如何在asp.net mvc中创建分页
本文关键字：创建 分页 mvc net asp | 更新日期: 2024-10-19 10:02:01
我想使用asp.net MVC进行每页5篇文章的分页，我应该添加什么代码？
这里是我的控制器：
using CBA.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using CBA.ViewModels;
using System.Data;
namespace CBA.Controllers
{
public class EventController : Controller
{
private ModelEntities db = new ModelEntities();
public ActionResult Index()
//public ActionResult Index(int page = 1, int pageSize 5)
{
EventDetailsViewModel eventDetail = new EventDetailsViewModel();
MasterEvents events = new MasterEvents();
eventDetail.Title = events.Title;
eventDetail.CreatedTime = events.CreatedTime;
eventDetail.Detail = events.DetailEvent;
eventDetail.CreatedBy = events.CreatedBy_Id;
eventDetail.Description = events.ShortDescription;
CBA.GetContent.GetContentSoapClient service = new CBA.GetContent.GetContentSoapClient();
string[] Content = service.GetContentText("Events", DateTime.Now.ToString("MM-dd-yyyy"), clsEncrypt.EncodeTo64(DateTime.Now.ToString("MM-dd-yyyy")));
if (Content[0] != null)
{
string id = Content[0];
string ContentText;
if (Content[1].Length == 0 && Content[2].Length == 0 && Content[3].Length == 0)
{
ContentText = "";
}
else
{
ContentText = "<div class='"container'" #MARGIN-TOP# ><div class='"row'"><div class='"col-lg-10 col-lg-offset-1'">";
ContentText += "<div class='"col-lg-12'" style='"text-align:center;'"><h1>" + Content[1] + "</h1></div>";
ContentText += "<div class='"col-lg-12'" style='"text-align:center;'"><h2>" + Content[2] + "</h2></div>";
ContentText += "<div class='"col-lg-12'"><div class='"form-group'">" + HttpUtility.HtmlDecode(Content[3]).Replace("src='"/", "src='"" + System.Configuration.ConfigurationManager.AppSettings["replaceURLImageSlider"] + "/") + "</div>";
ContentText += "</div></div></div>";
}
DataTable dtSlider = service.GetContentImageSlider(int.Parse(id), DateTime.Now.ToString("MM-dd-yyyy"), clsEncrypt.EncodeTo64(DateTime.Now.ToString("MM-dd-yyyy")));
if (dtSlider.Rows.Count > 0)
{
string ContentSlider = "<div id='"myCarousel'" class='"carousel slide'"><ol class='"carousel-indicators'">";
for (int i = 0; i < dtSlider.Rows.Count; i++)
{
if (i == 0)
{
ContentSlider += "<li data-target='"#myCarousel'" data-slide-to='"" + i.ToString() + "'" class='"active'"></li>";
}
else
{
ContentSlider += "<li data-target='"#myCarousel'" data-slide-to='"" + i.ToString() + "'"></li>";
}
}
ContentSlider += "</ol><div class='"carousel-inner'">";
for (int i = 0; i < dtSlider.Rows.Count; i++)
{
//dt.Columns.Add("ImageFile", typeof(string));
//dt.Columns.Add("HeaderText", typeof(string));
//dt.Columns.Add("ContentText", typeof(string));
string img = dtSlider.Rows[i]["ImageFile"].ToString().Replace("..", System.Configuration.ConfigurationManager.AppSettings["replaceURLImageSlider"]);
if (i == 0)
{
ContentSlider +=
"<div class='"item active'" style='"background:url('" + dtSlider.Rows[i]["ImageFile"].ToString().Replace("..", System.Configuration.ConfigurationManager.AppSettings["replaceURLImageSlider"]) + "') "
+ "no-repeat center center; -webkit-background-size: cover; -moz-background-size: cover; "
+ "-o-background-size: cover;background-size: cover;'">"
+ "<div class='"container'">"
+ "<div class='"carousel-caption'">"
+ "<div class='"col-lg-6'" style='width:260px;'>"
+ "<h1>" + (string)dtSlider.Rows[i]["HeaderText"] + "</h1>"
+ "<p class='"scroll_bni'" style='width: 260px;'>"
+ (string)dtSlider.Rows[i]["ContentText"]
+ "</p>"
+ "</div>"
+ "</div>"
+ "</div>"
+ "</div>";
}
else
{
ContentSlider +=
"<div class='"item'" style='"background:url('" + dtSlider.Rows[i]["ImageFile"].ToString().Replace("..", System.Configuration.ConfigurationManager.AppSettings["replaceURLImageSlider"]) + "') "
+ "no-repeat center center; -webkit-background-size: cover; -moz-background-size: cover; "
+ "-o-background-size: cover;background-size: cover;'">"
+ "<div class='"container'">"
+ "<div class='"carousel-caption'">"
+ "<div class='"col-lg-6'" style='width:260px;'>"
