Expression in reports
Expression is a very interesting property in SSRS reports. It is mostly used to do customizations at runtime.

Type the following expression in the Edit Expression window, as shown in the screenshot:
=iif(RowNumber(Nothing)mod 3, "#e0e0e0", "#ffe0c0")
Save the template and go back to the PktCustTransList report for a preview.
The report should now appear with a different color on every third line when previewed, as seen in the following screenshot:
How it works…
Expressions are a powerful means through...
