Crystal Reports - “您请求的报告需要更多信息" [英] Crystal Reports - "The report you requested requires further information"

问题描述

我有一些使用 Crystal(Visual Studio 外部)创建的 Crystal Reports，现在已加载到 VS 项目中.在预览报表之前，我在报表和所有子报表中设置了这样的报表数据库信息.

I have some Crystal Reports that were created using Crystal (external to Visual Studio) and are now loaded in the VS project. Before the report is previewed I set up the report database information like this in the report and all subreports.

        var connectionInfo = new ConnectionInfo();
        connectionInfo.ServerName = "192.168.x.xxx";
        connectionInfo.DatabaseName = "xxxx";
        connectionInfo.Password = "xxxx";
        connectionInfo.UserID = "xxxx";
        connectionInfo.Type = ConnectionInfoType.SQL;
        connectionInfo.IntegratedSecurity = false;

        TableLogOnInfo logon = table.LogOnInfo;
        table.LogOnInfo.ConnectionInfo = connectionInfo;
        table.ApplyLogOnInfo(logon);

报表在最初预览时正确显示，但当我转到报表预览的下一页时，我收到消息您请求的报表需要更多信息"，并再次提示输入数据库登录信息.一旦我在这里输入它，我就不再被提示了.我设置的初始 ConnectionInfo 似乎没有超过第一页.

The report displays correctly when it is initially previewed but when I go to the next page in the report preview I get the message, "The report you requested requires further information" and are prompted for the database login information again. Once I have entered it here I am no longer prompted. It appears that the initial ConnectionInfo I set up is not sticking past the first page.

我正在使用 Crystal XI 和 Visual Studio 2008.

推荐答案

我发现修复错误的最佳方法是将问题发布到 StackOverflow 并在 5 分钟后自己解决.不用说，我解决了这个问题.

I have found the best way to fix a bug is to post the question to StackOverflow and 5 minutes later work it out yourself. Needless to say, I worked this out.

除了在报表对象中设置所有登录信息外，我还必须在 ASP.NET 的 Crystal Viewer 组件中进行设置.所以我只是写了一些这样的代码，一切正常，没有提示.

As well as setting all the log on info in the report objects, I also have to do it in the Crystal Viewer component in ASP.NET. So I just write some code like this and it all works, no prompts.

<CR:CrystalReportViewer Height="500px" ID="Viewer" runat="server" />

var connectionInfo = new ConnectionInfo();
    connectionInfo.ServerName = "192.168.x.xxx";
    connectionInfo.DatabaseName = "xxxx";
    connectionInfo.Password = "xxxx";
    connectionInfo.UserID = "xxxx";
    connectionInfo.Type = ConnectionInfoType.SQL;
    connectionInfo.IntegratedSecurity = false;

for (int i = 0; i < Viewer.LogOnInfo.Count; i++)
{
    Viewer.LogOnInfo[i].ConnectionInfo = connectionInfo;
}
