This may create a problem
if your window isn??™t large enough to fit all the content when everything is expanded. There
are several strategies for handling this problem:
??? You can set a minimum size for the window (using MinWidth and MinHeight) to make
sure it will fit everything even at its smallest.
??? You can set the SizeToContent property of the window so that it expands automatically
to fit the exact dimensions you need when you open or close an Expander. Ordinarily,
SizeToContent is set to Manual, but you can use Width or Height to make it expand or
contract in either dimension to accommodate its content.
??? You can limit the size of the Expander by hard-coding its Height and Width. Unfortunately,
this is likely to truncate the content that??™s inside if it??™s too large.
??? You can create a scrollable expandable region using the ScrollViewer.
For the most part, these techniques are quite straightforward. The only one that requires
any further exploration is the combination of an Expander and a ScrollViewer. In order for this
approach to work, you need to hard-code the size for the ScrollViewer. Otherwise, it will simply
expand to fit its content.
Here??™s an example:
