Change font color for a column when the value changes

You can define an expression for the font color. In Visual Studio/Business Intellligence:

1. Select the cell you want to alter the colour of the font in
2. Navigate to the Color listing in the Properties, and select it
3. Click the Dropdown arrow that appears next to the value it's current set to (typically Black)
4. Under the Web tab, select Expression (top of the list) - the Edit Expression dialog will appear

5. You can use the IIF in combination with the PREVIOUS function to compare values. IE:

   =IIF(Fields!Registrations.Value <> Previous(Fields!Registrations.Value), 
         "Black", 
         "Blue")
   

   If true, this expression will colour the font black -- if false, blue.
