protected void Page_Load(object sender, EventArgs e)
        {
//这个不对吗？不是这样写的吗？
//我是条件查询,查询出来的数据得显示啊.但是显示一下就没了.
            if (XS.Rows.Count != 0 )
            {

                    }
                }
           
        }

求大神赐教.

那个分页是我在GV控件找的.

是控件里缺少了某个元素还是我Page_Load(object sender, EventArgs e) 方法不对？

或者都不对

求改造，求改正

[走出一条新道路]

if (!Page.IsPostBack) 这句的意思是页面第一次加载，所以你懂了吧

[q919905205]

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
databind();

}
} //第一次加载执行databind()行数
AspNetPager 控件下载注册到vs里面

[记忆斑驳的旧时光_]

不要IsPostBack的判断试试
