Thank you for your cooperation.
I have researched further the issue. Since you have set CanAutocompleteSelectedItems=False
, this means that the autocompleted item won't be selected, and that is way when pressing the arrow key the first item is highlighted, as since there is no currently selected item, the ComboBox selects the first one in the list. This is the expected behaviour. If you set the property to True
you will achieve the desired behavior.
Here is the description of this property for reference:
"Gets or sets the value specifying whether typing a text in RadComboBox should change the selection."
Hope this information helps and that the issue is resolved. Please let us know if you have any other concerns about our controls.
