viewmodel زیر رو ایجاد کردم:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace QA_Software.ViewModel
{
    public class CreateRevisionRequestViewModel
    {
        public Models.RevisionDocUnit RevisionDocUnit { get; set; }

        public List<Models.RevisionDocUnit> RevisionDocUnits { get; set; }

        public Models.Document Document { get; set; }

        public List<Models.Document> Documents { get; set; }

    }
}

view زیر رو ایجاد و ویو مدل رو در اون استفاده کردم

@model QA_Software.ViewModel.CreateRevisionRequestViewModel
@using GridMvc.Html

@{
    ViewBag.Title = "CreateRevisionRequest";
    Layout = "~/Views/Shared/_MyLayoutPage.cshtml";
    <link href="~/Content/bootstrap.min.css" rel="stylesheet" />
    <link href="~/Content/PersianDatePicker.css" rel="stylesheet" />
}
<style type="text/css">
    .MyPage {
        text-align: right;
        direction: rtl;
    }
</style>
