从KendoUI网格模型绑定排序字段 [英] Model binding the sort field from KendoUI Grid

问题描述

我用KendoUI网显示的数据。我有服务器的分页像一个魅力的工作。在剑道网格中每个页面的变化是一个新的AJAX请求到服务器和服务器返回的数据的正确的页面。我现在试图做服务器端的排序，但我遇到了麻烦模型绑定绑定到排序值。

I'm using KendoUI Grid to show data. I have server paging working like a charm. The each page change in the kendo grid is a new ajax request to the server and the server returns the correct page of data. I am now trying to do server-side sorting, but I'm having trouble getting model binding to bind to the sort values.

这是从剑道电网的要求是这样的：

This is what the request from the Kendo Grid looks like:

我的操作方法是这样的：

My action method looks like this:

public JsonResult GetReports(int pageSize, int skip, List<KendoSort> sort)
{
    // sort is not being populated with the right data.
}

KendoSort是一个自定义类：

KendoSort is a custom class:

public class KendoSort
{
    public string Field { get; set; }
    public string Dir { get; set; }
}

我知道我不是这样做的权利。如何使我的操作方法寻找正确捕捉排序提供的数据？截屏显示在排序集合只有一个项目，但电网可以传递更多。例如，它也可以包含一个额外的排序：

I know I'm not doing this right. How should my action method look to correctly capture the data supplied for the sort? The screenshot shows only a single item in the sort collection, but the grid could pass more. For example, it could also have included an additional sort:

sort[1][field]: reportName
sort[1][dir]: asc

基本上，它会说排序编号升序排列，然后所以reportName升序排列。我怎样才能得到这些数据转化为我的行为方式，而不必闲逛在要求和手动解析参数？

推荐答案

在ASP.NET MVC模型绑定不明白EX pressions像排序[0] [现场] 。据了解仅排序[0]点域这是不幸的，因为 jQuery.ajax 提交前格式嵌套的对象。

The ASP.NET MVC model binder does not understand expressions like sort[0][field]. It understands only sort[0].field which is unfortunate because jQuery.ajax submits nested objects in the former format.

有两种方法来解决这个问题：

There are two ways to solve the problem:

1. 使用剑道UI完整的ASP.NET MVC。它配备了一个内置的模式，为电网的要求。更多信息可以发现<一href="http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/ajax-binding">here.

2. 创建一个<一个href="http://docs.kendoui.com/api/framework/datasource#transportparametermap-function">parameterMap并翻译排序前pression：

1. Use Kendo UI Complete for ASP.NET MVC. It comes with a built-in model for the grid request. More info can be found here.

2. Create a parameterMap and translate the sort expression:

parameterMap: function(options) {
     var result = {
       pageSize: options.pageSize,
       skip: options.skip
     };

     if (options.sort) {
         for (var i = 0; i < options.sort.length; i++) {
            result["sort[" + i + "].field"] = options.sort[i].field;
            result["sort[" + i + "].dir"] = options.sort[i].dir;
         }
     }

     return result;
}

我没有最终使用参数映射，而不是重新结构中的排序字段我只是字符串化的选项，指定的contentType的CRUD传输。该模型粘合剂知道要绑定到字符串化的JSON只要指定了的contentType。

UPDATE FROM QUESTION AUTHOR:

I did end up using parameter map, but rather than re-structure the sort field I simply stringified the options and specified the contentType on the CRUD transports. The model binder knows to bind to the stringified JSON as long as the contentType is specified.

transport: {
    read: {
        url: '...',
        type: 'POST',
        contentType: 'application/json'
    },
    update: {
        url: '...',
        type: 'POST',
        contentType: 'application/json'
    },
    destroy: {
        url: '...',
        type: 'POST',
        contentType: 'application/json'
    },
    create: {
        url: '...',
        type: 'POST',
        contentType: 'application/json'
    },
    parameterMap: function (options, type) {
        return JSON.stringify(options);
    }
}
