02.Ext创建一个数据表格

2018-06-22 06:15:50来源：未知阅读 ()

做惯了后台的沐雨一向觉得数据列表是一个系统里面最重要的东西所以熟悉ext也就从表格开始入手了

想看官方代码的同学进这里官方默认表格教程或是直接看我的也行，直接拷贝过来的另外官方文档没有中文版的让我这个二级都没过的学渣倍感压力啊

1. Views部分代码

官方文档一直没看到下图Layout的代码在哪里所以为了让程序能正常运行直接自己做一个最简单的吧

在Views/Shared文件夹下创建一个名为_BaseLayout的MVC5布局页，代码如下

@Html.X().ResourceManager()
<div style="margin:10px;">
@RenderSection("headtag")
@RenderSection("example")
</div>

现在官网缺失的部分写好了,开始写内容页，沐雨这里是直接把Views/Home/Index.cshtml 给改了，代码如下

@model System.Collections.IEnumerable

@{
    ViewBag.Title = "Simple Array Grid - Ext.NET MVC Examples";
    Layout = "~/Views/Shared/_BaseLayout.cshtml";
}

@section headtag
{
    <style>
        .x-grid-row-over .x-grid-cell-inner {
            font-weight: bold;
        }
    </style>

    <script>
        var template = '<span style="color:{0};">{1}</span>';

        var change = function (value) {
            return Ext.String.format(template, (value > 0) ? "green" : "red", value);
        };

        var pctChange = function (value) {
            return Ext.String.format(template, (value > 0) ? "green" : "red", value + "%");
        };
    </script>
}

@section example
{
    <h1>Simple Array Grid</h1>

    @(Html.X().GridPanel()
        .Title("Array Grid")
        .Width(600)
        .Height(350)
        .Store(Html.X().Store()
            .Model(Html.X().Model()
                .Fields(
                    new ModelField("company"),
                    new ModelField("price", ModelFieldType.Float),
                    new ModelField("change", ModelFieldType.Float),
                    new ModelField("pctChange", ModelFieldType.Float),
                    new ModelField("lastChange", ModelFieldType.Date, "M/d hh:mmtt")
                )
            )
            .DataSource(Model)
        )
        .ColumnModel(
            Html.X().Column().Text("Company").DataIndex("company").Flex(1),
            Html.X().Column().Text("Price").DataIndex("price").Renderer(RendererFormat.UsMoney),
            Html.X().Column().Text("Change").DataIndex("change").Renderer("change"),
            Html.X().Column().Text("Change").DataIndex("pctChange").Renderer("pctChange"),
            Html.X().DateColumn().Text("Last Updated").DataIndex("lastChange")
        )
    )
}

2.Controller部分代码

修改Controller/HomeController代码如下

using MuYu.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MuYu.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View(Companies.GetAllCompanies());
        }
    }
}

3.Models部分代码

Models下添加一个Companies类，代码如下

using System;
using System.Collections;

namespace MuYu.Models
{
    public class Companies
    {
        public static IEnumerable GetAllCompanies()
        {
            return new object[]
                {
                    new object[] { "3m Co", 71.72, 0.02, 0.03, "9/1 12:00am" },
                    new object[] { "Alcoa Inc", 29.01, 0.42, 1.47, "9/1 12:00am" },
