When an Item is selected, the SearchText property should be updated so it shows the item's text. At the moment it stays with the last entered text. The scenario is valid only for Single mode

On start up a Binding error is thrown in the Output for ElementName=WatermarkTextBox.

Available in LIB version 2016.3.1017, it will be also available in the 2016 R3 SP1 release. 

If the AutoCompleteBox is in SelectionMode="Single" editing the text of the SelectedItem will cause the textbox's CaretBrush to go to the end of the text.

While typing, if there's a matching item - it's being highlighted. However, when deleting text, no item gets highlighted even if there is a match.

Make it possible to customize the built-in AsyncFilteringBehavior by inheriting it or it's interface

If the SelectedItem is initially bound to an object and Tab focus passed through the control the text in it disappears.

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.

If you have RadAutoCompleteBox above RadPanelBarItems and the expanded drop down menu (of the RadAutoCompleteBox) covers them, if you click over some of the drop down items the RadPanelBarItem below gets clicked too.
The fix is available in  Q2 2013 Release.

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.

When custom items populating with delay is implemented the first item in the drop down is not highlighted

1. RadAutoCompleteBox with an ObservableCollection set to its ItemsSource

2. The ObservableCollection is populated on the server side once the SearchText of the control changes.

3. The drop down part of the control closes itself even If there are filtered items.

If the control is placed inside ScrollViewer when the mouse is over the AutoCompelteBox control the mouse wheel is handled leading to no scrolling of the ScrollViewer.

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.

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!

AutoCompleteBox cannot be focused on the page load.

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.
