水晶报表多页的问题
您好，
我可以使用水晶报表的CrystalReportViewer的一份报告显示。它的工作很好。但是，如果数据很大，需要多页，然后只显示第一页。我怎么能显示所有的页面。这里是我的代码。
注:我使用的是ASP.NET，C＃
protected void Page_Load(object sender, EventArgs e)
{
string ReportName="";
string Parameter1="";
ReportName = Session["ReportName"].ToString();
Parameter1 = Session["Parameter1"].ToString();
ReportDocument rptDoc = new ReportDocument();
try
{
rptDoc = ShowReport(ReportName, Parameter1);
CrystalReportViewer1.ReportSource = rptDoc;
CrystalReportViewer1.RefreshReport();
CrystalReportViewer1.Visible = true;
CrystalReportViewer1.DataBind();
}
catch (Exception ex)
{
}
}
