个性化分页(2)

  上一节大家没有看到总的结构，这一节，我把代码全部贴出来，大家好好看看。

  <%@ Page Language="C#" %>
  <%@ Import Namespace="System.Data" %>
  <%@ Import Namespace="System.Data.SQL" %>
  <html>
  <script language="C#" runat="server">

  void Page_Load(Object sender, EventArgs e)
  {
   //判断是否隐藏PagerStyle-Mode
   if (chk1.Checked)
   {
   MyDataGrid.PagerStyle.Visible=true;
   }
   else
   {
   MyDataGrid.PagerStyle.Visible=false;
   }

   BindGrid();
  }

  ICollection CreateDataSource()
  {
   /*
   读取数据库的信息，获得DataView
   */
   SQLConnection MyConnection = new SQLConnection("server=localhost;uid=sa;pwd=123456;database=aspcn");
   SQLDataSetCommand MyDataSetCommand = new SQLDataSetCommand("select * from admin_enter order by Enter_Time desc",MyConnection);
   DataSet ds= new DataSet();
   MyDataSetCommand.FillDataSet(ds,"admin_enter");
   return ds.Tables["admin_enter"].DefaultView;
  }

  void PagerButtonClick(Object sender, EventArgs e)
  {
   //获得LinkButton的参数值
   String arg = ((LinkButton)sender).CommandArgument;

   switch(arg)
   {
   case ("next"):
   if (MyDataGrid.CurrentPageIndex < (MyDataGrid.PageCount - 1))
   MyDataGrid.CurrentPageIndex ++;
   break;
   case ("prev"):
   if (MyDataGrid.CurrentPageIndex > 0)
   MyDataGrid.CurrentPageIndex --;
   break;
   case ("last"):
   MyDataGrid.CurrentPageIndex = (MyDataGrid.PageCount - 1);
   break;
   default:
   //本页值
   MyDataGrid.CurrentPageIndex = arg.ToInt32();
   break;
   }
   BindGrid();
  }

  void MyDataGrid_Page(Object sender, DataGridPageChangedEventArgs e)
  {
   //处理按下数字的方法
   BindGrid();
  }

  void BindGrid()
  {
   //将DataView绑定到DataGrid上去
   MyDataGrid.DataSource = CreateDataSource();
   MyDataGrid.DataBind();
   ShowStats();
  }

  void ShowStats()
  {
   //显示页面信息
   lblCurrentIndex.Text = "当前页数为： " + ((int)MyDataGrid.CurrentPageIndex+1);
   lblPageCount.Text = "总页数是： " + MyDataGrid.PageCount;
  }
