Starting with version 18.1, this legacy Filter Editor is replaced with an updated version that features the advanced "Text" tab, where you can type filter expressions manually. This tab now supports syntax highlighting and auto-complete to facilitate the input. To revert data-aware controls back to the legacy Filter Editor version, disable the static WindowsFormsSettings.UseAdvancedFilterEditorControl property.
