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 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

Now, in WCF binding we return RadListBoxItemData collection which is not consistent with RadComboBox and RadDropDownList controls where we use RadControlNameData object.

Setting EnableEmbeddedSkins="false" in RadGrid when FilterType="HeaderContext" is not applied to the ListBox (filterCheckList) hence the following error is thrown:

Telerik.Web.UI.RadGrid+RadListBoxShared with ID='filterCheckList' was unable to find an embedded skin with the name 'MY_THEME'   

 

 I would like to implement a list picker with item grouping in the destination Asp.Net RadListBox.

Unfortunately the Telerik Asp.net RadListBox control does not seem to support item grouping natively. I have seen a forum post from 2019 that suggests adding custom group items https://www.telerik.com/forums/subheadings-in-radlistbox  We could do this but would prefer a more native solution.

Replicate by dragging a RadListBox item vertically in the Drag-and-drop demo, on a mobile device.

We are using List box item scroll into view to scroll to the item selected in the list box. However, the scroll is not working in the Chrome browser in a UHD touch screen laptop device.

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>

When using:

Value = "(null)"
Text = "(no user)"

as item in the ListBox, the filter must work correctly, and after opening the menu the item should be checked if previously filtered.

Additionally if the item have NULL value instead of "(null)" The visible value must be localized.
