Zebra Striping in SQL Reporting Services

This is actually pretty simple and there are a couple of ways to get this done.  The easiest method would be to use an expression for the BackgroundColor property for the row.

1. Select the row(s) you wish to apply the zebra striping.
2. In the properties window, select the dropdown next to BackgroundColor and choose "<Expression>", this will open the expression editor.
3. Insert the following expression:
   =IIF(RowNumber(Nothing) Mod 2, '#E7E7E7', '#FFFFFF')

Note that the RowNumber function takes an argument for the scope, check the function reference for more details.
