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();
        }
    }
    /// <summary>

    /// </summary>

    {

        ps.DataSource = ds.Tables[0].DefaultView;
        ps.AllowPaging = true;
