Specifying Display Values for a Control
You can configure your data source so that the display values in a list control are different from the actual filter values that are passed when a value is selected. You can use this ability to provide more user-friendly and localized values for selection from the control without extra modifications to your content.
Control display values can be configured using the ACCEPT property for a field in a synonym. You can set this property to reference a lookup column with actual filter values and a display column from an external procedure or synonym.
