I am working on an application that generates a user defined form.  One of the requirements is: 

Allow the form designer to set the max number of characters that can be entered into a XamTextEditor.  During data entry, make the XamTextEditor the appropriate size for the max number of characters.

Example:

XamTextEditor A’s max length = 32 chars

XamTextEditor B’s max length = 1 char

XamTextEditor C’s max length = 10 chars

When these XamTextEditor are displayed, A needs to be long enough to hold 32 characters, B only 1, C only 10.  It is ok if they are a bit wide, like 34, 3, and 12 respectfully.  How would one go about figuring how wide to make the XamTextEditores?
