我目前正在研究一个存在分页问题的网格。网格填充到其中包含 15 个项目。这是最大页面大小，但是，超出此范围不会添加页面。我不完全确定为什么它不添加页面。下面是我的代码。

看法

var gridPageSize = EngineContext.Current.Resolve<Nop.Core.Domain.Common.AdminAreaSettings>().GridPageSize;
    <table class="adminContent">
        <tr>
            <td>
                @(Html.Telerik().Grid<CategoryModel.CategoryUnitsModel>()
                    .Name("categoryunits-grid")
                    .DataKeys(keys =>
                    {
                        keys.Add(x => x.Id);
                        keys.Add(x => x.CategoryId);
                        keys.Add(x => x.UnitId);
                    })
                    .DataBinding(dataBinding =>
                    {
                        dataBinding.Ajax()
                            .Select("CategoryUnitsList", "Category", new { categoryId = Model.Id })
                            .Insert("CategoryUnitsInsert", "Category", new { categoryId = Model.Id })
                            .Update("CategoryUnitsInsert", "Category", new { categoryId = Model.Id })
                            .Delete("CategoryUnitsDelete", "Category", new { categoryId = Model.Id });
                    })
                    .Columns(columns =>
                    {
                        columns.Bound(x => x.UnitId)
                            .Visible(false);
                        columns.Bound(x => x.UnitText);
                        columns.Command(commands =>
                        {
                            commands.Edit();
                            commands.Delete();
                        })
                        .Width(100);
                    })
                    .ToolBar(commands => commands.Insert())
                    .Pageable(settings => settings.PageSize(gridPageSize).Position(GridPagerPosition.Both))
                    .ClientEvents(events => events.OnRowDataBound("onRowDataBound"))
                    .ClientEvents(events => events.OnEdit("onEdit"))
                    .EnableCustomBinding(true))

                <script type="text/javascript">
                    function onRowDataBound(e) {
                        $(e.row).find('a.t-grid-edit').remove(); //remove Delete button
                    }

                    function onEdit(e) {
                        $.getJSON('@Url.Action("LoadAvailableUnits", "Category")', { categoryId: $("#Id").val() }, function (data) {
                            var ddl = $("#UnitText").data("tDropDownList");
                            if (data.length > 0) {
                                ddl.dataBind(data);
                                ddl.reload();
                            }
                            else {
                                $('a[class="t-button t-grid-cancel"]').click();
                                alert("There are no Units left to select from");
                            }
                        });
                    }
                </script>
            </td>
        </tr>
    </table>

EditorTemplates\CategoryUnit

@using Telerik.Web.Mvc.UI;
@Html.Telerik().DropDownList().Name("UnitText")

模型（CategoryModel.CategoryUnitsModel）

public partial class CategoryUnitsModel : BaseNopEntityModel
    {
        public int CategoryId { get; set; }
        public int UnitId { get; set; }
        [NopResourceDisplayName("Admin.Catalog.Categories.Units.Fields.UnitText")]
        [UIHint("CategoryUnit")]
        public string UnitText { get; set; }
    }

控制器

[HttpPost, GridAction(EnableCustomBinding = true)]
    public ActionResult CategoryUnitsList(GridCommand command, int categoryId)
    {
        if (!_permissionService.Authorize(StandardPermissionProvider.ManageCatalog))
            return AccessDeniedView();

        var categoryUnits = _unitsService.GetCategoryUnits(categoryId, command.Page - 1, command.PageSize);
        var categoryUnitsModel = PrepareCategoryUnitsModel(categoryUnits);

        var model = new GridModel<CategoryModel.CategoryUnitsModel>
        {
            Data = categoryUnitsModel,
            Total = categoryUnitsModel.Count
        };

        return new JsonResult
        {
            Data = model
        };
    }

    public JsonResult LoadAvailableUnits(int categoryId)
    {
        var categoryUnits = _unitsService.GetAvailableUnits(categoryId);
        var categoryUnitsModel = PrepareAvailableUnitsInModel(categoryUnits);
        var returnData = new SelectList(categoryUnitsModel, "UnitId", "UnitText");
        return Json(returnData, JsonRequestBehavior.AllowGet);
    }

    [GridAction(EnableCustomBinding = true)]
    public ActionResult CategoryUnitsInsert(GridCommand command, CategoryModel.CategoryUnitsModel model)
    {
        if (!_permissionService.Authorize(StandardPermissionProvider.ManageCatalog))
            return AccessDeniedView();

        var searchForEntry = _unitsService.GetCategoryUnitByCategoryIdAndUnitId(model.CategoryId, Int32.Parse(model.UnitText));
        if (searchForEntry != null)
        {
            return CategoryUnitsList(command, model.CategoryId);
        }

        var categoryUnit = new CategoryUnits
        {
            UnitId = Int32.Parse(model.UnitText),
            CategoryId = model.CategoryId
        };

        _unitsService.InsertCategoryUnit(categoryUnit);

        return CategoryUnitsList(command, model.CategoryId);
    }

    [GridAction(EnableCustomBinding = true)]
    public ActionResult CategoryUnitsDelete(GridCommand command, CategoryModel.CategoryUnitsModel model, int id)
    {
        if (!_permissionService.Authorize(StandardPermissionProvider.ManageCatalog))
            return AccessDeniedView();

        var categoryId = model.CategoryId;
        _unitsService.DeleteCategoryUnit(model.CategoryId, id);

        return CategoryUnitsList(command, categoryId);
    }

任何帮助将非常感激。谢谢大家。

最诚挚的问候，查德·约翰逊

没关系，我想通了这个问题。在我的控制器中，当我在绑定网格时设置总计时，我使用的是已绑定到模型的数据计数，而不是我的实体带回的总计数。
