急救:::::::RDLC报表问题：老是显示正在加载
环境：vs2012+windows server 2012



后台代码:

protected void Page_Load(object sender, EventArgs e)

        {           

            BLL.YUser bllUser = new BLL.YUser();

            this.ReportViewer1.LocalReport.ReportPath = "t1\\Report\\Report1.rdlc";

            this.ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("Test", bllUser.GetAllList().Tables[0]));

            this.ReportViewer1.LocalReport.Refresh();

        }

前台代码:

<form id="form1" runat="server">

        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

        <rsweb:ReportViewer ID="ReportViewer1" runat="server">

            

        </rsweb:ReportViewer>

        

    </form>

不知道为甚么会这样..
------解决方案--------------------
 BLL.YUser bllUser = new BLL.YUser();
            this.ReportViewer1.LocalReport.ReportPath = "t1\\Report\\Report1.rdlc";
            this.ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("Test", bllUser.GetAllList().Tables[0]));
            this.ReportViewer1.LocalReport.Refresh();
放到
 if (!IsPostBack)
{
}
里面试试
