DataGrid分页(1)

分页的一种方法:

       aspx页面:

[url]http://www.w3.org/1999/xhtml[/url]" >

   


   

   

                    AutoGenerateColumns="False" Height="204px" OnPageIndexChanged="DataGrid1_PageIndexChanged"
            PageSize="5" Width="424px">
           
           
               
               
               
           
       

   

 后台aspx.cs代码:

 

public partial class page : System.Web.UI.Page
{
    int startIndex = 0;
    void Bind()//绑定数据方法
    {  //定义数据库连接对象
        SqlConnection cn = new SqlConnection("Data Source=Net33;Initial Catalog=QMSoftware;Integrated Security=True");
       //创建数据适配对象
       SqlDataAdapter da=new SqlDataAdapter("select ProductID ,Name ,Content from Product",cn);
       //创建DataSet对象
       DataSet ds=new DataSet();
       try
       {  //从指定的索引开始取PageSize条记录.
          da.Fill(ds,startIndex,DataGrid1.PageSize,"CurDataTable");
          da.Fill(ds,"AllDataTable");//填充数据集合
          //设置DataGrid控件实际要显示的项数
          DataGrid1.VirtualItemCount=ds.Tables["AllDataTable"].Rows.Count;
          //进行数据绑定
          DataGrid1.DataSource=ds.Tables["CurDataTable"];
          DataGrid1.DataBind();
       }
       catch
       {
            
           Page.RegisterClientScriptBlock("","");
           
       }
     }
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Bind();
        }
    }
    protected void DataGrid1_PageIndexChanged(object source, DataGridPageChangedEventArgs e)
    {
        DataGrid1.CurrentPageIndex=e.NewPageIndex;
        //取得当前页为止总共有多少条记录,以便在下一页就从该记录开始读取
        startIndex=DataGrid1.PageSize*DataGrid1.CurrentPageIndex;
        //取得绑定数据
        Bind();

    }
}
