Crystal Reports in ASP.NET MVC

I know the use of server-side controls is a no-no in ASP.NET MVC, however we have a long list of crystal reports that the company has already produced for a previous application that I would like to utilize for our new ASP.NET MVC application.

Is there an appropri开发者_JAVA技巧ate way to use crystal reports in ASP.NET MVC? If so, how?

It is pretty simple actually. just add following references to your MVC project:

• CrystalDecisions.CrystalReports.Engine
• CrystalDecisions.ReportSource
• CrystalDecisions.Shared

use Action method like below:

• C# :

  using CrystalDecisions.CrystalReports.Engine;
  
  public ActionResult Report()
      {
          ReportClass rptH = new ReportClass();
          rptH.FileName = Server.MapPath("[reportName].rpt");
          rptH.Load();
          rptH.SetDataSource([datatable]);
          Stream stream = rptH.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
          return File(stream, "application/pdf");   
      }
  

• VB.NET :

   Imports CrystalDecisions.CrystalReports.Engine
  
   Public Function Report() As ActionResult
      Dim rptH As New ReportClass()
      rptH.FileName = Server.MapPath("[reportName].rpt")
      rptH.Load()
      rptH.SetDataSource([datatable])
      Dim stream As IO.Stream = rptH.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)
      Return File(stream, "application/pdf")
   End Function

We had/have a similar situation at work.

The solution we use:

• Create a seperate directory for reports
• Create normal ASPX pages for reports

We have not seen any issues (besides the normal Crystal ones) with this setup.

Just add this reference : using CrystalDecisions.CrystalReports.Engine;
than do this action :

using CrystalDecisions.CrystalReports.Engine;  
    public ActionResult Report()
            {
                List<Table> table = new List<Table>();
                ReportDocument rd = new ReportDocument();
                rd.Load(Path.Combine(Server.MapPath("~/Repport/CrystalReport1.rpt")));

                Response.Buffer = false;
                Response.ClearContent();
                Response.ClearHeaders();
                Stream stream = rd.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
                stream.Seek(0, SeekOrigin.Begin);


                return File(stream, "application/pdf", "Suivie Historique.pdf");


            }
