    I am using this code to populate DataBoundListBox
    1.Dim listDatas As New List(Of Ex_Categories)()
    2.        Using db = New n_DataContext(Common.ConnectionString)
    3.        Dim query = Await System.Threading.Tasks.Task.Factory.StartNew(Function() From cat In db.ExCat Order By cat.n_type Select cat)
    4.        listDatas = Await System.Threading.Tasks.Task.Factory.StartNew(Function() query.OrderBy(Function(c As Ex_Categories) c.n_type).ThenBy(Function(c As Ex_Categories) c.cat_name).ToList())
    5.        End Using
    6.LstCategories.ItemsSource = New ObservableCollection(Of Ex_Categories)(listDatas)

    I know how to remove an item from database.
    I want to know how do i remove a selected item from the DataBoundListBox?

    Hi Sanjeewa,

    RadDataBoundListBox will not handle deletion internally. You will need to perform it by yourself. In order to determine which item to delete you can take advantage of ItemTap or SelectionChanging/SelectionChanged events of the control. This will depend on the specific implementation. You can find more details about events in RadDataBoundListBox here.

    Best regards,
