我目前在视觉工作室网站中嵌入了一份水晶报告。我部署网站并将其安装在 IIS 上，并向用户提供链接，以便他们可以在全球范围内访问并查看此报告。这个系统一直运行良好。
但是，当我嵌入具有子报表的水晶报表时，凭据不会自动传递给子报表。当我调试解决方案时，初始报告打开正常，当我单击项目打开子报告时，水晶报告查看器要求我提供数据库登录凭据。
如何在代码中自动传递这些凭据，以便用户在水晶报表查看器中查看时不必输入代码。
下面是我在 default.aspx.cs 页面中使用的代码。它包含连接字符串。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
namespace CFIBInventory
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=HPL-WTS;Initial Catalog=Enterprise32;Persist Security Info=True;User ID=sa;Password=********");
DataSet1 ds = new DataSet1();
SqlDataAdapter adapter = new SqlDataAdapter("SELECT dbo.Material.MaterialCode, dbo.Material.CategoryCode, dbo.Material.Description, dbo.MaterialOnHand.LocationCode, dbo.Material.ValuationMethod, dbo.MaterialOnHand.Quantity FROM dbo.Material INNER JOIN dbo.MaterialOnHand ON dbo.Material.MaterialCode = dbo.MaterialOnHand.MaterialCode WHERE (dbo.Material.CategoryCode = 'CFIB3') AND (dbo.Material.ValuationMethod = 1) AND (dbo.Material.InactiveFlag = 0)", con);
adapter.Fill(ds.cfibInventory);
CrystalReport1 report = new CrystalReport1();
report.SetDataSource(ds);
CrystalReportViewer1.ReportSource = report;
CrystalReportViewer1.ToolPanelView = CrystalDecisions.Web.ToolPanelViewType.None;
}
}
}
水晶报表查看器通过以下代码嵌入到我的 .aspx 页面中：
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="CFIBInventory._Default" %>
<%@ Register assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" namespace="CrystalDecisions.Web" tagprefix="CR" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<meta http-equiv="X-UA-Compatible" content="IE=9"/>
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p>
</p>
<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server"
AutoDataBind="true" />
</asp:Content>
子报表的查询在子报表的数据库专家中。
顺便说一句，数据库正在连接到一台 windows server 2005 机器。我不相信它有公共访问设置，比如它自己的 IIS。以前没有子报告的报告安装在较新的 2012 服务器上，因为这就是数据库所在的位置。不确定机器是否与水晶报表查看器中的附加登录提示有关。
任何帮助都会很棒。先感谢您！
编辑：从 Nimesh 实施解决方案后
好吧，我添加了连接的连接类型，但是，Visual Studio 在“报告”下划线说：在声明之前不能使用局部变量“报告”。
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in report.Database.Tables )
和
foreach（报表中的 ReportDocument 子报表.Subreports）
我注意到我稍后在下面将报告声明为新的水晶报告1。因此，我将该声明移至 Nimesh 代码块上方，“report”的红色下划线消失了，但随后“crtableLogoninfo”的所有 6 个实例都以红色下划线显示错误：当前上下文中不存在名称“crtableLogoninfo”
任何进一步的帮助将不胜感激。
下面是我的代码现在的样子：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using CrystalDecisions.Shared;
using CrystalDecisions.CrystalReports.Engine;
namespace CFIBInventory
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//Nimesh code
ConnectionInfo crConnectionInfo = new ConnectionInfo();
crConnectionInfo.ServerName = "HPL-WTS";
crConnectionInfo.DatabaseName = "Enterprise32";
crConnectionInfo.UserID = "sa";
crConnectionInfo.Password = "*********";
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in report.Database.Tables)
{
crTableLogoninfo = CrTable.LogOnInfo;
crtableLogoninfo.ConnectionInfo = crConnectionInfo;
CrTable.ApplyLogOnInfo(crtableLogoninfo);
}
foreach (ReportDocument subreport in report.Subreports)
{
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in subreport.Database.Tables)
{
crtableLogoninfo = CrTable.LogOnInfo;
crtableLogoninfo.ConnectionInfo = crConnectionInfo;
CrTable.ApplyLogOnInfo(crtableLogoninfo);
}
} // nimesh code end
//Old connection string, i assume this shouldnt be here since nimesh code is for connecting
//SqlConnection con = new SqlConnection("Data Source=HPL-WTS;Initial Catalog=Enterprise32;Persist Security Info=True;User ID=sa;Password=123qwerTy987");
DataSet1 ds = new DataSet1();
SqlDataAdapter adapter = new SqlDataAdapter("SELECT dbo.Material.MaterialCode, dbo.Material.CategoryCode, dbo.Material.Description, dbo.MaterialOnHand.LocationCode, dbo.Material.ValuationMethod, dbo.MaterialOnHand.Quantity FROM dbo.Material INNER JOIN dbo.MaterialOnHand ON dbo.Material.MaterialCode = dbo.MaterialOnHand.MaterialCode WHERE (dbo.Material.CategoryCode = 'CFIB3') AND (dbo.Material.ValuationMethod = 1) AND (dbo.Material.InactiveFlag = 0)", con);
adapter.Fill(ds.cfibInventory);
CrystalReport1 report = new CrystalReport1();
// OLD CODE
//report.SetDataSource(ds);
CrystalReportViewer1.ReportSource = report;
CrystalReportViewer1.ToolPanelView = CrystalDecisions.Web.ToolPanelViewType.None;
}
}
}
