Please see demo: https://demos.telerik.com/aspnet-ajax/monthyearpicker/accessibility-and-internationalization/wcag-2.0-and-section-508-accessibility/defaultcs.aspx

1. tab to calendar button

2. hit enter to open calendar dialog

3. press tab

Notice that instead of causing the focus to move within the calendar pop-up, focus first shifts through all remaining elements of the underlying page. This make this control difficult for users relying solely on keyboard navigation.

Ideally this control should function more like the standard calendar controls, obtaining focus when opened and returning focus to the date field when closed.

We use the Telerik RadGrid for our application and we have found that if we click on the filter button on the RadGrid, it will make the page scroll.

Reproduction steps:

Go to the Telerik demo at https://demos.telerik.com/aspnet-ajax/textbox/overview/defaultcs.aspx
In the Comment box, type "one two".  Do not let the textbox lose focus.
Highlight "two" and start to drag it to move it before "one". The other text ("one") will disappear, and is gone forever, as far as I can tell.

It can be also reproduced with this configuration:

<telerik:RadTextBox RenderMode="Lightweight" runat="server" ID="RadTextBox3" Width="200px" EmptyMessage="Enter comment" TextMode="MultiLine" Height="100px" Resize="None"></telerik:RadTextBox>

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.

Problem:  Latest Telerik version of Combobox or RadCombobox reads "readonly" though it's not, when EnableAriaSupport is enabled.

Details: 

url to test with JAWS - https://demos.telerik.com/aspnet-ajax/combobox/examples/wai-aria-support/defaultcs.aspx

When I use JAWS to read the combobox present on this demo it reads as follows - 
              ComboBox readonly - Alice Mutton. To change the selection press the arrow keys.

Over here, why JAWS is reading "readonly". It's not readonly. It's making our screenreader blind users confusing.

I drilled down more into the problem and found that, the input element below has the aria-readonly=true set though the combobox is not readonly.
Here is the html generated for above combobox from telerik demo site -

<input name="ctl00$ContentPlaceholder1$RadComboBox2" class="rcbInput radPreventDecorate" id="ctl00_ContentPlaceholder1_RadComboBox2_Input" role="combobox" aria-busy="false" aria-disabled="false" aria-expanded="false" aria-haspopup="true" aria-readonly="true" aria-owns="ctl00_ContentPlaceholder1_RadComboBox2_listbox" aria-autocomplete="none" type="text" readonly="readonly" value="Alice Mutton" autocomplete="off">

I understand that this input control should be readonly so that aria users should not type and go haywire. But looks like to maintain the readonly=readonly property, telerik is generating aria-readonly=true for this _Input control and resulting this issue.

When you change this attribute aria-readonly="true" to aria-readonly="false", JAWS read it correctly as follows - 
              ComboBox - Alice Mutton. To change the selection press the arrow keys.

Let me know how to achieve that so that users will not be confused.

Issue seems to happen with RadGrid with Bootstrap Skin, RenderMode Lightweight when RequireFieldValidator is enabled in combination with Batch Editing.

Other skins seems to have it right.

Hi, I have trouble with RadScriptManager. I would like combine scripts on page to only one file. But when I enabled it, my site threw javascript error on loading.
Please help me fix it, it would also be better if you can help me understand what happened.

First image is what I set up for RadScriptManager

Secondary image is the error.



I have no idea what's Telerik.Web.UI.Point, I haven't used it anywhere.

Please help me get this error out & fix it.
Thank you.

Hi,

For the date picker and it's family of controls (time picker, date time picker), when using bootstrap skin, lightweight rendering and RTL page, the buttons for the picker are displayed on the wrong side of the control (the right side) instead of being displayed on the left side. I know this can be fixed using some CSS but although the html controls are in order (text and then button both in a container with RTL), the button is stuck to the right side somehow

please advise

The role=textbox is set to the wrapper element instead of the input element itself. That confuses the screen readers such as JAWS, which leads to the Form Fields dialog to skip them. 

As a temporary workaround, the role of the wrapper element with class RadInput can be set to "presentation"

<script>
    function pageLoadHandler() {
        $telerik.$(".RadInput").attr("role", "presentation")
        // Sys.Application.remove_load(pageLoadHandler);  
    }
    Sys.Application.add_load(pageLoadHandler);
</script>

Or using the following script: 

var WebARIAHelper = (function ($) {

  // Assign default ARIA roles to desired elements
  function AssignDefaultARIARoles(element) {
    element = (element || document.body);

    // TFS 110547 - Mark SPAN/DIV around RadInput elements as presentation to avoid confusing JAWS form field dialog
    $("span.RadInput, div.RadInput", element).attr("role", "presentation");
  }
  
  // Handle AJAX EndRequest event to process any new content
  function WebARIAHelperEndRequestHandler(sender, args) {
    if (args.get_error() == null) {
      // Make sure all page controls can finish their ready event processes before looking at DOM
      window.setTimeout(function () {
        AssignDefaultARIARoles();
      }, 10);
    }
  }
         
  $(function () {
    // Make sure all page controls can finish their ready event processes before looking at DOM
    window.setTimeout(function () {
      AssignDefaultARIARoles();
    }, 10);

    if (window.Sys && Sys.WebForms && Sys.WebForms.PageRequestManager) {
      var instance = Sys.WebForms.PageRequestManager.getInstance();
      if (instance) instance.add_endRequest(WebARIAHelperEndRequestHandler);
    }
  });


  return null;
}
)($ || $telerik.$);

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:
CharacteristicValue
Used in Roles:
Inherits into Roles:

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

When you have both a Detail Item Template and a Detail Table inside a Grid and then when you show a hidden column using the context menu it only shows for the first row and the grid doesn't display properly.  It also throws the javasecript error "Unable to get property '_getVisibleColumnsCount' of undefined or null reference".

Images with "*.jpeg" extension are saved as "*.jpg" in a different file even if the "Overwrite" option is checked. 

Steps to reproduce:

1. Open an image with "*.jpeg" extension in ImageEditor (e.g. test.JPEG)
2. Edit the image
3. Open the Save Dialog and choose "Save Image On Server" with checked "Overwrite if file exists?" option

Result: The edited image is saved as a new files with jpg extension (e.g. test.jpg)

We are evaluating whether to use Telerik to redesign a legacy web app written using an old version of Telerik.

After downloading Trial version on fresh install of windows, I can't add ajax control to form. `I am using visual studio 2019, this is the first version of Telerik installed on this computer.  I just get the "Error Creating Control RadScriptManager1. They do show up in the toolbox so this surprises me.

Very latest version.

Could it be a license issue?
