我正在使用VS 2012 Ultimate,SAP Crystal Reports 13_0_13(最新版本) .

问题是,当我单击Crystal Report查看器的“下一页”按钮时,它会继续加载并且永远不会结束 .

我使用以下代码 .

protected void btn_search_Click(object sender, EventArgs e)

{

Session["ReportDocument"] = null;

loadReport(param1,param2,param3,param4);

}

loadReport 功能:

private void loadReport(string Param1, string Param2, string Param3, string param4)

{

CrystalReportViewer1.Visible = true;

ReportDocument reportDocument = new ReportDocument();

string reportPath = Server.MapPath(@"~/VacantAndFilledReports/rpt_vacantposts_HR.rpt");

reportDocument.Load(reportPath);

reportDocument.SetDatabaseLogon(ID, pass, serverName, databaseName);

reportDocument.SetParameterValue("@Param1", Param1);

reportDocument.SetParameterValue("@Param2", Param2);

reportDocument.SetParameterValue("@Param3", Param3);

reportDocument.SetParameterValue("Param4", Param4);

CrystalReportViewer1.ReuseParameterValuesOnRefresh = true;

CrystalReportViewer1.AutoDataBind = true;

CrystalReportViewer1.Zoom(88);

CrystalReportViewer1.ReportSource = reportDocument;

Session["ReportDocument"] = reportDocument;

}

我还将代码放在 Page_Init 中:

protected void Page_Init(object sender, EventArgs e)

{

if (Session["ReportDocument"] != null)

{

ReportDocument doc = (ReportDocument)Session["ReportDocument"];

CrystalReportViewer1.ReportSource = doc;

}

}

我已经搜索了很多关于Page Next按钮,所有帖子都是关于把代码放在 Page_Init 里面,但是如上所述尝试不适合我 .
