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

Currently SuggestionView is displayed when the text is updated and the control is focused. There are cases when users need to explicitly set the Text of the control and open the view with the filtered items.

In addition to the string property for NoResultsMessage, add support for using a DataTemplate as well.

Add TextChanged and Completed events when the user enters characters in to the input area.

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.

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

Similar to the UWP AutoCompleteBox functionality - http://docs.telerik.com/windows-universal/controls/radautocompletebox/features/autocompletebox-webservice-support

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