    Have simple model with RegularExpression attribute. This attribute correct work with unobtrusive validation.

    public class PersonModel
        public int PersonId { get; set; }
        public string Phone { get; set; }

    Render data in Grid. 

        .DataSource(src => src.Ajax()
            .Model(model => model.Id(p => p.PersonId))
            .Read("_GetPersons", "Account")
            .Create("_CreatePerson", "Account")
            .Update("_UpdatePerson", "Account")
            .Destroy("_DestroyPerson", "Account")
        .ToolBar(command => command.Create())
        .Columns(col =>
            col.Bound(p => p.PersonId).Hidden();
            col.Bound(p => p.Phone);
            col.Command(command =>
        .Editable(e => e.Mode(GridEditMode.PopUp))

    On edit record in popup editor, have javascript error "SyntaxError: invalid quantifier" because in html field render parameter data-val-regex-pattern="+?d[ds-]+d". All backslashes is disappear. 
    ОК, write expression as @"\\+?\\d[\\d-]+\\d". Validation on page is OK, but in action method ModelState.IsValid = false. How can I solve this problem? Code of action method see below.

    public ActionResult _UpdatePerson([DataSourceRequest] DataSourceRequest request, PersonModel model)
        if (model != null && ModelState.IsValid)
        return new JsonNetResult { Data = ModelState.ToDataSourceResult() };

    Hello Sergey,

    Indeed this is known limitation in current Grid implementation. It will be addressed with next official release.
