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.
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 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.
