Remarks

The XRLabel control is considered to have a null value, if its Text property returns null ( Nothing in Visual Basic) or String.Empty.

Note

When the XRLabel control displays a summary function‘s result, the ProcessNullValues property is disabled at design time and does nothing at runtime because null values are processed before summary functions are calculated.
