SSRS: Go Back Button in an Expression

ProblemLast week I was making a drillthrough report in SSRS for one of my clients and I had the need to make a (browser-like) Back button, to go back to the parent report for example. I know I did this before and it had something to do with history and (-1) but I couldn’t recall the syntax. So I thought I’d finally capture the solution in a blog post!

Solution
The key to the solution is the <Action> property of the <Text Box Properties>, which you’ll have to set to <Go to URL> and edit the expression with the following code:

=”javascript: history.go(-1)”

Do mind the casing here, because it’s case sensitive!
