ASP.NET中怎么实现无刷新分页

CREATE procedure [dbo].[P_Pager]  (@PageNumber int,  @PageSize int)  as  declare @sql nvarchar(4000)      set @sql = 'select top ' + Convert(varchar, @PageSize)   + ' * from T_Test where [type]=1 and id not in (select top ' + Convert(varchar, (@PageNumber - 1) * @PageSize)  + ' id from T_Test order by id desc) order by id desc'  exec sp_executesql @sql  GO

                                  
                                                                                       
                                     
                                         <%#Eval("username") %>：<%#Eval("content").ToString())) %>
                                     
                                         发表时间：                                             <%#Eval("addtime") %>                                                                              
                                 
                                                                           
                     
                             总记录：
                         
                                                                                   
                     

3、AspNetPager分页控件

可以看到以上的代码有个分页控件，我相信这个分页控件大家都不陌生了，我就不多介绍。必须有AspNetPager.dll，然后在项目中引用，在头部引入这一段代码：

<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>

这时候分页控件应该就可以使用了。***在后台绑定一下数据，同时也要绑定AspNetPager控件，完整的后台代码如下：

using System;  using System.Collections.Generic;  using System.Web;  using System.Web.UI;  using System.Web.UI.WebControls;  using System.Data;  using Wuqi.Webdiyer;  using System.Data.SqlClient;     public partial class AjaxPager : System.Web.UI.Page  {      int currentPageNumber;//当前页号       int pageSize = 5;//每页显示记录条数      protected void Page_Load(object sender, EventArgs e)      {          if (!IsPostBack)          {              currentPageNumber = 1;              ViewState["currentPageNumber"] = currentPageNumber;              BindData();          }          AspNetPager1.PageChanged += new EventHandler(AspNetPager1_PageChanged);  //定义控件分页事件      }         //获取记录总数      private int GetCount()      {          string sql = "select COUNT(*) from T_Test";          DataTable dt = GetTable(sql, CommandType.Text, values);          if (dt.Rows.Count > 0)          {              return Convert.ToInt32(dt.Rows[0][0]);          }          else         {              return 0;          }      }             //绑定数据      private void BindData()      {          ltlCount.Text = GetCount().ToString();          currentPageNumber = Convert.ToInt32(ViewState["currentPageNumber"]);          SqlParameter[] values = { new SqlParameter("@PageNumber", currentPageNumber), new SqlParameter("@PageSize", pageSize) };                     DataTable dt = GetTable("P_Pager", CommandType.StoredProcedure, values);  //调用存储过程          if (dt.Rows.Count > 0)          {              AspNetPager1.PageSize = pageSize;              AspNetPager1.RecordCount = GetCount();              AspNetPager1.CurrentPageIndex = currentPageNumber;              this.Repeater1.DataSource = dt.DefaultView;              this.Repeater1.DataBind();          }      }         //分页事件       void AspNetPager1_PageChanged(object sender, EventArgs e)      {          currentPageNumber = AspNetPager1.CurrentPageIndex;          ViewState["currentPageNumber"] = currentPageNumber;          BindData();      }              // 读取存储过程返回table      private DataTable GetTable(string sql, CommandType t, params SqlParameter[] values)      {          using (SqlConnection conn = new SqlConnection("Data Source=127.0.0.1;Initial Catalog=testDB;Persist Security Info=True;User ID=sa;Password=123456"))          {              SqlCommand comm = new SqlCommand(sql, conn);              comm.CommandType = t;              if (values != null && values.Length > 0)                  comm.Parameters.AddRange(values);              SqlDataAdapter da = new SqlDataAdapter(comm);              DataSet ds = new DataSet();              try             {                  conn.Open();                  da.Fill(ds);                  return ds.Tables[0];              }              catch (Exception)              {                  return null;              }              finally             {                  conn.Close();                  conn.Dispose();              }          }      }  }
