How to add valdation to a webgrid?

I wonder how I add validation to a webgrid. Take as example this:
ID, Date

now Date should be treated as Date how can I enforce that in a WebGrid?

Regards
Friedrich

Add fields with #column:addBlock: instead, like:

        column: 2 addBlock: [:object |
          field := WebInputField aspect: #date for: object.
          field validIfTrue: [:value | "validate date here"].
          field].

Best regards
