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".

Where we use the ShowBaseLine property in Horizontal Orientation, the same feature is not available when in Vertical Orientation

Hi Telerik team,

 

Few of our clients reported the following issue with respect to WCAG 2.0 SC 4.1.2 standard. (508 Standard and compliance) -

PracticeFunction (example)
Ensure ARIA roles, states, and properties are validLI has an aria-level attribute of 0, which is not an integer value greater than, or equal to, 1

 

Example: visit https://demos.telerik.com/aspnet-ajax/tabstrip/examples/wai-aria-support/defaultcs.aspx 

 

Observe the ul-li elements created for tabstrip. On each li element, there is aria-level attribute whose value is set to 0.

As per WCAG this value should start from 1. The value 0 is invalid. Refer: https://www.w3.org/TR/WCAG20-TECHS/ARIA12.html

 

Please let me know when are you going to fix this for compliance.

Few of our clients reported the following issue with respect to WCAG 2.0 SC 4.1.2 standard. (508 Standard and compliance) -

 
Practice Function (example)
Ensure sub-lists are marked up properly This UL should only contain li elements (without an ARIA-assigned role), script elements (without an ARIA-assigned role) or template elements (without an ARIA-assigned role); or
 
elements with a role=listitem attribute; as direct child elements

 

Example: When Telerik Tabstrip has EnableAriaSupport=true, internally tabstrip is combination of ul-li with css to display the Tabs properly -

The html looks like as follows -  

<ul class="rtsUL">
    <li class="rtsLI rtsFirst" role="tab" aria-disabled="false" aria-level="0" aria-controls="LayoutPageView">
        <a accesskey="L" title="Layout" class="rtsLink rtsBefore" id="LayoutTab" href="#"><span class="rtsOut">
            <span class="rtsIn">
                <span class="rtsTxt">
                    <h2 class="RadTabStrip RadTabStrip_Default"><u>L</u>ayout</h2>
                </span>
            </span>
        </span>
        </a>
    </li>
    <li class="rtsLI" role="tab" aria-disabled="false" aria-level="0" aria-controls="SearchPageView" aria-selected="true" id="SearchTabStrip_active_tab">
        <a accesskey="S" title="Search" class="rtsLink rtsSelected" id="SearchTab" href="#">
            <span class="rtsOut">
                <span class="rtsIn">
                    <span class="rtsTxt">
                        <h2 class="RadTabStrip RadTabStrip_Default"><u>S</u>earch</h2>
                    </span>
                </span>
            </span>
        </a>
    </li>
    <li class="rtsLI rtsLast" role="tab" aria-disabled="false" aria-level="0" aria-controls="ResultsPageView">
        <a accesskey="R" title="Statewide Search Results 0 records" class="rtsLink rtsAfter" id="ResultsTab" href="#">
            <span class="rtsOut">
                <span class="rtsIn">
                    <span class="rtsTxt">
                        <h2 class="RadTabStrip RadTabStrip_Default">Statewide Search<u>R</u>esults (0)</h2>
                    </span>
                </span>
            </span>
        </a>
    </li>
</ul>


Observe the aria attributes which are on li elements. Is that really necessary considering the compliance? (as mentioned in practice and example).

 

Please let me know when are you going to fix this for compliance.

Only the selected tab has an aria-selected attribute. According to the documentation I can find, all tabs should have aria-selected, and be set to true or  false as appropriate.
https://www.w3.org/TR/wai-aria-1.1/#aria-selected

aria-selected (state)§

Indicates the current "selected" state of various widgets. See related aria-checked and aria-pressed.

This attribute is used with single-selection and multiple-selection widgets:

  1. Single-selection containers where the currently focused item is not selected. The selection normally follows the focus, and is managed by the user agent.
  2. Multiple-selection containers. Authors SHOULD ensure that any selectable descendant of a container in which the aria-multiselectable attribute is true specifies a value of either true or false for the aria-selected attribute.

Any explicit assignment of aria-selected takes precedence over the implicit selection based on focus. If no DOM element in the widget is explicitly marked as selected, assistive technologies MAY convey implicit selection which follows the keyboard focus of the managed focus widget. If any DOM element in the widget is explicitly marked as selected, the user agent MUST NOT convey implicit selection for the widget.

Characteristics:

Used in Roles:
Inherits into Roles:

falseThe selectable element is not selected.
trueThe selectable element is selected.
undefined (default)The element is not selectable.

