Tab Click event is not getting fired after couple of clicks

[Ritesh]

Hi,

I have kept RadTabStrip inside asp.net user control

<Telerik:RadTabStrip ID="RadTabStrip1" runat="server" AutoPostBack="True" TabDisplayMode="MultiRow" OnLoad="RadTabStrip1_Load" EnableEmbeddedSkins="true"></Telerik:RadTabStrip>

and loading it from an xml file in RadTabStrip1_Load event.

<TabStrip>
<Tab ID="Event Summary" Text="Event Summary" Value="summary.aspx"/>
<Tab ID="About Us" Text="About Us" Value="about.aspx"/>
<Tab ID="Documents" Text="Documents" Value="docs.aspx" IsBreak="True"/>
<Tab ID="Contact Us" Text="Contact Us" Value="contact.aspx"/>
........
</TabStrip>

I am setting RadTabStrip's SelectedIndex property in Page_PreRender method, and On RadTabStrip1_TabClick event I am navigating to different aspx pages.

What I encounter is; after couple of clicks on different tabs, when I click on any tab that renders after IsBreak (ex. Contact Us) and then again click on any tab before IsBreak (ex. Event Summary), tabstrip goes away. It just doesn't render at all.

I also tried to debug. It is hitting Load, PreReder methods but not TabClick in case of failure. Below is the error I get:

Telerik.Web.UI.RadTab.set_Selected(Boolean Value)....

Environment:

Browser: IE11

Telerik UI for ASP.Net Ajax Q1 2016

Visual Studio 2015

Windows Server 2012 R2

Note: I migrated it from Telerik Classic to Telerik UI for ASP.Net Ajax, and it was working fine before.

Please Help.

Hi Ritesh,

Attached you will find a simple implementation, trying to reproduce the issue observed. As it is still incomplete, may I ask you to post here what should be added to this sample, so it reproduces the problem? This way we will be able to troubleshoot it locally and provide you with the most appropriate solution for your case.

That is going to be a bit difficult to replicate the issue in sample project. 

Can we please have a screen sharing session on Friday (4/15) at 8 AM ET so that I can show you the problem.

I can send you the meeting invite. Please send me your email Id.

Hi Ritesh,

As the Telerik public Forum is not a suitable place to discuss support services, such us Remote sessions and exchange credentials for them, I would like to ask you to open a support ticket and continue our communication there. Keep in mind that you will need an active DevCraft Ultimate license in order to be eligible for Remote Web Assistance.

Note that if you can prepare and send us a runnable sample project, this would speed-up considerably the process of identifying the issue.
