After selection autocomplete uses the data within TextSearchPath for display. We search many fields so this output is less than ideal. DisplayMemberPath or a SelectedItemTemplate would be better.
Declined: With its current implementation, the control behaves correctly with the explained setup. You can compare it to the WPF editable ComboBox control - it displays the items with the DisplayMemberPath and searches them and displays the selection through the TextSearch.TextPath property. Please check the attached sample project that demonstrates the explained above. Regards, Kalin
