Both versions of the control have a usability problem for our users:
If the Telerik control already has a selected option, and if you open the Telerik control via mouse, then start typing, it appends your text to the end of the current selection, instead of replacing it. This is not what the user intends. The user wants to find a match for the text they are entering in, not the previous selection + their typed-in text.
It works OK if you tab to the dropdown via keyboard and start typing (it highlights then replaces the current selection with your typed-in text), but not if you activate the dropdown via mouse first and then start typing (it appends your typed-in text to the current selection)
This situation also happens if you then make a different selection in the dropdown (via keyboard or via mouse) and then start typing again (your cursor is at the end of the existing selection).
On Telerik’s website, the demos have the same problem. Has anyone developed a solution to this problem?
Note: For our implementation of AutoComplete, MarkFirstMatch is True and AllowCustomText is False. Because the text is added to the end of the current selection, there is no valid match and user does not see the text they are typing. This makes the situation even more frustrating to the users (it seems like the dropdown is unresponsive.)
