MVC - 选择全部复选框

Question

我有一个模型，我在视图中实现了。数据传递给控制器​​，我使用控制器中的表单集合检索值。我共有50条记录，每页显示10条记录。问题是，当我试图选中全部选中复选框时，所有50条记录都被选中。但是当我提交时，在控制器中，表单集合只有当前的第10页记录ID。其余的记录没有通过。请帮我找到解决方案或提供问题的替代方案。

       --Controller code
    [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult AssignLibrarian(FormCollection FC, string command)
        {
    foreach (string key in FC.AllKeys)
                {
                    // Process Id Key values
                    if (key == "item.Id")
                    {   
                        string IdValues = FC[key];
                        string[] PartIdArray = IdValues.Split(',');

                        foreach (string str in PartIdArray)
                            PartIdDictionary.Add(i++, str);
                    }
                    if (key == "item.IsSelected")
                    {
                        string SelectedIdValues = FC[key];
                        string[] PartSelectedIdArray = SelectedIdValues.Split(',');

                        for (int PartId = 0; PartId < PartSelectedIdArray.Length; PartId++)
                        {
                            if (PartSelectedIdArray[PartId] == "true")
                            {
                                PartSelectedIdDictionary.Add(j++, PartSelectedIdArray[PartId]);
                                PartId++;
                            }
                            else
                                PartSelectedIdDictionary.Add(j++, PartSelectedIdArray[PartId]);
                        }

                    }
    }
}
