Kendo Grid中的寻呼机错误（Nan-Nan of 1 items） [英] Pager error in Kendo Grid(Nan-Nan of 1 items)

问题描述

我正在尝试创建一个包含学生详细信息列表的Kendo网格。点击添加按钮，寻呼机显示Nan-Nan of 1 items。

I am trying to create a Kendo grid with a list of student details. On click of the add button, the pager shows "Nan-Nan of 1 items".

@(Html.Kendo().Grid<Student.Models.StudentDetails>()
            .Name("StudentDetailsGrid")
             .Pageable()
                 .HtmlAttributes(new { id="StudentDetailsGrid"})
            .Columns(col =>
                {col.Bound(a => a.FirstName).Title("Name");

                    col.Bound(a => a.LastName).Hidden()
                    col.Bound(a => a.StudentID).Hidden();
                    col.Command(a => { a.Destroy(); a.Edit(); }).Title("");
                }
            )
            .ToolBar(toolbar => toolbar.Create().Text("Add").HtmlAttributes(new {@id="btnCreateStudent"}))
            .Editable(editable => editable.Mode(GridEditMode.InLine))
                .Scrollable(scrol => scrol.Enabled(true))

            .DataSource(source => source
                .Ajax()
                .PageSize(5)

                .Model(a =>
                {
                    a.Id(b => b.StudentID);


                })

             .Read(read => read.Action()
             .Create(create => create.Action())
             .Destroy(destroy => destroy.Action())
             .Update(update => update.Action())


           ).Events(even => even.Save("SaveDetails").Edit("ChangeNoOfStudent").DataBound("StudentValidate")))

$ b $在Document.ready函数上的b

`

`

：

$(document).ready(function () {
        $.ajax({
                url: '../Student/GetStudentDetails?StudentId=' + Data.StudentId,
                type: 'POST',
                contentType: 'application/json',
                dataType: 'json',
                success: function (data) {

                    if (data.length > 0) {


                        var studentdetail = new kendo.data.DataSource({
                            data: data,
                            pageSize: 5

                        });
                        $("#StudentDetailsGrid").data("kendoGrid").setDataSource(studentdetail);

                    }

我添加了页面大小，但我仍然可以看到Nan-Nan of 1 items。

I have added the page size, but I can still see the "Nan-Nan of 1 items".

你能帮忙吗？

推荐答案

您需要在网格数据源中定义pageSize。不在成功函数中。

You need to define the pageSize in the grid data source. Not in the success function.

在您的情况下，您只需要在数据源中包含以下内容：

In your case you only need to include in your data source the following:

 $.ajax({
                url: '../Student/GetStudentDetails?StudentId=' + Data.StudentId,
                type: 'POST',
                contentType: 'application/json',
                dataType: 'json',
                pageSize: 10,
                success: function (data) {...

我希望这会有所帮助。
