I think in the end it depends on what your validation needs are.

In my case, Cell Value Changed has done what I wanted/needed.

If the entered value doesn't match your custom criteria, set the event's Valid parameter to false.

The problem I am having is how to refactor logic to an external class, that has references to the winform controls.Form All following code is part of private string last Edited Cell Value; private void dgv Replenish_Cell Begin Edit(object sender, Data Grid View Cell Cancel Event Args e) private void dgv Replenish_Cell Validating(Object sender, Data Grid View Cell Validating Event Args e) private void dgv Replenish_Cell Clicked(object sender, Data Grid View Cell Event Args e) private void dgv Replenish_Cell Formatting(object sender, Data Grid View Cell Formatting Event Args e) private void dgv Replenish_Cell Value Changed(object sender, Data Grid View Cell Event Args e) The truth is, it's really very hard to refactor this code out of the code behind once it's been written like this.While handling the Validating Editor event, you may need to identify the current row and column. After the automatic validation has been performed, the Validating Editor event is raised.Handle this event to implement custom constraints on cell values.The cell value should be grater than zero and less than 1,000,000.

The default event handling result (displaying an error icon and tooltip leaving the editor focus unchanged) can be overridden by handling the Invalid Value Exception event.

The following example prohibits invalid "col Budget" column cell value assignment.
