原文地址：asp.net中Repeater分页代码（可以加查询条件）作者：花心太郎

我的代码比个别代码要长一些，但是我的可以加查询条件，我测试了个别的代码，他们的代码如果在上面加油查询条件，不直接点击查询按钮，而是直接点击Repeater控件的“下一页”“尾页”等，会发生错误！我在这方面做了一些调整，所以代码相对要长一些：

aspx.cs文件

    {
       if (!this.IsPostBack)
       {
           this.lblNoPage.Text = "1";
           this.GridViewBind();
       }
    }

       this.lblTotalBar.Text = totalBar;
       ps.DataSource = ds.Tables[0].DefaultView;
