I would like to allow my users to click on a cell in a column of a Grid or Report section that contains the location of a PDF or JPG file (e.g. \data\jane_doe\resume.pdf) and have the PDF file displayed
1) make the column a URL
2) in the link click delegate of the section, the controlsource and the text of the field are passed, so you can know what action to initiate
3) that action would be to show the pdf, which you can do with Lianja.showDocument(…), or various other ways available in Lianja (e.g., DocumentView section).
