Thanks, Ryan.
If I understand you correctly you're suggesting I create a Summary class with
those
setters and that function.
If the generateSummary() function returns a string, it would return the
generated
summary. At the end of this function I set the bindable summary property equal
to the
generated smry. So it would be model.summary = smry;
The only thing I'n not clear on is what is being called from the change event
of each of the
steppers. I guess I create a function called updateValues which instantiates
the Summary
class, passes in those values, and gets returned the summary string. The same
function
should be called from the change event of all controls that provide values to
the summary.
Is that it?
Thanks,
David
