FormView与GridView使用问题

有一个界面有GridView1,FormView1, SqlDataSource1，刚开始FormView1跟Gridview1同时绑定sqlDatasource1，
但点击查找按钮时改变了sqlDataSource1.SelectCommand后，按钮click同时写了 FormView1.PageIndex = GridView1.SelectedIndex;
但为什么Formview1还是原来没有过滤之前的数据

你应该没有触发formview1的onSelectedIndexChanged事件
你这样编有问题!!
你动态改变了sql语句,但按GridView1的SelectedIndexChanged事件时,还是原来的sql!!
将你动态改变了sql语句,放到Page_Load里,注意IsPstBack,而不是!IsPosBack!!    protected void Page_Load(object sender, EventArgs e)
    {
        if(IsPostBack)
            SqlDataSource1.SelectCommand = "select * from base_ygphoto where ygnumber between 1000 and 2000";     }
