从RDLC XML字符串生成报告 [英] Generating report from rdlc xml string

问题描述

我生成报表时所面临的问题。

I'm facing an issue when generating reports.

我要生成动态使用的数据库中的所有数据，它的报告（源名称和RDLC报告店为XML字符串）

I should generate report dynamically using all data from database for it (source name and rdlc report that stores as xml string)

所以，我解决了问题，接下来方式：

So I solved problem next way:

1. 创建与报告XML字符串本地R​​DLC文件;



2. 设置文件的路径;

1. Create local rdlc file with report xml string;

2. Set path to the file;

var rViewer = new ReportViewer();
rViewer.LocalReport.ReportPath = @"Path to the generated xml rdlc file";
var dataSource = new ReportDataSource("DataSourceName", data);
rViewer.LocalReport.DataSources.Add(dataSource);

我能在直接指定代码隐藏报告XML字符串，而不是生成RDLC文件并设置路径呢？你能推荐一个更好的办法？

Could I specify in the code-behind directly Report XML String instead of generating the rdlc file and set path to it? Could you recommend a better way?

感谢您

推荐答案

是的，你可以提供它StringReader使用LoadReportDefinition像这样的对象，

Yes, You can provide it a StringReader object using LoadReportDefinition like so,

private void Page_Load(object sender, System.EventArgs e)
{
    NMBS.ViewModels.ViewModelReport Report = (Session["CurrentReport"] as NMBS.ViewModels.ViewModelReport);
ReportViewer.ProcessingMode = ProcessingMode.Local;
ReportViewer.PageCountMode = PageCountMode.Actual;

// Set report specifics.
ReportViewer.LocalReport.DisplayName = Report.Name;
ReportViewer.LocalReport.LoadReportDefinition(new System.IO.StringReader(Report.Definition));
foreach (ReportParameter Param in Report.Parameters)
{
    ReportViewer.LocalReport.SetParameters(Param);
}
foreach (ReportDataSource Rds in Report.Data)
{
    //Load Report Data.
    ReportViewer.LocalReport.DataSources.Add(Rds);
}
ReportViewer.CurrentPage = Report.CurrentPage;
ReportViewer.Width = Report.Width;

// Refresh the reports.
ReportViewer.LocalReport.Refresh();
}

在哪里Report.Defintion是包含该报告的定义的XML字符串。

Where Report.Defintion is the String containing the XML of the Report's Definition.
