I've set up a grid with a required foreign key by creating a copy of the GridForeignKey editor template and adding .HtmlAttributes(new { required="required" }) and applying that editor template to the foreign key column.
This seems to work nicely however the validation message i get on the grid is "ClientID is required". How do i set this up to refer to the required field by its column title rather than the name in the model.
Thanks
