自定义Ajax绑定无法正常工作

Question

我有以下代码用于自定义Ajax绑定。即使它正在显示第一页的数据，也有以下问题。

•request.Sorts作为NULL进入Orders_Read方法

•request.PageSize作为0传递给Orders_Read方法

•request.Page以1的形式出现在Orders_Read方法中（即使我单击第2页）

为了获得正确的排序和页面大小值，需要在此处进行哪些更改？

注意：我正在为Kendo Grid使用MVC包装器。

VIEW

@Scripts.Render("~/bundles/jquery")

<script type ="text/javascript">      
$(document).ready(function ()
    $('#Submit1').click(function () 
        alert('1');
        $('#grid12').data('kendoGrid').dataSource.read();
    );
);  
</script>
@model KendoPratapSampleMVCApp.Models.Sample
@
ViewBag.Title = "CustomAjaxbind";


<h2>CustomAjaxbind</h2>
@using (html.BeginForm("PostValues", "CustomAjaxBinding", FormMethod.Post))
 

<input id="Submit1" type="button" value="SubmitValue" />
@(Html.Kendo().Grid<KendoPratapSampleMVCApp.Models.Sample>()    
.Name("grid12")
.EnableCustomBinding(true)
.Columns(columns => 
    columns.Bound(p => p.SampleDescription).Filterable(false).Width(100);
    columns.Bound(p => p.SampleCode).Filterable(false).Width(100);
    columns.Bound(p => p.SampleItems).Filterable(false).Width(100);
)
.Pageable()
.Sortable()
.Scrollable()
.AutoBind(false)
.Filterable()
.HtmlAttributes(new  style = "height:430px;" )
.DataSource(dataSource => dataSource
    .Ajax()
    .PageSize(2)
    .Read(read => read.Action("Orders_Read", "CustomAjaxBinding"))
 )
)

Controller

public class CustomAjaxBindingController : Controller

    //
    // GET: /CustomAjaxBinding/

    public ActionResult Index()
    
        return View("CustomAjaxbind");
    

    public ActionResult Orders_Read([DataSourceRequest(Prefix = "grid12")]DataSourceRequest request)
    

        string sortField = "SampleDescription";
        string sortDirection = string.Empty;

        if (request.Sorts != null)
        
            foreach (SortDescriptor sortDescriptor in request.Sorts)
            
                sortField = sortDescriptor.Member;
                if (sortDescriptor.SortDirection == ListSortDirection.Ascending)
                
                    sortDirection = "Ascending";
                
                else
                
                    sortDirection = "Descending";
                
            
        

        int total = 1;
        int myPageSize = 2;  
        if(request.PageSize !=0)
        
            myPageSize = request.PageSize;
        

        IEnumerable<Sample> currentSamples = GetSubsetEmployees(request.Page - 1, myPageSize, out total, sortField, sortDirection);

        var result = new DataSourceResult()
        
            Data = currentSamples, 
            Total = total // Total number of records
        ;

        return Json(result);
    

    public IEnumerable<Sample> GetSubsetEmployees(int pageIndex, int pageSize, out int itemCount, string sortField, string sortDirection)
    

        IEnumerable<Sample> samples = GetSamples();
        itemCount = samples.ToList().Count;

        var selector = new Func<Sample, object>(e => e.GetType().GetProperty(sortField).GetValue(e, null));
        var query = sortDirection.Equals("descending", StringComparison.OrdinalIgnoreCase)
                        ? samples.OrderByDescending(selector)
                        : samples.OrderBy(selector);

        List<Sample> currentPageEmployees = query
            .Skip(pageIndex * pageSize)
            .Take(pageSize)
            .ToList();

        return currentPageEmployees;

    

   public static IEnumerable<Sample> GetSamples()
    
        List<Sample> sampleAdd = new List<Sample>();
        Sample s12 = new Sample();
        s12.SampleCode = "1";
        s12.SampleDescription = "A";
        s12.SampleItems = "newone";

        Sample s2 = new Sample();
        s2.SampleCode = "2";
        s2.SampleDescription = "B";
        s2.SampleItems = "oldone";

        Sample s3 = new Sample();
        s3.SampleCode = "3";
        s3.SampleDescription = "C";
        s3.SampleItems = "latestone";

        Sample s4 = new Sample();
        s4.SampleCode = "4";
        s4.SampleDescription = "D";
        s4.SampleItems = "latestoneitem";

        sampleAdd.Add(s12);
        sampleAdd.Add(s2);
        sampleAdd.Add(s3);
        sampleAdd.Add(s4);
        return sampleAdd;
