I want to filter a Grid by DateTimeOffset? field
===ADMIN EDIT===
There are two possible options:
1. Use a DTO in which you have a DateTime field converted as desired by your app from the DateTimeOffset. Filtering, sorting, editing, and grouping on DateTime values are supported out-of-the-box.
REPL example that demonstrates this approach.
2. Use the Grid Filter Template. As a filter editor, you can use the DateTimePicker component, which supports the DateTimeOffset type.
