what am I doing wrong?

[Andrew]

when the page loads I see all the pageviews being displayed for the first tab, it is not till I click through all the tabs once will the pageviews show correctly for the selected tab

Ok here is my code

<telerik:RadTabStrip ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1">
               <Tabs>
                   <telerik:RadTab runat="server" Text="1" PageViewID="rpv1">
                   </telerik:RadTab>
                   <telerik:RadTab runat="server" Text="2" PageViewID="rpv2">
                   </telerik:RadTab>
                   <telerik:RadTab runat="server" Text="3" PageViewID="rpv3">
                   </telerik:RadTab>
               </Tabs>
           </telerik:RadTabStrip>
           <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0">
                   <telerik:RadPageView ID="rpv1" runat="server">
                       <asp:Label ID="Label1" runat="server" CssClass="BoldPrompt" Text="rpv1"></asp:Label>
                   </telerik:RadPageView>
                   <telerik:RadPageView ID="rpv2" runat="server">
                       <asp:Label ID="Label2" runat="server" CssClass="BoldPrompt" Text="rpv2"></asp:Label>
                   </telerik:RadPageView>
                   <telerik:RadPageView ID="rpv3" runat="server">
                       <asp:Label ID="Label3" runat="server" CssClass="BoldPrompt" Text="rpv3"></asp:Label>
                   </telerik:RadPageView>
           </telerik:RadMultiPage>

I'm having the exact same problem.  No help found via searching here or on Google.

<telerik:RadTabStrip ID="radtabDashboard" runat="server" Width="600px" CssClass="Tab_x79" SelectedIndex="0" MultiPageID="radMultiPage1" OnClientTabSelected="radtabSelected">
    <Tabs>
        <telerik:RadTab Text="Quarterly Sales Pipeline" CssClass="Tab_x79" Selected="true" />
        <telerik:RadTab Text="Bi-Annual Incentive" CssClass="Tab_x79" />
    </Tabs>
</telerik:RadTabStrip>
<telerik:RadMultiPage ID="radMultiPage1" runat="server" Width="600px">
    <telerik:RadPageView ID="rpvQuarterly" runat="server" Selected="true">
        <asp:Panel ID="Panel6" runat="server" />
    </telerik:RadPageView>
    <telerik:RadPageView ID="rpvIncentive" runat="server" Selected="false">
        <asp:Panel ID="Panel7" runat="server" />
    </telerik:RadPageView>
</telerik:RadMultiPage>

Tried all kinds of things with SELECTED="False" or Visible="False" (which turns that PageView off and you can't get it back on!)

Even tried this in the codebehind:

Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim sb As StringBuilder = New StringBuilder()
    sb.Append("var radtab = $find('ctl00_ctl00_SiteMasterContentPlaceHolder_NestedSiteMasterContentPlaceHolder_radtabDashboard');" & vbCrLf)
    sb.Append("var multiPage = $find('ctl00_ctl00_SiteMasterContentPlaceHolder_NestedSiteMasterContentPlaceHolder_radMultiPage1');" & vbCrLf)
    sb.Append("if ((multiPage !== null) && (multiPage !== undefined)) {" & vbCrLf)
    sb.Append(" var i;" & vbCrLf)
    sb.Append(" for (i = 0; i < multiPage.get_pageViews().get_count(); i++) {" & vbCrLf)
    sb.Append("  radtab.get_tabs().getTab(i).set_visible(false);" & vbCrLf)
    sb.Append("  multiPage.get_pageViews().getPageView(i).hide();" & vbCrLf)
    sb.Append(" }" & vbCrLf)
    sb.Append("}")
    ScriptManager.RegisterStartupScript(Me.Page, Me.Page.GetType, "radtabInit", sb.ToString, True)
End Sub

Problem still exists.

Hello guys,

Can you please let me know which versions of Telerik.Web.UI you are using?

Regards,
Simon

[Jerry T.]

I'm using 2010 Q3 1317.40

[Andrew]

I am using 2010.3.1215.40

when I was playing around with the controls on my page I noticed that if I moved the RadWindowManager From the top of my page to the bottom of the page the problem with the tabs/ mutlipage went away. But then I lost the styling of my model window also went away.

[Cori]

I've noticed that for Andrew you set the SelectedIndex on the RadMultiPage, while Jerry sets the SelectedIndex on the RadTabStrip. Have you both tried setting the default SelectedIndex on both the RadTabStrip and RadMultiPage to 0, so they are both synced to the same index on initial load?

I hope that helps.

[Jerry T.]

Cori,

Yes, I've tried that and just about every combination of show/hide, visible = false/true, selected=true/false.

That RegisterStartupScript was just one attempt at trying to suppress the 2nd RadPageView at startup.

We got ours working.  The biggest thing was that the StyleSheetReference in our StyleSheetManagerProxy was missing for the MultiPage.  A bit of moving code around and this is what is now working for us:

Hi Jerry T.,

It is good that you have found the cause of the issue. 

Andrew, is your issue the same?

Kind regards,
Simon
the Telerik team

[Andrew]

yes, we did not have a script manager on our page, do you recommend that in projects where masterpage are used that we put a scriptmanager on the masterpage?

[Cori]

A ScriptManager is always required when working with ASP.NET Ajax controls. Best practice is to place it on the MasterPage, so all content pages get the ScriptManager.

[Andrew]

why was able to compile and run my app without a script manager if it is required

[Andrew]

sorry in my prevous posts I was refering a radstylesheetmanager not a scriptmanager but does the same apply for putting it on the masterpage

[Jerry T.]

Yes, it's much better to put a ScriptManager or the StyleSheetManager on the MasterPage and use Proxies on your ASPX pages.

Jerry

I'm having this problem also, but I have the RadScriptManager in my page. If I start clicking back and forth, they will jump into alignment and function as expected. Also, my tabs are just displaying as a bulleted list instead of the outlined tab look. I'm not sure if that's related.

[Chris]

I solved my problem. I used fiddler against my project and another fresh one I built that worked just to see what was different. I determined that the new working project was sending more requests to get the webresources.dll assets and that makes sense why the original wasn't rendering or behaving correctly. I compared code, web.configs, porjects, everything I could think of but couldn't find the difference. Finally I created a new project in my solution, dragged a tab control to it, then started migrating of the pieces from my main project to this new one to see when it would break...but it never did. Using winmerge I still don't see the difference between the working and non-working project directories, but it's working now so I deleted the original and renamed the new one into place. I'm happy it's functioning as expected, but not very happy I could not determine the cause. I'm posting this because someone may benefit from the idea of recreating their project from scratch to solve a strange problem like this.

[Don]

This worked for me :P
