At the moment, one of the columns has no filter. In my model, that column is a collection of strings. For the grid, I append them together separating by a comma.
John Doe, new List("Apples", "Oranges")
In my grid, it appears as "John Doe" in the first column and "Apples, Oranges" in the second column.
In my database, I do have a collection of all the tags, I was wondering if I can create a custom filter such that it'll check if it contains the tags I select to filter by.
