In Reporting Services (SSRS), the CanGrow property indicates whether the size of the text box can increase vertically according to its content.
Similarly, CanShrink decreases the height of the text box according to its content.
Controlling dynamically the height of report elements is only possible through these properties since the Height property cannot be bound to an expression.
These two properties are therefore useful to create reports which can be scaled to both small and large contents.
Unfortunately, CanGrow and CanShrink behave differently for each rendering extension.
