seems like there’s multiple questions here – not sure which one(s) you’re asking.

1) how to format a date in format X or Y?
– You can use String.Format(“{0:MM/dd}”, yourDateTime) or yourDateTime.ToString(“MM/dd”) or whatever for that case. Add on /yyyy for the other case.

2) how to conditionally display format?
– various ways, but a simple one that I think would work fine is to just add into Page_Load the check, so something like: string format = cond ? “MM/dd/yyyy” : “MM/dd”; and then checkbox.Text = yourDateTime.ToString(format);

3) how to get the display to change on checkbox change?
– #2 combined with adding AutoPostBack=true on your checkbox(es)

If you can further clarify the question, in particular what parts of what you’re trying to do you’re having trouble with, it may help us provide better answers 🙂
