Name	Description
Leave	Leaves all controls with identical values as is.
Merge	Merges controls with consecutive identical values into a single control. Note that this mode ignores controls with null values. Use the control’s ProcessNullValues property to process controls with null values.
Suppress	Removes all controls with consecutive identical values except the first control. Substitutes the removed controls with blank space.
SuppressAndShrink	Does the same as the Suppress mode and then shrinks blank space. Note that this mode cannot be used for intersecting controls and vertical bands.
