mvcpager之学习

一、项目中必须引用MVCpager.dll，现在是3.0版本。

二、添加页面view.Model

namespace Model.ViewModel
{
    public class VolumeTree
    {
        public int VolumeID { get; set; }
        public string VolumeName{ get; set; }
        public List<Subsection> SubsectionS { get; set; }

    }
    public class Subsection
    {
        public int SubsectionID { get; set; }
        public string SubsectionName { get; set; }

        public string PoetryName { get; set; }

    }
    public class Poet {
        public int PoetID { get; set; }
        public string powtName { get; set; }
    }
    public class Poetry
    {
        public int PoetryID { get; set; }
        public string PoetryName { get; set; }
        public Poet poet { get; set; }

    }
}

View Model

三、控制器代码，也是默认页面index

 public ActionResult index(int? id = 1)
        {
            // List<Model.ViewModel.VolumeTree> VolunePage = new List<Model.ViewModel.VolumeTree>();
            // int totalCount = 0; /*OperateContext.Current.BLLSession.IVolumeBLL.GetListBy_NoTrack(s => s.VolumeID > 0).ToList().Count();*/
            int pageIndex = id ?? 1;
            // var VolunePage = OperateContext.Current.BLLSession.IVolumeBLL.getPageDate(pageIndex, 2,s=>s.VolumeID>0,s=>s.VolumeID, out totalCount,true);
            var VolunePage = OperateContext.Current.BLLSession.IVolumeBLL.GetListBy_NoTrack(s => s.VolumeID > 0).Select(s => new Model.ViewModel.VolumeTree
            {
                VolumeID = s.VolumeID,
                VolumeName = s.VolumeName,
                SubsectionS = s.Subsection.Select(u => new Model.ViewModel.Subsection
                {
                    SubsectionID = u.SubsectionID,
                    SubsectionName = u.SubsectionName,
                    PoetryName = u.Poetries.Select(p => p.PoetryName).FirstOrDefault()

                }).ToList()
            }).ToList();
            PagedList<Model.ViewModel.VolumeTree> mPage = new PagedList<Model.ViewModel.VolumeTree>(VolunePage, pageIndex, 5);
            //mPage.TotalItemCount = totalCount;
            //mPage.CurrentPageIndex = (int)(id ?? 1);

            if (Request.IsAjaxRequest())
            {
                return PartialView("VolumeTreeMvcPager", mPage);
            }
            return View(mPage);

控制器代码

四、index页面cshtml，这是第一视图，获取model,同时传给VolumeMvcpagerTree.cshtml

@model PagedList<Model.ViewModel.VolumeTree>
@using Webdiyer.WebControls.Mvc;
@{
    ViewBag.Title = "index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<div>
    <h2>管理</h2>

    <div id="MVCpager">
        @Html.Partial("VolumeMvcpagerTree", Model)
    </div>
</div>

index页面

五、局部视图，将主页index的Model解析，绑定数据，用户呈现，主要是要把Mvcpager的分页html.help搞定

@model PagedList<Model.ViewModel.VolumeTree>
@using Webdiyer.WebControls.Mvc;

<ul>

    @if (Model != null)
    {
        foreach (var item in Model)
        {
            <li>
                @item.VolumeName<span>‘<a href="javascript:;">增加分卷</a></span>
                <ul>
                    @if (item != null)
                    {
                        foreach (var Sub in item.SubsectionS)
                        {
                            <li>@Sub.SubsectionName</li> }

                    }
                </ul>
            </li>
        }
    }

</ul>

@if (Model != null)
{
    <div class="text-center">
        @Ajax.Pager(Model, new PagerOptions
   {
       PageIndexParameterName = "id",
       FirstPageText = "首页",
       PrevPageText = "上一页",
       NextPageText = "下一页",
       LastPageText = "末页",
       NumericPagerItemCount = 5,
       ContainerTagName = "ul",
       CssClass = "pagination",
       CurrentPagerItemTemplate = "<li class=\"active\"><a href=\"#\">{0}</a></li>",
       DisabledPagerItemTemplate = "<li class=\"disabled\"><a>{0}</a></li>",
       PagerItemTemplate = "<li>{0}</li>"
   }).AjaxOptions(a => a.SetUpdateTargetId("MVCpager"))
    </div>
}
