    <Items>
        <telerik:RadComboBoxItem Text="Item 1" />

    </Items>
</telerik:RadComboBox>

Hi Ken,

Thank you for reporting the problem. I think we will be able to fix this issue and ship it with the next release. Until then, you may use the workaround below.

Workaround

Add the following script on the page where the Combo is located. Must be placed after the ScriptManager declaration.

<script>
    Sys.Application.add_load(function () {
        var combo =  $find("<%= RadComboBox1.ClientID %>");

        $(combo.get_inputDomElement()).attr('aria-readonly', combo.get_readOnly());
    });  
</script>
