asp下用ReportView查看RDLC报表传递参数的问题

[lhua_1225]

我在asp下用ReportView查看RDLC报表，查看时需要传入参数，代码如下

protected void Page_Load(object sender, EventArgs e)
{
ReportParameter rpdate = new ReportParameter("@ReceiptDate", "2010");

this.ReportViewer1.LocalReport.ReportPath = MapPath("InitReceipt.rdlc");
this.ReportViewer1.LocalReport.ReportEmbeddedResource = "InitReceipt.rdlc";
this.ReportViewer1.LocalReport.SetParameters(new ReportParameter[] { rpdate });

this.ReportViewer1.ShowParameterPrompts = false;

this.ReportViewer1.LocalReport.Refresh();
}

但是每次显示时ReportView总是显示Loadding......，并不断刷新页面，我把 this.ReportViewer1.LocalReport.SetParameters(new ReportParameter[] { rpdate });这行代码去掉就可以了。
