  • Blog Post: The Invisible ReportViewer

    An interesting bug report came in recently regarding toggling the Visible property on the ASP.Net ReportViewer. It’s fairly subtle and I don’t believe many people are running into it. But the solution isn’t obvious, so I want to make the information available in case you run into it...

    RDL and RDLC files contain expressions written in VB.Net. As .Net code, expressions can potentially perform any operations, including accessing the file system or running native code.

  • Blog Post: AsyncRendering and all the Baggage that Comes With It

    The AsyncRendering property on the ASP.Net ReportViewer control is one of the most misunderstood properties on the ReportViewer. And that’s our fault.
