How to specify path to a report from another report? - sql-server

Question

I have SSRS on SQL Server 2012 and using report builder to build a drillthrough report. I have a table 6 rows and multiple columns. Each text box has some number in it and I should be able to click on these numbers and go to a different report. Both these reports would be under same folder on report server.
Problem:
I am able to do it until this point by following instructions at this page.
My problem is I can't use a static link as each text box should direct to it's own unique report. And when I "Specify a report:" using "Browse" button there or by providing static link, same link will be used for all the text boxes in the same column. What I need is to be able to specify path to the report which is of format /Folder_Name/<valueOfColumn1><valueOfColumn2><nameOfColumn3>;
What I tried:
So I tried to use "Expression" by clicking on "fx" button and provided link as =Globals!ReportFolderFields!column1.ValueFields!column2.ValueFields!column3.Name
Outcome:
When I try using above methods by using expression it doesn't throw any error but the text box is not clickable (doesn't turn pointer into an index finger). When I used static link by using "Browse" button, the same text box was clickable and was taking me to another report.
What am I missing here? Any pointer would be helpful.

The syntax of the field list in your formula needs a few changes. It looks like what you're really trying to do is concatenate several fields together, with a slash at several spots, in order to get the proper URL format.
Let's assume that the following elements resolve to the strings you need. (It can sometimes be helpful to verify these resolve to what you're expecting by inserting textboxes for each, individually, in a section of the report for troubleshooting; you can always remove them later.)
Globals!ReportFolder
Fields!column1.Value
Fields!column2.Value
Fields!column3.Name
If you would like to concatenate these together to use as a URL, together with a few slashes added in the correct places, you'll need to follow the SSRS conventions on operators in expressions, which results in something like this:
"/" & Globals!ReportFolder & "/" & Fields!column1.Value & Fields!column2.Value & Fields!column3.Name
as always, since this is an expression, it will need to start with an equals sign.
The expression builder doesn't insert operators for you between fields - it's not that smart...