+ "<h1>" + (string)dtSlider.Rows[i]["HeaderText"] + "</h1>"
+ "<p class='"scroll_bni'" style='width: 260px;'>"
+ (string)dtSlider.Rows[i]["ContentText"]
+ "</p>"
+ "</div>"
+ "</div>"
+ "</div>"
+ "</div>";
}
}
ContentSlider += "</div><a class='"left carousel-control'" href='"#myCarousel'" data-slide='"prev'"><span class='"glyphicon glyphicon-chevron-left'"></span></a><a class='"right carousel-control'" href='"#myCarousel'" data-slide='"next'"><span class='"glyphicon glyphicon-chevron-right'"></span></a></div>";
ViewBag.Carousel = ContentSlider;
}
else
{
ContentText = ContentText.Replace("#MARGIN-TOP#", "style='"margin-top:60px;'"");
}
ContentText = ContentText.Replace("#MARGIN-TOP#", "");
ViewBag.Content = ContentText;
}
return View(db.MasterEvents.ToList());
}
public ActionResult ViewEvents(int id)
{
MasterEvents MasterEvents = db.MasterEvents.Find(id);
ViewBag.data = id;
return View();
}
}
}
我的观点是：
@model IEnumerable<CBA.Models.MasterEvents>
@{
ViewBag.Title = "Recruitment - DDR Events";
ViewBag.lnkEvents = "active";
Layout = "~/Views/Shared/ContentFrontEnd.cshtml";
}
<!-- Carousel
================================================== -->
@Html.Raw(ViewBag.Carousel)
<!-- /.carousel -->
<!-- Content
================================================== -->
@Html.Raw(ViewBag.Content)
<!-- /.Content -->
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
</head>
<body>
<div class="container" style="background-color: white; border-radius: 0 0 15px 15px; margin-bottom: 40px;">
<div class="row" style="margin-top: 30px;">
<div class="col-lg-10 col-lg-offset-1">
@foreach (var item in Model)
{
<div class="blog-post">
<h2 class="blog-post-title">@Html.DisplayFor(modelItem => item.Title)</h2>
<p class="blog-post-meta">
Created Time @Html.DisplayFor(modelItem => item.CreatedTime)
<!--by <a href="#">@Html.DisplayFor(modelItem => item.CreatedBy_Id)</a></p>-->
<h2 class="blog-post-title">@Html.DisplayFor(modelItem => item.ShortDescription)</h2>
<div class="readmore">
<p>
@{
string parameterValue = "";
if (item.DetailEvent.ToString().Length < 100)
{
parameterValue = item.DetailEvent;
}
else
{
parameterValue = item.DetailEvent.ToString().Substring(0, 200);
}
}
@Html.Raw(parameterValue);
</p>
</div>
<br />
@Html.ActionLink("Read More..", "ViewEvents", "Event", new { id = 7 }, new { @class = "btn btn-primary btn-lg", style = "width:180px;" })
</p>
<p class="blog-post-meta">
Update Time @Html.DisplayFor(modelItem => item.UpdatedTime)
<p>
</div>
}
<nav>
<ul class="pager">
<li><a href="#">Previous</a></li>
<li><a href="#">Next</a></li>
</ul>
</nav>
</div>
</div>
</div>
</body>
</html>
这里是我的模型：
using System;
using System.Collections.Generic;
using System.Linq;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Web;
namespace CBA.Models
{
public class MasterEvents
{
[Key]
[DisplayName("ID")]
[ScaffoldColumn(false)]
public int Id { get; set; }
[Required(ErrorMessage = "Required Events Title")]
[DisplayName("Title")]
[StringLength(250)]
public string Title { get; set; }
[Required(ErrorMessage = "Required Short Description")]
[DisplayName("Short Description")]
[StringLength(250)]
public string ShortDescription { get; set; }
[Required(ErrorMessage = "Required Details")]
[DisplayName("Detail Events")]
[StringLength(20)]
public string DetailEvent { get; set; }
[DisplayName("Created Time")]
public System.DateTime? CreatedTime { get; set; }
[DisplayName("Updated Time")]
public System.DateTime? UpdatedTime { get; set; }
[DisplayName("Created By")]
public int? CreatedBy_Id { get; set; }
[DisplayName("Updated By")]
public int? UpdatedBy_Id { get; set; }
}
}
如何进行分页，我想每页5篇文章进行分页。。
任何系统中的分页通常包括在控制器方法中获取page number和count per page，这样您就可以将这些值传递给业务层或数据访问层中的search方法，以仅获取所需的内容。
所以本质上：
修改Index控制器方法如下：Index(int page = 1, int countPerPage = 5)
这将允许您在控制器中传递page number和count per page，然后您可以使用它们传递给搜索方法。
您还需要创建一个显示页码的UI。计算需要显示的页面数量的一种方法是返回搜索中存在的TOTAL项目数（根据搜索方法），然后将其除以countPerPage值。
我希望这能把你推向正确的方向。
