You can create a custom column or you can also check our online documentation on defining CellTemplate/CellEditTemplate for a reference.
As to the filtering, please note it is a data operation which means it is done by building and executing a LINQ query appending proper Where clause over the source collection. Please check our online documentation where the filtering
is explained in details. If you have a custom content for the column, then you can consider specifying a proper FilterMemberPath to be filtered on.
