MVC进阶学习HtmlHelper之GridView控件拓展(二)

1.目录结构图
      





2.自定义集合类

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

namespace MvcTest.Code
{
    public class PageList<T> : List<T>
    {
        private CommonPage _page;

        public CommonPage Page
        {
            get { return _page; }
            set { _page = value; }
        }

        private string _sort;

        public string Sort1
        {
            get { return _sort; }
            set { _sort = value; }
        }

        private string _identityName;

        public string IdentityName
        {
            get { return _identityName; }
            set { _identityName = value; }
        }

        private string _controller;

        public string Controller
        {
            get { return _controller; }
            set { _controller = value; }
        }

        private string _action;

        public string Action
        {
            get { return _action; }
            set { _action = value; }
        }

        public PageList(IEnumerable<T> items, 
            CommonPage page, 
            string sort, 
            string identityName, 
            string controller, 
            string action)
        {
            this.AddRange(items);
            this.Page = page;
            this._sort = sort;
            this._identityName = identityName;
            this._controller = controller;
            this._action = action;
        }
    }
}

      自定义集合PageList,主要作为扩展的GridView 的数据源，这种扩展的就是为了引入分页对象，排序规则，表格的主键名称，分页所提交的控制器（Controller）和Action。在分页的过程中，Controller和Action处理这个GridView 传递过来的分页请求。定义主键名称则是为了在删除和编辑的时候更好的确定对象。PageList<T>:List<T> 扩展自泛型，就是为了能够能够兼容各种数据模型

3.分页对象

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

namespace MvcTest.Code
{
    [Serializable]
    public class CommonPage
    {
        public CommonPage()
        { 
        }

        private int _pageSize;

        public int PageSize
        {
            get { return _pageSize; }
            set { _pageSize = value; }
        }

        private int _total;

        public int Total
        {
            get { return _total; }
            set { _total = value; }
        }

        private int _pageIndex;

        public int PageIndex
        {
            get { return _pageIndex; }
            set { _pageIndex = value; }
        }

        private int _pageCount;

        public int PageCount
        {
            get { return _pageCount; }
            set { _pageCount = value; }
        }
    }
}

 这个对象只是为了封装分页的时候一些数据信息:Total 总数据行数, PageSize每页数据行数, PageIndex 页面是第几页, PageCount  总页数. 这个类其实是为PageList<T> 这个类服务的，我们也可以将这些属性封装到PageList<T>当中去，只不过PageList<T> 中的参数过多，显示有些不美观

4.编辑删除对象对象

103     }
104 }
105 

            _isEidt = isEdit;          表示是否显示编辑
            _editButton = editButton; 编辑按钮显示字样
            _isDelete = isDelete;   表示是否显示删除
            _deleteButton = deleteButton; 删除按钮显示字样
            _headers = heander;       这个是数组类型，表示显示标题的字样
            _deleteController = deleteController;  删除的时候由哪个控制器处理
            _deleteAction = deleteAction;           删除的时候由哪个控制器中的action处理
            _editController = editController;       编辑的时候由哪个控制器处理
            _editAction = editAction;                编辑的时候由哪个控制器中的action处理
           如果IsEdit,IsDelete的值设置为false 的话，即使对应的编辑按钮设置了值也不能显示，以后的Controller 和Action必须指定，否则编辑或删除的时候就没有指定处理的控制器，就不能处理这些请求
