The control should provide support for the JAWS screen readers, which will enable it for use by visually impaired users. More details are available in the following forum thread - https://www.telerik.com/forums/how-is-listbox-usable-for-screen-readers
A workaround is to disable the embedded jQuery and use an older version (for example, 1.11.1 which is the previous version the suite used): https://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/disabling-the-embedded-jquery Repro steps: 1. put a listbox on the page 2. configure it so it does postbacks (e.g., on selection changed, or any other feature) 3. ivnoke said postback (e.g., select an item) Expected: the action is carried off Actual: Firefox throws TypeError: access to strict mode caller function is censored Sample markup <telerik:RadListBox runat="server" ID="rlb1" OnSelectedIndexChanged="rlb1_SelectedIndexChanged" AutoPostBack="true"> <Items> <telerik:RadListBoxItem Text="first" Selected="true" /> <telerik:RadListBoxItem Text="second" /> </Items> </telerik:RadListBox>
RadListBox allows to declaratively bind the Text and Value properties of the ListItems, e.g: <telerik:RadListBox runat="server" DataTextField="Text" DataValueField="Id"> Unfortunately, this is not possible for the ImageUrl property. My Suggestion: please allow to also bind the ImageUrl declaratively as known from other controls, e.g: <telerik:RadListBox runat="server" DataTextField="Text" DataValueField="Id" DataImageUrlField="..." // and maybe even like this: DataImageUrlFormatString="..." DataImageUrlFields="...">
Hi, Would love to have feature for reorder animation and drop placeholder when user is reordering the item(s) in the Radlistbox. A example would be the list in invisionapp.com as attached. Another example would be like JQUERYUI's sortable plugin. URL: https://jqueryui.com/sortable/#placeholder. Thanks.
The error is observed when an item that is added from the client-side is to be transferred to other RadListBox from a RadListBox that is loading on demand. Unfortunately the control supports such scenario only when that transfer is made from the server side.
