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[]));
                 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()!
