Report Server运行后一直处于加载状态

描述：对Report server做了一个小练习，算是入门，但发现运行起来后，页面一直处于加载状态，不知为何？

解决：查了一下网上的资料，解决的方法是

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack) 
            {
                Show();
            }
        }
        public void Show()
        {
            try
            {
                string conn = System.Configuration.ConfigurationManager.ConnectionStrings["WX_TESTConnectionString"].ConnectionString;
                SqlConnection Sqlcon = new SqlConnection(conn);
                SqlCommand Sqlcmd = new SqlCommand("select * from Person", Sqlcon);
                SqlDataAdapter SqlDA = new SqlDataAdapter();
                DataSet ds = new DataSet();
                SqlDA.SelectCommand = Sqlcmd;
                SqlDA.Fill(ds);
                Sqlcon.Close();

                //重新绑定报表数据源
                this.ReportViewer1.LocalReport.ReportPath = AppDomain.CurrentDomain.BaseDirectory + "Report1.rdlc";
                this.ReportViewer1.LocalReport.DataSources.Clear();
                this.ReportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WebForms.ReportDataSource("DataSet1", ds.Tables[0]));
                this.ReportViewer1.LocalReport.Refresh();
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

关键就在于show()这个方法不能直接写在Page_Load，要判断回传页面（IsPostBack）在执行show()!
