即使记录在那里，Kendo Pager（可分页）也显示“没有要显示的项目”

Question

我在这里使用带有 Angular-JS 的 Kendo-UI。

在剑道网格表上集成分页（可分页）时遇到问题，即使数据（记录）正确加载，它也会显示“没有要显示的项目”。

不知道有什么问题，任何帮助都会被占用......

以下是我用来加载/初始化数据网格的函数。

function getProjectsAtAGlance() {
                $scope.gridOptions = {
                    scrollable: false,
                    sortable: true,
                    pageable: {
                        pageSizes: [5, 10, 15, 20, 25, 50]
                    },
                    change: function (e) {
                        $scope.pageSize = $scope.gridOptions.dataSource.pageSize();
                    },
                    dataSource: {
                        serverPaging: true,
                        transport: {
                            read: function (options) {

                                $scope.options = options;

                                var filters = {
                                    skip: options.data.skip,
                                    take: options.data.take,
                                    sortBy: $scope.sortBy,
                                    projectGlanceIncludeArchived: $scope.includeArchivedProjects,
                                    projectGlanceExcludeProjectsWithNoBudgets: $scope.excludeProjectsWithNoBudgets
                                };

                                $http.post("/Home/ProjectsAtAGlanceReport", filters)
                                    .success(function (result) {
                                        var projects = result.projects;

                                        for (var i = 0; i < projects.length; i++) {
                                            var project = projects[i];
                                            project.startDate = moment(projects[i].startDate).format("L");
                                            project.endDate = moment(projects[i].endDate).format("L");
                                        }

                                        options.success(projects);

                                    })
                                    .error(function (error) {
                                        console.log(error);
                                    });
                            }
                        },

Answer 1

我认为pageSize 属性需要在dataSource 中声明，如下所示：

dataSource: {
    serverPaging: true,
    transport: {... // transport options
    },
    pageSize: $scope.pageSize // before end of dataSource       
},... // more grid stuff

根据documentation，将您返回的内容从schema.total 更改为return response.total。
