I did try this code, and there were no design time or run time errors, but it did not trigger the validation for the GridEditor Column.
In the same grid there are declarative validators for a text box and a combo box, which do fire as expected, so all seems to be OK ajax-wise.
I guess could revert to a template column and a radcombobox, but it seemed more elegant to use the special column provided.
Has anyone got the validation working for this column type?

The purpose of the GridHTMLEditorColumn is to display HTML and not to validate controls. When editing the content of this column you are editing the HTML in the field. If you want to put controls in a column I suggest that you use GridTemplateColumn instead. By doing so you would be able to validate the controls inside.
