From the Edge: Handling Stretchables in Report Designer Section: Report Designer Chapter: Running R:BASE Your Way! Platform: R:BASE 7.x and V-8 "Turbo" for Windows Build: 7.1.79.30128 and higher The DB Memo is a special class of Report Controls called a stretchable. As the report prints, stretchable controls increase or decrease in height based on their content. This differs from static controls, which always print with the same height. When a band contains both static and stretchable controls, it is difficult to get the printed pages of a report to look exactly right because stretchable controls print at a height that is different from the one given in the report layout. The following properties can help you keep your reports looking good when Stretchables are used.
Stretch Applies to Stretchables only, and indicates whether or not the stretchable will adjust to its height based on content. A stretchable control with Stretch set to False (un-checked) behaves just like a static control, printing at the height defined in the report layout and cropping any content which extends beyond that height. When set to True (checked), Stretch causes the component to adjust its height based on the content.
StretchWithParent Applies only to shapes and lines and can be used to create border or background for a stretchable control. The 'Parent' in StretchWithParent refers to the band, since the band contains the controls.
ShiftWithParent Used by static controls that need to print after a stretchable has completed printing. For example. Let's say you need a description of a car, followed by the price. The price should appear below the description. In order to do this, you would place a DB Text control below the DB Memo, setting the ShiftWithParent property to True (checked). When the report prints, the DB Memo would print to completion and then the price would print beneath it.
OverFlow Whenever a stretchable is printing on additional pages, it is said to be overflowing. When a condition of OverFlow exist, other controls in the band may print again in order to clarify the content of the stretchable.
ReprintOnOverFlow This property applies to static controls only. Stretchable controls often have a set of static controls that put the content of the stretchable into context. For example, a DB Memo describing the features of a car might be preceded by the name of the model. If this DB Memo happened to overflow onto additional pages, it might be helpful to print the name of the model again so that the reader is reminded of the model to which the description pertains. In order to do this, you would set ReprintOnOverFlow to True (checked) for the model name.
