BarComboBox text search

Hi Bjørnar,

BarComboBox does not currently provide an option to use "contains" matching. Its text search is prefix-based because it is coupled with the control's inline text-completion behavior.

For example, in a font combobox, typing "C" produces "C[alibri]," where the square brackets represent the selected text. You can continue typing to replace the suggested suffix, press Delete to remove it, or press Enter to commit the full value. This is similar to the behavior of Office comboboxes.

If you need to filter contacts by any portion of FullName, the Editors AutoCompleteBox may be a better fit. Its AutoCompleteBoxStringFilter uses "contains" matching by default, and our Bars "ComboBox and Editors" QuickStart demonstrates hosting an AutoCompleteBox within a ribbon or toolbar.

I hope that helps!

The downside is the lack of a command to commit selection/synchronize with selection. Is the contains text search feasible for BarComboBox? I know you're in RC3 so presumably not a last minute addition for the 2026 major releas.

Hello,

Unfortunately, we wouldn't be able to fit any changes into BarComboBox behavior at this time and contains matching would alter the logic flow of how the control currently works.

You could inherit AutoCompleteBox and fire off a command in response to some of its events, like the Submitted event or SelectedItemChanged event.
