hi
I have a "similar" behavior
This is my code on a content page:

<mwc:RadTabStrip ID="rtsPagina" runat="server" EnableEmbeddedSkins="False" SelectedIndex="0"
       Skin="MachinaWeb" MultiPageID="rmpPagina" EnableAjaxSkinRendering="False" EnableTheming="True"
       Font-Bold="True" Font-Size="14px" AutoPostBack="True"  OnClientTabSelecting="onTabSelecting" OnClientTabSelected="onTabSelected"  >
       <Tabs>
           <mwc:RadTab runat="server" LabelResources="Tabella_sima" PageViewID="rpvTabella" />
           <mwc:RadTab runat="server" LabelResources="Scheda_sima" PageViewID="rpvScheda"  />
           <mwc:RadTab runat="server" LabelResources="Giacenze_plma" PageViewID="rpvGiacenze"  />
           <mwc:RadTab runat="server" LabelResources="Documenti_plma" PageViewID="rpvDocumenti"   />
       </Tabs>
   </mwc:RadTabStrip>
    <mwc:RadMultiPage ID="rmpPagina" runat="server" SelectedIndex="0" ScrollBars="None" RenderSelectedPageOnly="true"  >
               <mwc:RadPageView ID="rpvTabella" runat="server"   >
                   <iframe id="ifTabella"  class="container_iframe"  scrolling="no" frameborder="0" marginheight="0px" marginwidth= "0px"   src="Articoli_Tabella.aspx" ></iframe>
                </mwc:RadPageView>
               <mwc:RadPageView ID="rpvScheda" runat="server">
                   <iframe id="ifScheda"  class="container_iframe"  scrolling="no"  frameborder="0" marginheight="0px" marginwidth= "0px"  src="Articoli_Scheda.aspx?IdArticolo=<%= hdfIdSelezionato.Value %>" ></iframe>
                </mwc:RadPageView>
               <mwc:RadPageView ID="rpvGiacenze" runat="server" > </mwc:RadPageView>
               <mwc:RadPageView ID="rpvDocumenti" runat="server" > </mwc:RadPageView>
   </mwc:RadMultiPage>

It works perfectly, but when i click on the second  or third ...   tab it render everything ok but remains the first tab as selected.
How can i resolve this behavior?
Thank you !!!

Hello Francesco,

Could you clarify which versions of the controls you are using since this thread is rather old? I've made a sample page based on the mark-up provided and everything was working as expected on my side.

My suggestion is to use the ContentUrl property of the RadPageView which will render the content of the url in an iframe instead of putting additional one.
