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()!
