Property Value

Type	Description
ValueSuppressType	A ValueSuppressType enumeration value.

Available values:

Name	Description
Leave	Leaves all controls with null values as is.
Suppress	Removes all controls with null values and substitutes them with blank space.
SuppressAndShrink	Removes all controls with null values and shrinks the blank space between them. Note that you cannot use this mode for intersecting controls and vertical bands.

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.
