I have found a bug in the latest version of the infragistics controls.  

I have solutions that reproduce the issue but it will only let me upload 200KB and my zipped solution without the bin or obj folders is about 600KB.

Please provide a method where I can send you the projects so that you can reproduce the issue.

I have one project that targets SL5 with the latest version of the controls and the other targeting SL4 which has been upgraded with the latest service releases.

General Description:

If you have an autocomplete combobox and type in a search string that reduces the list to more than one item and then select any item other than the top selection, when you cause the combobox to lose focus it re-sets your selection to the top most item from the reduced list.

To reproduce in my sample:

Type in C in the combobox and then select C122, then either tab or click anywhere outside of the control and note how the selection is changed to C77 (the top item in the reduced list)

This bug comes on the back of three other bugs in your combobox control that I have had to deal with in a production system that is being used by thousands of people.

We have been burnt by the selected event firing too many times in 10.3, the selected event firing too many times in 11.2 when add mode was allow, then the measure override with long entries throwing exceptions and now this issue.

Each new version has fixed the previous issues but has introduced new bugs

Please attend to this matter as quickly as possible and let me know when you have a resolution.
