Hi,

I need to show a RDLC report in Acrobat PDF Viewer which should be integrated as activex control in a form in .net Windows Forms application.
Im using the same concept in web application, and the code for the same is as follows...

XML

dvpdf.Visible = true;
dvReport.Visible = false;
Warning[] warnings;
string[] streamIds;
string mimeType = string.Empty;
string encoding = string.Empty;
string extension = string.Empty;
byte[] bytes = this.ReportViewer1.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
String strfilename = System.IO.Path.GetRandomFileName();
using (FileStream fs = new FileStream(Server.MapPath("~/pdfoutput/") + strfilename + ".pdf", FileMode.Create))
{
fs.Write(bytes, 0, bytes.Length);
}
StringBuilder sb = new StringBuilder();
sb.Append("<object data='" + "pdfoutput/" + strfilename + ".pdf" + "' type='application/pdf' width='916' height='470'>");
sb.Append("</object>");
this.dvpdf.InnerHtml = sb.ToString();

from this it is showing the report in PDF format in Acrobat Reader which is installed on the machine.

Now, how it can be done in the windows forms application.

Please help me.

Thanks in advance. Regards
Sri

Do you mean export to PDF via code?

Hi Sandeep, thanks for your quick reply.
I'm able to show the rdlc report in ReportViewer1 and able to export it as pdf.
But, I want it to be shown in Acrobat Reader activex control.
I have added a COM component (axAcroPDF) to my forms toolbox and placed on a form besides ReportViewer1.

the exact current scenario is

ReportViewer1 is on "frmReport.cs [Design]" and the report is getting assigned to the report viewer through code like follows.

this.reportViewer1.LocalReport.ReportPath = Application.StartupPath + "\\Reports\\Legacy.rdlc";

now the rdlc is shown on the report viewer and able to export it.

----

the same way like above; I want my RDLC to be shown in Acrobat Reader activex (axAcroPDF).
in other words I want to show my RDLC in Acrobat Reader which is embedded in my "frmReport.cs [Design]"

can you give me an Idea or approach to get this done.

You already know how to render the report as a PDF, so you're over halfway there.

You should have the ability to use the ActiveX component you're working with to pass in a file path and display a saved file.

Therefore, your approach should be:
1) generate a filepath
2) render the RDLC to PDF at that location
3) pass the path to the activex control in question.

Note that if you're just hacking in something not purposed for this you might be violating a use agreement (i.e., if you're just stubbing in an Adobe DLL, this is a no-no). There are 3rd party PDF controls for .NET, so you shouldn't have trouble getting one for cheap or free.

Cheers.
