  • WebGrid 在asp.net mvc中的使用和理解(译)

    1:思路

    webgrid就是表格,一行行记录,代表一个个模型,因此,我们只需要在models文件夹建立模型,在控制器生成模型列表,把列表作为模型传入视图(或者绑定强类型视图,这个类型至少大于等于此模型列表),然后通过GetHtml(Model,propetiesList)即可. 非常简单.

    下面对webgrid的一些属性和方法进行介绍(这在设置表格的行列字段属性分页排序等特别适用)

    AjaxUpdateCallback:异步操作完成后的回调函数

    AjaxUpdateContainerId:更新所包括的元素

    CanSort:是否支持排序

    ColumnNames:列的名称列表,类似数据库字段列表,通常我们使用List<string>类型

    HasSelection:判定行的选中

    IsAjaxEnabled Returns a value that indicates whether the WebGrid instance can use Ajax calls to refresh the display

    类似还有行数,默认选中,分页,每页多少行等等属性,具体参考msdn即可.

     请参考原文,感谢作者.

    通过和原文比较,我觉得我的做法也许更好(原文使用的是弱类型视图,然后在视图中去new 模型或模型列表对象)

    我是使用强类型视图,action可以直接传过来,viewbag也可以传过来,视图中也可以new

    cshtml文件如下:

    @{     Layout = null; }

    <!DOCTYPE html>

    <html> <head>     <title>WebgridSample</title>     <script src="../../Scripts/jquery-1.7.1.min.js" type="text/javascript"></script>     <style type="text/css">         .webGrid { margin: 4px; border-collapse: collapse; 500px;  background-color:#FCFCFC;}         .header { background-color: #C1D4E6; font-weight: bold; color: #FFF; }         .webGrid th, .webGrid td { border: 1px solid #C0C0C0; padding: 5px; }         .alt { background-color: #E4E9F5; color: #000; }         .gridHead a:hover {text-decoration:underline;}         .description { auto}         .select{background-color: #389DF5}     </style> </head> <body> @{     WebGridSampleApplication.Models.Product product = new WebGridSampleApplication.Models.Product(); }

     @{
        var grid = new WebGrid(Model, canPage: true, rowsPerPage: 5, selectionFieldName: "selectedRow",ajaxUpdateContainerId: "gridContent");
            grid.Pager(WebGridPagerModes.NextPrevious);}
            <div id="gridContent">
            @grid.GetHtml(tableStyle: "webGrid",
                    headerStyle: "header",
                    alternatingRowStyle: "alt",
                    selectedRowStyle: "select",
                    columns: grid.Columns(
                    grid.Column("Id", format: (i) => i.GetSelectLink(i.Id)),
                             grid.Column("Name", " Name", (i) => i.GetSelectLink(i.Name)),
                    grid.Column("Description", "Description", style: "description"),
                    grid.Column("Quantity", "Quantity")
                      ))

     @if (grid.HasSelection)          {              product = (WebGridSampleApplication.Models.Product)grid.Rows[grid.SelectedIndex].Value;              <b>Id</b> @product.Id<br />              <b>Name</b>  @product.Name<br />              <b>Description</b> @product.Description<br />              <b>Quantity</b> @product.Quantity<br />          }     </div>     </body> </html>

    模型文件如下:

    using System; using System.Collections.Generic; using System.Linq; using System.Web;

    namespace WebGridSampleApplication.Models {     public class Product     {         public string Id { get; set; }         public string Name { get; set; }         public string Description { get; set; }         public long Quantity { get; set; }     } }

    控制器文件如下:

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.Mvc;
    using System.Collections.ObjectModel;
    using WebGridSampleApplication.Models;

    namespace WebGridSampleApplication.Controllers {     public class InventoryController : Controller     {         public ActionResult WebgridSample()         {

                ObservableCollection<Product> inventoryList = new ObservableCollection<Product>();             inventoryList.Add(new Product { Id = "P101", Name = "Computer", Description = "All type of computers", Quantity = 800 });             inventoryList.Add(new Product { Id = "P102", Name = "Laptop", Description = "All models of Laptops", Quantity = 500 });             inventoryList.Add(new Product { Id = "P103", Name = "Camera", Description = "Hd  cameras", Quantity = 300 });

     inventoryList.Add(new Product { Id = "P104", Name = "Mobile", Description = "All Smartphones", Quantity = 450 });
                inventoryList.Add(new Product { Id = "P105", Name = "Notepad", Description = "All branded of notepads", Quantity = 670 });
                inventoryList.Add(new Product { Id = "P106", Name = "Harddisk", Description = "All type of Harddisk", Quantity = 1200 });
                inventoryList.Add(new Product { Id = "P107", Name = "PenDrive", Description = "All type of Pendrive", Quantity = 370 });
                return View(inventoryList);
            }
        }
    }

    hope this would help you
