Allow customers to easily take the user input and trigger custom searching algorithm and assign the results to the ItemSource of the AutoComplete.

Available in R3 2018 release as part of the feature-set of the new and improved RadAutoCompleteView control, for more details refer to: https://docs.telerik.com/devtools/xamarin/controls/autocompleteview/autocompleteview-overview

Currently it is not possible to initialize the tokens of the autocomplete so the UI shows already selected tokens.
This is necessary to use the control for a CREATE/EDIT scenario.

Example:
- Create an event (party) and select all the friends from the autocompelte (another issue is that already selected tokens cannot be removed from the suggestion list)
- Save the event
- Edit the event => now you would need to see the already selected friends so you can add and remove some

When receiving or losing focus, the Focused, Unfocused and FocusChangeRequested event handlers are not executed.

Observed in Android and iOS

There does not seem to be an easy way to modify the custom message shown when no result is found in the AutoComplete control. We can expose a property similar to the Watermark one. 

Edit: Avalable in R3 2017 SP release.

I have a page where many AutoComplete controls are used. Selecting a value in one must select a value in another. We know that this value is selected by setting Text property (through object binding), but by doing this, suggestion view shows up.
I test many tweaks with ShowSuggestionView property, SuggestMode, or whatever, and there is no proper way to achieve the behavior I want.

As to the concrete feature go to: https://docs.telerik.com/devtools/xamarin/controls/autocompleteview/autocompleteview-methods

Currently the Text property can only be get. Expose it as setter as well.

Avalable in R3 2017 SP release.

Currently users are not aware when a token gets selected/deselected.

If you're binding AutoComplete's Text to a view model property, the initial value doesn't show. It only updates after the bound string is set after the control is loaded.

Repro:

VIEWMODEL
private string enteredText = "Hello World 1";
public string EnteredText
{
    get { return enteredText; }
     set { enteredText = value; OnPropertyChanged(); }
}

VIEW

<telerikInput:RadAutoComplete Text="{Binding EnteredText}" />



WORKAROUND

private void AutoComplete_OnNativeControlLoaded(object sender, EventArgs e)
{
    (BindingContext as ViewModel).EnteredText = "Hello World 2";
}

Available in the R2 2018 release.

When the value of Text is set in XAML, Text value is ignored on Android. Use this example:

<telerikInput:RadAutoComplete x:Name="autoComplete" Text="Initial Text" Watermark="watermark" />

Observe that only the watermark appears (note: this issue happens with or without watermark).


Workaround:

Set the value of Text after view has loaded, for example in OnAppearing:

protected override void OnAppearing()
{
    base.OnAppearing();

    autoComplete.Text  = "OnAppearing";
}

By default, the SuggestionView should appear when the Text is changed and the control is focused.

Allow users to define custom filtering logic, for example, to search in a few properties.

When there are enough tokens to wrap them on a second row, the control hangs and application eventually crashes.

Available in minor release 2017.3.927. It will also be available in the R3 2017 SP release.