Workaround is attached. It focuses the first focusable element on the page and you can easily change that logic.


We have already taken upon ourselves the task of managing the keyboard navigation in a container (the pageview).

Please leave your comments how this should be fixed, because there are many options. For example:

   -  we can focus the first focusable element, in a fashion similar to the workaround. Caveat: the list is incomplete, there are more focusable elements. Also, non-sequential tabIndex values set by the developer will not be honored. We may implement logic that counts the tabIndexes and focuses the smallest one, but this is complex, error prone and browsers tend to return bad values for this attribute, especially when it is set to -1. Also, this may not be the desired behavior by the developers.

    - we can focus the pageview element. Caveat: you may be unable to enter its child inputs at all, depending on the page setup and the tabIndex values.

    - we can consider setting tabIndex to -1 for all focusable elements in other pageViews akin to the modal backgrounds for controls like window and tooltip. The goal being to let the natural flow of the page take over and the browser to do this job, not our JS code. Caveat: we can still break the navigation logic on the page and this also has low performance when changing many tabIndex attributes at once.

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.

Observe the below video, demonstrating the issue :

http://screencast.com/t/pC1V29UwYQ83 

Adding another, not visible textarea to absorb the focus can be used as a workaround:

<telerik:RadTabStrip ID="rtsRFT" runat="server" Skin="Office2007" MultiPageID="rmpRTF"
    SelectedIndex="0" ShowBaseLine="True" OnClientTabSelected="OnClientTabSelected">
    <Tabs>
        <telerik:RadTab Text="Description" TabIndex="61" ToolTip="Click to view description"
            SelectedCssClass="SelectedTab" PageViewID="pDesription">
        </telerik:RadTab>
        <telerik:RadTab Text="Notes" TabIndex="63" ToolTip="Click to view notes" PageViewID="pNotes">
        </telerik:RadTab>
    </Tabs>
</telerik:RadTabStrip>
<div class="welcomeTab" style="height: 100%">
    <telerik:RadMultiPage ID="rmpRTF" runat="server" SelectedIndex="0">
        <telerik:RadPageView ID="pDesription" runat="server">
            <div>
                <telerik:RadEditor ID="txtDescription" runat="server" Width="100%" Height="250px">
                </telerik:RadEditor>
            </div>
        </telerik:RadPageView>
        <telerik:RadPageView ID="pNotes" runat="server" Height="100%">
            <div>

            </div>
        </telerik:RadPageView>
    </telerik:RadMultiPage>

</div>

<script type="text/javascript">
    function OnClientTabSelected(sender, args) {
        $telerik.$("#inboxId").focus();
    }

Please see the following Forum topic and attached images:

http://www.telerik.com/forums/multi-row-tabs#i-uWt1OdnEKceUHt32s43Q

We would consider this to be a bug, and the response we received back from Ivan Danchev was less than satisfactory given that this topic is now over 5 years old.

Please consider adding this to your roadmap and addressing this behaviour sometime in the near future.

Currently the RadTabStrip + Google Maps integration suffers a limitation e.g. if the map is within a hidden tab, there are displacements.

1)If already one tab opened means-->just i want to select tab(without postback)

for that me use set_selected(true) and select().But its also fires OnClientTabSelected Client Side API function.

So how can i achieve this?

 OnClientTabSelecting function available to get focus of user select a tab.Becoz i want two functionality

1)I want  postback for some specific of the tabs when user clicks already opened tabs

2)I want to select a Tab(without postback) when user clicks from Leftmenu(RadPanelBar)

Pls explain with sample code how to achieve both Its very urgent

3) In my left side user control  RadPanelItem me used.Based on this only tabs are opened based

Functionality me need -->whenever user select a already opened tabs its corresponding menu also should select in RadPanelbar(PanelItem)

Me tried this logic
============
function ClientTabsSelected(sender, args) {
var tab = args.get_tab();
GetItemText(tab.get_text());
}

    function GetItemText(currenttabtext) { //This function me put left side user control.

          var panelBar = $find("<%=RadPanelBar1.ClientID%>");

           var currentitem = panelBar.findItemByText(currenttabtext);

           if (currentitem) {
               currentitem.set_selected(true);
               currentitem.expand();
          }

      }
================================

Its works only when panelitem expand.If already selected item in Panelbar collapsed means.Its select properly (rpSelected CSS Class assigned  me find using inspect element)

But its not expand..Please help me solve this also

Please response soon.Its very urgent
