您要求的报告需要更多信息 [英] The report you requested requires further information

问题描述

如何在不提供此消息和登录提示的情况下使报告正常工作？

in在sample.aspx中写入代码：

 <  < span class =code-leadattribute> CR：CrystalReportViewer     ID   =  CrystalReportViewer1      runat   =  server    AutoDataBind   =  true    /  >  

在sample.aspx.cs中，信息objInformation;

 ConnectionInfo connectionInfo =  new  ConnectionInfo（）; 
 
 受保护  void  Page_Load（对象发​​件人，EventArgs e）
 {
 尝试 
 {
 
 SetDBLogonForReport（connectionInfo ）; 
 objInformation =  new 信息（）; 
 DataSet ds =  new  DataSet（）; 
 ds = objInformation.GetAllInformation（）; 
 ReportDocument rpt =  new  ReportDocument（）; 
 rpt.Load（Server.MapPath（ 〜/ Reports / CrystalReport.rpt） ）; 
 rpt.SetDataSource（ds）; 
 CrystalReportViewer1.ReportSource = rpt; 
 CrystalReportViewer1.DataBind（）; 
 
} 
  catch （例外情况）
 {
 
} 
 } 
 
  private   void  SetDBLogonForReport（ConnectionInfo connectionInfo）
 {
 TableLogOnInfos tableLogOnInfos = CrystalReportViewer1.LogOnInfo; 
  foreach （TableLogOnInfo tableLogOnInfo  in  tableLogOnInfos）
 {
 tableLogOnInfo。 ConnectionInfo = connectionInfo; 
 connectionInfo.DatabaseName =   DatabaseName; 
 connectionInfo.UserID =   UserID; 
 connectionInfo.Password =  密码; 
} 
} 
 

但是我再次使报告正常工作而不提供此消息和登录提示？



它不允许我为DB名称输入任何内容。我正在使用VS 2010专业版的水晶报表，后端DB是本地机器上的Sql server。 IIS 5.2也在同一台机器上（XP教授）。

我使用的控件是CrystalReportsPartsViewer。请帮助解决问题，Visual Studio 2010的新功能。

解决方案

看起来您设置了登录参数但尚未应用它。

< pre lang =cs> CrystalReportViewer1.SetDatabaseLogon（ myUsername， myPassword）;

我遇到了同样的问题，但我找到了一个简单的解决方案。你只需要用数据表替换数据集，它就可以正常工作..

how do i get the report to work correctly without giving this message and login prompt?
in have write code in sample.aspx :

<CR:CrystalReportViewer ID="CrystalReportViewer1"  runat="server" AutoDataBind="true" />

In sample.aspx.cs, Information objInformation;

ConnectionInfo connectionInfo = new ConnectionInfo();

protected void Page_Load(object sender, EventArgs e)
{
    try
    {

        SetDBLogonForReport(connectionInfo);
        objInformation = new Information();
        DataSet ds = new DataSet();
        ds = objInformation.GetAllInformation();
        ReportDocument rpt = new ReportDocument();
        rpt.Load(Server.MapPath("~/Reports/CrystalReport.rpt"));
        rpt.SetDataSource(ds);
        CrystalReportViewer1.ReportSource = rpt;
        CrystalReportViewer1.DataBind();

              }
    catch(Exception ex)
    {

    }
}

private void SetDBLogonForReport(ConnectionInfo connectionInfo)
{
    TableLogOnInfos tableLogOnInfos = CrystalReportViewer1.LogOnInfo;
    foreach (TableLogOnInfo tableLogOnInfo in tableLogOnInfos)
    {
        tableLogOnInfo.ConnectionInfo = connectionInfo;
       connectionInfo.DatabaseName = "DatabaseName ";
        connectionInfo.UserID = "UserID ";
        connectionInfo.Password = "Password ";
    }
}

but again i get the report to work correctly without giving this message and login prompt?

It will not allow me to enter anything for DB name. I am using crystal reports for VS 2010 professional, backend DB is Sql server which is on local machine. IIS 5.2 is also on same machine (XP prof).
The control that I am using is CrystalReportsPartsViewer. Please help with issue, new with Visual Studio 2010.

解决方案

Looks like you set the logon parameters but have not applied it.

CrystalReportViewer1.SetDatabaseLogon("myUsername", "myPassword");

I have the same problem but I find a simple solution to it. you just need to replace dataset with the data table and it will work fine..
