RDLC Actions:set up a textbox to open file on disk by providing the relative path to file,once the report is exported to PDF using localreport.Render

Question

I am trying to export the RDLC report as PDF with links to a file in a disk. I am not using the Report Server to export the report to PDF, But I am using the programmatic way to export to PDF using LocalReport.Render("PDF") API.

I am able to setup textbox actions to open a file in the disk by providing the complete path to the file. But I am not able to set up textbox actions to open file in a disk by providing the relative path. I will not always know the absolute path, I will always know the relative path.

I have tried the following to set up relative path. Textbox properties -> Actions -> Jump to URl with following values

• "//Sample.pdf"
• "\Sample.pdf"
• "file:\\Sample.pdf"

Any suggestions around how to set up links to a relative path in RDLC would be helpful.
