The control should allow customizations in its filtering functionality, for example, the developers should be able let RadComboBox match "Á" when the user types "A".

Allow the developers to style the TextBox area of a editable RadComboBox - add icons, change the string, format the text etc.

It might also be nice to take it one step further and give the option to choose the key that fires an update off

Currently filtering with virtualized RadComboBox is not supported as the filtering feature works with the containers (changes their Visibility).

This would provide the option to stop the auto scrolling when the last item is hovered.

Currently the control scrolls by group.

Available in the 2016 R3 Release.

Combobox with 2 items -- "Item1"   and "it": typing "it" selects the 1st item which is "Item1" and it should select the second one which is "it"

Workaround: use OnDropDownClosed event.

Enable the ComboBox to open its DropDown in up as well as down direction

The combobox lists in Windows 10 settings (see attached pictures) have an interesting behavior which could be integrated by Telerik combox controls. The behavior is as following: when the listbox is opened, it appears above the combobox control with the selected item highlighted. And the placement of the listbox can change if the first item is selected (displayed down direction) or the last item is selected (display up direction).

It's difficult to explain that with simple words, so I suggest to see attached pictures to understand my request.

Currently, the first filtered item of the control is selected once a search (with IsTextSearchEnabled=True) is performed. Users should be able to control whether this happens or if the selection needs to be skipped.

Currently, there is an internal API that determines whether partial matches can be selected or not. Provide public options to change this behavior. By default partial matches are selected.

In the meantime, the default behavior can be changed using reflection to set the CanAutocompleteSelectPartialMatches property of RadComboBox to False.

The RadListBox has an attached property for mvvm binding of SelectedItems - https://docs.telerik.com/devtools/wpf/controls/radlistbox/features/selecteditemssource.

 

Please support SelectedItemsSource for RadComboxBox too.

The RadComboBox control could provide SelectAll button or template functionality. This way the user can choose whether to use the default button or create a custom select all behavior.
