How can I validate the cells in a DataGridColumn individually? The validation is configured per-row. For example

FIELD               VALUE   TYPE
age                 13      Integer
height              13x3    Integer
registered          true    Boolean
temperature         98.G6   Float

In this case, of course 13x3 and 98.G6 would be invalid.

mockup

Writing a Validator is no problem, and I can grab the TYPE from the data provider object, but now do I get individual access to the GUI cells so I can give the Validator a source which is an individual cell, set the errorString on an individual cell.
