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

 1  protected void Page_Load(object sender, EventArgs e)
 2         {
 3             if (!Page.IsPostBack) 
 4             {
 5                 Show();
 6             }
 7         }
 8         public void Show()
 9         {
10             try
11             {
12                 string conn = System.Configuration.ConfigurationManager.ConnectionStrings["WX_TESTConnectionString"].ConnectionString;
13                 SqlConnection Sqlcon = new SqlConnection(conn);
14                 SqlCommand Sqlcmd = new SqlCommand("select * from Person", Sqlcon);
15                 SqlDataAdapter SqlDA = new SqlDataAdapter();
16                 DataSet ds = new DataSet();
17                 SqlDA.SelectCommand = Sqlcmd;
18                 SqlDA.Fill(ds);
19                 Sqlcon.Close();
20 
21                 //重新绑定报表数据源
22                 this.ReportViewer1.LocalReport.ReportPath = AppDomain.CurrentDomain.BaseDirectory + "Report1.rdlc";
23                 this.ReportViewer1.LocalReport.DataSources.Clear();
24                 this.ReportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WebForms.ReportDataSource("DataSet1", ds.Tables[0]));
25                 this.ReportViewer1.LocalReport.Refresh();
26             }
27             catch (Exception ex)
28             {
29                 throw ex;
30             }
31         }

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()!
