This blog is part of my series Making Data Tell a Story With SSRS Properties.
Property: CanGrow and CanShrink
The purpose of these properties is to allow a text box to grow or reduce in size to fit a value.
To access the property, select a text box and go to CanGrow or CanShrink. The options for both are True or False.

CanGrow
True – the text box will grow in size to fit a large value (default).
False – the text box will not grow.
CanShrink
True – the text box will reduce in size to fit a small value.
False – the text box will not reduce (default).
Example: I have an order status report that includes a text box for comments. CanGrow is false, and CanShrink is false.
Showing an order that has no comment, the text box will remain its default size.

I have no order with a short comment. The text box remains the default size.

I set CanShrink to True. The text box reduces in size to fit the shorter comment.

I have another order with a longer comment. I set CanGrow to True. The text box enlarges in size to fix the longer comment.
