RadComboBox Autocomplete

[Broken]

I can't figure out how to implement autocomplete functionality using your ComboBox.

In XAML I have:
<telerik:RadComboBox IsEditable="True" ItemsSource="{Binding ItemList}" Text="{Binding ItemText, Mode=TwoWay}"/>

In ViewModel I have:

        private string _itemText;
        public string ItemText
        {
            get { return _itemText; }
            set
            {
                _itemText = value;
                RaisePropertyChanged("ItemText");
                GetItems();
            }
        }
        private ObservableCollection<Item> _Items;

        public ObservableCollection<Item> Items
        {
            get { return _Items; }
            set
            {
                _Items = value;
                RaisePropertyChanged("Items");
            }
        }
        private void GetItems()
        {
            _service.BeginGetItems(ItemText, 0, (ar) => Items = _service.EndGetItems(ar), null);
        }
And of course this doesn't work because autofill will messup ItemText, there should be some kind of SearchText property on Combobox which contains text without autofill to which I can bind to, but I have not found one.

You are right, you need a propertly like SearchText in order to use custom autocomplete, but RadComboBox does not have such property yet.

The best that you could do is to disable the integrated autocomplete and the filter and implement a custom filter, like the attached application.

Hi,

Is the solution presented in this forum still the most up to date method of achieving on demand loading with the Silverlight RadComboBox?
If not please provide an updated example.

Thanks
