I have a DGV with Several Columns. One is a date column. User can enter 01/01/2014 format or March 2014 format or Spring 2014 format or "Unknown". If I click the header it does sort by 01/01/2014 format but then if it is in the format of "March 2014" it becomes out of order because it does is alphabetically. SO my question is do I have to create a custom sort code or how do I fix this?
