RadComboBox Bootstrap Lightweight skin is not loading in version 2022.3.913

Workarounds provided by Admin:

Option 1

Use RadStyleSheetManager to load the correct stylesheet from Telerik.Web.UI.Skins assembly, as per the instructions in Skin registration with RadStyleSheetManager:

<telerik:RadStyleSheetManager runat="server" ID="RadStyleSheetManager">
    <StyleSheets>
            <telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.BootstrapLite.ComboBOx.Bootstrap.css" Assembly="Telerik.Web.UI.Skins" />
    </StyleSheets>
</telerik:RadStyleSheetManager>

Option 2

Link the correct stylesheet manually on the page in one of the following ways:

• By using the attached stylesheet file.
• Via the Telerik CDN link: https://d35islomi5rx1v.cloudfront.net/ajaxz/2022.3.913/BootstrapLite/ComboBOx.Bootstrap.css

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;
	}
}

In ComboBox If somehow focus is moved to dropdown element (e.g. when user clicks on a header, or on load more items button) then arrow keys and keyboard support won't work anymore.
It can be fixed by simply setting dropdown tabindex to say 1 and attaching ComboBox's own _onKeyDown handler to dropdown keydown too.

A possible workaround would be tweaking the ItemRequestTimeout property of the ComboBox

<telerik:RadComboBox ItemRequestTimeout="380" runat="server" ... >
        ...
 </telerik:RadComboBox>

If the same text is typed into the input field as the one set for EmptyMessage and page is submitted, validator evaluates True.

Current workaround is to subscribe the RadComboBox to OnClientFocus client event handler, and clear the EmptyMessage manually, thus preventing the EmptyMessage text to be sent to server.

<telerik:RadComboBox ... OnClientFocus="comboFocus">

<script type="text/javascript">
	function comboFocus(sender, args) {
		sender.set_emptyMessage("");
	}
</script>

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.
