  • RadListBox supports items reordering via the reorder buttons and drag and drop.

    To enable the reordering functionality you need to set the AllowReorder property to true. After doing that, the reorder buttons will appear.

    To enable reordering via drag and drop you also need to set the EnableDragAndDrop property to true.

    If you want RadListBox to postback after reorder set the AutoPostBackOnReorder property to true.

    In case you want to enable reordering only via drag and drop you can hide the reordering butons by setting the ShowReorder property to false: 

    <telerik:RadListBox AllowReorder="True" EnableDragAndDrop="True">
	<ButtonSettings ShowReorder="False" />
</telerik:RadListBox>
