Add custom code to a report to make it available for use in expressions.

To add code

1. On the Code tab of the report, enter your custom code in the provided text box using instance based Visual Basic .NET. For example:
   

   Function CalcDiscount (x As Double, y As Double, z As Double) As Double
   	Dim disc As Double
   	disc = (x * y * z)
   	Return disc
   End Function

2. On the Layout tab of the report, use your custom code in report item expressions with syntax like the following.

   =Code.CalcDiscount(Fields!Quantity.Value, Fields!Price.Value, Fields!Discount.Value)
