Customer feedback:

The first combobox below behaves as I would expect to, and resizes when the browser window is resized.  However, the second combobox does not resize when the browser window does.  They use the same skin.  The only real difference that I can see is that I use check boxes in the second one.

In the meantime you can use the following css workaround that will fix the issue: 

.rcbAutoWidthResizer .rcbScroll {
	overflow: visible !important;
}
 
/*To target IE 6, 7 and 8*/
@media \0screen\,screen\9 {
	.rcbAutoWidthResizer .rcbScroll {
		overflow: auto !important;
	}
}
 
/*To target IE 9 and 10*/
@media screen and (min-width:0\0) {
	.rcbAutoWidthResizer .rcbScroll {
		overflow: auto !important;
	}
}

See: https://demos.telerik.com/aspnet-ajax/combobox/examples/accessibility/defaultcs.aspx

1. Click somewhere in the page to establish focus.

2. Use the tab key to focus the combo box.  (This works in Chrome, but in IE the control is skipped.)

3. Note that the combo box does not drop-down the list of options like it does when you click the mouse. Clicking the enter key does not drop down the list. Alt-Down-Arrow does not drop down the list.

4. Press Tab and note that focus skips the arrow icon on the combo box and moves down to the "validate with Wave" link.

5. Press Shift-Tab and note that the Arrow icon is now focuses and the enter key will drop down the options list.

6. While JAWS 2019 is running, press the "C" key and note that JAWS reports that there are no combo boxes on the page.

 

Expectations:

* Jaws is able to properly identify the combo box based on ARIA tags

* Tabbing into the combo box presents the same behaviors as using the mouse button

We are running HTML validators as part of an effort to attain WCAG 2.0 A compliance.

Among the errors we are seeing is

The summary attribute is obsolete. Consider describing the structure of the table in a caption element or in a figure element containing the table; or, simplify the structure of the table so that no description is needed.

Here is a snippet of the failing HTML, apparently from the rendering of the RadSocialShare control:

	<div id="ctl00_TemplateBody_WebPartManager1_gwpciNewSocialShareCommon_ciNewSocialShareCommon_RadSocialShare1_compactPopup_C_comboBox" class="RadComboBox RadComboBox_Default" style="width:160px;">
<table summary="combobox" border="0" style="border-width:0;border-collapse:collapse;">

We are currently running version 2013.2.717.45 of the ASP .NET for AJAX controls, but we just tried 2013.3.1015.45 and it didn't fix things in this regard, either.

There is a similar discussion at http://www.telerik.com/community/forums/aspnet-ajax/combobox/table-summary-attribute.aspx , which recommends a jQuery fix.  This fix works in terms of removing the summary attribute from that table, but it does not result in clean HTML when the w3c validator is run against it, so we believe that is not an acceptable workaround.

In the discussion at http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/accessibility-issues-various.aspx , some mention is made of fixing the combo box for the 2012 Q3 release, but it doesn't look like that happened.

Release R3 2019
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.

Release R1 2022

<telerik:RadComboBox runat="server" ID="CB" AllowCustomText="true" HighlightTemplatedItems="true" EnableViewState="false" CheckBoxes="true" EnableLoadOnDemand="true" OnItemsRequested="CB_ItemsRequested" ></telerik:RadComboBox>

Specifically, note that CheckBoxes is true.

In some cases, the combo box's  item's text may have HTML tags in them, but we don't want that HTML to be interpreted, and we're happy that RadComboBox automatically encodes the Item's name.  For example, the Item's text might be <img src=xxx onerror=alert(0)> , and of course we don't want that javascript to run. 

However, we have found a case where the text is not properly escaped, in which case the javascript does run and the alert popup shows.  The error is in RadComboBox.CheckBoxes.js, in the _checkedItemsTextsFitInputWidth function.  That function is passed the comma separated string of all the selected item's text.  This function wants to measure the width of the string, and so it creates a div off-screen, and then pushes the checkedItemTexts string into the div.  If the checkedItemTexts string contains any HTML tags that contain javascript, then that javascript is executed, which can be a XSS attack.

When EnableAutomaticLoadOnDemand="true" is set and no Height is specified, the first time RadComboBox is expanded only the topmost 3 or 4 items are visible.
The rest of the items become visible when they are hovered or if the ComboBox is expanded again.

If we dynamically remove highlighted item from a ComboBox at clientside, afterwards get_highlightedItem still returns that deleted item.
ComboBox takes care of deleting selected item at like 497 of RadComboBox.js. Highlighted item should be taken care of too.
