We noticed that we can get into the TabStrip (with Keyboard navigation enabled) with the tab key, unfortunately, we can't get out afterwards with back tab (SHIFT + TAB).

Release R3 2021 SP1

The issue is replicated in R3 2021 only. 

<telerik:RadTabStrip runat="server"  ID="RadTabStrip1" >
    <Tabs>
        <telerik:RadTab Text="Tab 1">
            <Tabs>
                <telerik:RadTab Text="fail"></telerik:RadTab>

        <telerik:RadTab Text="Tab 3"></telerik:RadTab>
    </Tabs>
</telerik:RadTabStrip>

Solution from Admin:

Place the load/script below somewhere under the ScriptManager. It can be added in the MasterPage if needed:

<script>
    Sys.Application.add_init(function fixTabStrip() {
        if (Telerik && Telerik.Web && Telerik.Web.UI && Telerik.Web.UI.RadTabStrip) {
            Telerik.Web.UI.RadTabStrip.prototype._childInserted = function (index, tab, owner) {
                this._allTabs = null;

                if (this._cachedSelectedTab) {
                    owner._setSelectedIndex(this._cachedSelectedTab.get_index());
                    this._cachedSelectedTab = null;
                }

                if (tab._cachedSelected) {
                    owner._setSelectedIndex(index);
                    tab._cachedSelected = false;
                }

                Telerik.Web.UI.RadTabStrip.callBaseMethod(this, "_childInserted", [index, tab, owner]);

                if (tab.get_isBreak()) {
                    var breakElement = document.createElement("li");
                    breakElement.className = "rtsBreak";
                    owner.get_childListElement().insertBefore(breakElement, tab._element.nextSibling);
                }

                //if (tab.get_parent() && tab.get_parent() instanceof Telerik.Web.UI.RadTab && tab.get_parent().get_selected()) {
                //    $telerik.$(tab.get_parent().get_levelElement()).removeClass("rtsHidden");
                //}
            }

When adding a child tab programmatically to a second TabStrip tab that has no child item, the newly created child tab will not show up.

Workaround is to remove the class that was hiding the child element:

if (selectedTab.get_tabs().get_count() > 0) {
    $(selectedTab.get_levelElement()).removeClass("rtsHidden");
}

The disabled tabs don't look like disabled in Classic render mode. 

This issue is not observable with the 2016 release as shown in the attached screenshot.

Workarounds:
1) You can change the color of the disabled items by applying the following class to the page:

        .rtsLink.rtsDisabled {
            color: #a5a5a5 !important;
        }

2) Another option is to switch the rendering to Lightweight -> RenderMode="Lightweight".

While it is currently possible to target the first or last item in a RadTabStrip via their CSS classes .rtsFirst and .rtsLast, it is not possible to target individual items, e.g. to add a custom icon or display different background images in tabs.

Assigning icons via the ImageURL property is often not feasible, e.g. when using the RadTabStrip-based navigation controls in Sitefinity.

Numbering the list items, e.g. .rtsLI1, .rtsLI2, .rtsLI3, etc., would be trivial to implement and provide a lot of flexibility through individual CSS targeting.

This also applies to the RadPanelBar and RadMenu controls.

Please see the ticket here http://www.telerik.com/account/support-tickets/view-ticket?threadid=1010098.

I still need to support IE8 browsers.  The removal of the frameBorder attribute from the iframe rendering causes layout issues in IE8.  Adding a property to the RadPageView project to re-enable this behavior would fix this issue.  It could be false by default in order to pass the cited validation tool.  The developer would have to enable the property in order for the frameBorder attribute to be rendered as frameBorder="0".

Accessibility Insights is reporting invalid markup on all tabs in the TabList.

When consulting the online aria specifications I see that elements with role="tablist" support aria-level="#" where number is > 0.  (https://www.w3.org/TR/wai-aria-1.2/#tablist) However, elements with role="tab" do not. (https://www.w3.org/TR/wai-aria-1.2/#tab)

If possible, we would like to see the aria-level tag moved to the correct page elements in the next release. (Thanks for correcting the aria-level="0" problem previously.) 

I believe this may be the compliance issue Sunil was reporting previously here: https://feedback.telerik.com/aspnet-ajax/1413112-this-ul-should-only-contain-li-elements-without-an-aria-assigned-role

We are using the Telerik tabStrip ASP.NET AJAX control.

We have set PerTabScrolling="true" on the tabStrip.

Then we have hidden a tab on the client side that is apart of the tabstrip.

Now when we scroll to the end of the list we receive a JavaScript error: Sys.InvalidOperationException: Cannot serialize non finite numbers.

This only happens when we hide a tab.

Scenario: RadButton within RadPageView part of RadMultiPageView integrated with RadTabStrip for switching PageViews.

When switching tabs, additional padding is applied to the text in RadButton. After a postback is made, padding is not applied anymore.

In the RadMultipageView a portal URL is set as content. The user navigates to one of the pages within the portal. Now there is no way to go back to previous page or to the default landing page where the tab was initially at.

Requesting a new feature in the tab strip to allow navigate through the iframe history (back/forward) for a multipage view. It could be similar to the back/forward buttons of the browser but within the tab of the tab strip where the content URL is set in the multipage view. This could be set enable/disable by a setting.

The tabs will scroll by themselves even when your finger is off the screen.
