Question

I have an Xdocument object which is populated with xml (the definition for a report -rdl). I would like to give the contents of this XDocument to the report viewer.

this.reportViewer1.LocalReport.LoadReportDefinition(); 

LoadReportDefinition only seems to take either TextReader or FileStream arguments….but my report definition is loaded within my XDocument? How can I stream the contents of my XDocument?

Answer 1

You can use the StringReader class like so:

using (var textReader = new StringReader(xDocument.ToString()))
{
  this.reportViewer1.LocalReport.LoadReportDefinition(textReader);
}

Or alternatively use a Stream:

using (var stream = new MemoryStream()) 
{
  xDocument.Save(stream);
  stream.Position = 0;
  this.reportViewer1.LocalReport.LoadReportDefinition(stream);
}
