Crystal reports crystal报表打印和导出不工作

我是.net开发者。现在我在和crystal report合作。当我打印或导出crystal report然后打印对话框时，当我按print时打开，则不会执行任何打印操作。此打印和导出在fire fox不起作用。只有chrome支持此功能。做这项工作需要额外的代码吗

课堂申报：

 public partial class EndUser_FS_File_History : System.Web.UI.Page
    {
        ReportDocument reportdocument = null;
        ..........

装载时水晶报告：

reportdocument = new ReportDocument();
                    string connectionString = ConfigurationManager.ConnectionStrings["FileSystemConnectionString"].ConnectionString;
                    SqlConnectionStringBuilder SConn = new SqlConnectionStringBuilder(connectionString);
                    reportdocument.Load(Server.MapPath(@"~/Admin/UserReport.rpt"));
                    reportdocument.SetDataSource(myDataSet);
                    reportdocument.DataSourceConnections[0].SetConnection(SConn.DataSource, SConn.InitialCatalog, SConn.UserID, SConn.Password);
                    CrystalReportViewer1.ReportSource = reportdocument;

以及在页面卸载事件中：

protected void Page_Unload(object sender, EventArgs e)
    {
        if (reportdocument != null)
        {
            reportdocument.Close();
            reportdocument.Dispose();
        }
        GC.Collect();
    }

仍然存在大量记录的问题：

有几个步骤：

在Pageload之前，将报表声明为

ReportDocument rpt = null;
protected void Page_Load(object sender, EventArgs e)
{
  try
     {
     rpt= new ReportName; //this is the name of your report
     // do all the logic here
     }
  catch()
     {
     }
}

protected void Page_Unload(object sender, EventArgs e)
{
  if(rpt!=null)
   {
    rpt.Close();
    rpt.Dispose();
   }
  GC.Collect();
}

如果出现打印对话框，则打印有问题，因为至少报告显示了该对话框，在某些情况下，javascript会导致问题，并且打印对话框根本不可见。另外一个问题是为最大作业限制而发布的。当我关闭时，dispose，gc.collect抛出未找到对象引用…我在过去几个小时内阅读了与我的问题相同的问题。是的，直到加载报告时才会出现此问题，您尝试处理相同的问题，尝试将dispose等放在Page_UnLoad方法中。这将为您提供一个WorkID，您可以尝试上面更新的部分。此处rpt=new ReportDocument（）；在这里，您将初始化您创建的报告。是的，它可以很好地处理少量记录。但在处理大量记录时仍然出现错误，因此更新了问题。reportdocument.Clone（）；替换为Clone by close（）；是的，我纠正它。我调试源代码，然后发现加载报告失败。在reportdocument.Load（Server.MapPath（@“~/Admin/UserReport.rpt”）；
