Similar to BoxesItemTemplate when SelectionMode=Multiple. Perhaps switch between modes of text entry and SelectedItemTemplate. This would allow a custom display of the selected item and the ability to re-enter search by text mode. It might be nice if the type search text stayed so if you mis select- simply clicking the search text would get the user back to the same filtered list pre-mis-select.
Steps to reproduce: 1. Run the attached sample application 2. Enter the value that is not on the list of autocomplete values. 3. The RadAutoCompleteBoxAutomationPeer.Value return null, because the value is not included in SelectedItems collection If the entered value is included in the list, the RadAutoCompleteBoxAutomationPeer.Value contains a comma (',') in single selection mode. Workaround: 1. The first approach is getting the value from nested watermark text box 2. Another approach is creating own AutomatomationPeer that getting the value from SearchText
In Multiple SelectionMode it would be useful to be able to customize the way selected items (boxes) are displayed. Customizing their looks via a StyleSelector would be optimal.
Make it possible to customize the built-in AsyncFilteringBehavior by inheriting it or it's interface
The default behavior when the focus is inside an input control and it's Text is changed is that it's caret is placed in the beginning of the next text. This could be observed in the WPF TextBox control. In certain scenarios modifying the SearchText while the focus is inside the control is a desired behavior. In those scenarios the caret position is expected to be set to the end of the new text which is set to the SearchText property.
e.g. AutoCompleteBox is in SelectionMode="Single" has 3 items - "Item 1", "Item 2", "Item 3"When the user enters "Item 1" with keyboard, the control should select this item.

Make it possible to display text e.g. "No result" when there are no filtered items. Here is an example of this http://i.stack.imgur.com/HVaxP.png Available in the R3 2016 Release.

When I type some characters, an item is always selected (generally the first if we don't create an highlightbehavior), but when I delete a character, no item is selected even if the list contains items. It would be awesome if the behavior of a character removing can be the same than the behavior of the character typing. So I would like, after a charater removing, that an item is always selected when the filtered list contains at least one element. Thanks for this feature!
Add a possibility to set minimum populate delay to the control. It would be useful if a property like MinimumPopulateDelay is available to be set which would cause the populating of items to be delayed. Such feature would be helpful for cases when making requests to web server etc.
When the drop down portion part of the control is opened and there is a highlighted item when backspace gets pressed the highlighted item is cleared.
The documentation for WPF FilteringBehavior.FindMatchingItems, <http://docs.telerik.com/devtools/wpf/api/html/M_Telerik_Windows_Controls_FilteringBehavior_FindMatchingItems.htm>, only tells the type of the parameters. It does not tell what the parameters do, nor does it tell what the function does.
As a developer I would like to be able to implement a custom highlighting logic of the items in the DropDown portion of the control so that I could implement a "best" matched item highlighting.
For example changing the highlighted index to be the first possible in SuggestAppend AutoCompleteMode.
