I created a tutorial topic about filtering TRichViewEdit columns in TcxGrid: https://www.trichview.com/forums/viewtopic.php?t=12440

That's all about filtering. This information can be found (in a compact form) in the comments at the beginning of cxTRichViewFilter.pas. PS: by the way, you can see one more new feature: sorting.

If you try to type something above the product values, nothing is matched the updated filter string. The reason is similar to the problem with the check list items. The grid creates TRichView...

How to match a filter with a display text instead of a raw value? We need to assign TableView.DataController.Filter.CompareByDisplayValues := True...
