I have a pretty large and old application where the user can select the current customer from a combobox. However, the number of customers have grown (>100) to the point where the users think that selecting a customer from the list is awkward.
Does anyone have a good suggestion for a replacement for a CComboBox? The droplist portion should be a multilevel menu or a tree or similar ... I have seen several attempts here and in other places, but they all seem pretty experimental (non-standard UI behaviour, hardcoded drawing functions not utlizing themes, and so on).

You could use the same idea that a lot of websites use, in that they build their lists dynamically as the user types into them. So if the user starts typing a you just load all the customer names from that sub group. Here are some CodeProject articles[^] that discuss the issue.
One of these days I'm going to think of a really clever signature.

Thanks for the input, using some kind of incremental search could be an option.
However, my query was for a custom control with similar functionality as a CComboBox, but where the list box (the dropdown part) is replaced with a tree control or a menu with submenus. There's several examples here at codeproject, but I don't find any of them really cut for the job. It seemed like a pretty common problem, so there should definitely be someone out there having solved it.

Well I guess not since you can't find a sample.

If you could find a ComboBox that expands into CListCtrl, then you can use the grouping feature of the CListCtrl.
But an easier solution is just to use two ComboBoxes. One that allows one to select user type, and one that displays the filtered result within the selected user type.
