Rendering the ASP.NET local report directly to PDF

Hi,

Since it is not possible to print from a local report in ASP.Net is there anyway to directly render to a PDF or hide the Local report rendering and automatically goto the PDF either in the web page or as a popup.

Thanks

Hi,

You can try this code:

string path = @."D:/Folder/MyFile.pdf";
WebClient client = new WebClient();
Byte[] buffer = client.DownloadData(path);

if (buffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-length",buffer.Length.ToString());
Response.BinaryWrite(buffer);
}

Hope this helps,

Vivek

Can this be done on a report on a server and a parameter is passed?

For example, when a button is clicked in a page, then it will pass a parameter to SSRS and then, in turn, returns a PDF file. (So there's no need for a report viewer)

I am not sure if its possible. Please advise. Thanks!

Lloyd,

How are you returning the PDF file? SSRS will return only data (I do not have much experience in SSRS), I have worked on Crystal Reports and it exported idrectly to PDF.

If you have data then you can format and show it to PDF. You can change the Response.ContentType as I mentioned before or use some tools like:

Hi!

Thanks for the reply!

I'm thinking if this can be done. When I click the "Print" button, the report will be generated (PDF), and the standard pop up message of browser would come up, asking if the user would want to open or save the generated file.

Lloyd,

You can first call the SSRS on the Print button click and then bind the resulting data to some data bound control, such as a DataGrid or GridView. After the bind, you can change the Response.ContentType property to "pdf". See my blog entry for details:

You can also try an Open Source PDF Report Server Control:http://sourceforge.net/projects/npdf/

Hope this helps,
