Filter row

Custom Filter dialog

Let's try another dialog: Custom filter. To display it, we need to remove a date-related condition (to make a filter simpler), to click on the filter icon in "Product" header, and select the "(Custom...)" item. CustomFilter.png And it works for Markdown data: CustomFilter - Appli...

Filtering by display text. Filter created in code. How to activate filtering

The filter is not matched because the grid compares the filter string not with the display text, but with the raw value. In our case, with Markdown code. How to match a filter with a display text instead of a raw value? We need to assign TableView.DataController.Filter.CompareByDisplayValues := True...
