Date Picker with submit

Question

Hi, I have 2 Date Pickers: The first date Picker contains date of the beginning (P203_BDATE), the second contains date of the end (P203_EDATE).
I made item P203_EDATE with submit (I set HTML Form Element Attributes of P203_EDATE to onchange="doSubmit('P203_BDATE','P203_EDATE');" ), so submit works after choosing end date and I get rows between begin and end date. (I use tabular form)
My problems:
1.I don`t know how to clear items P203_BDATE,P203_EDATE to get all rows of the report (may be something like "no date" in calendar)
2. I want to do P203_BDATE with submit only if P203_EDATE is not null (if user will want to change the beginning of the period after the first filtering of data)
Does anybody know how to solve these?
Thanks a lot

Hi Suri.
1. Respect to clear the values of begin and end dates, for see all table records, what you should to do is the opposite to clear, cause you're using between condition. Then you will want to assign a low value for begin as '01/01/1956' and a high value for end date as '12/31/2060'. You can add other controls as Select List with Submit to determine the date ranges, or what you consider better.
2. To perform the submit only within your desired condition, you must add in the branch that fires the redirection to the same page, :P203_EDATE is not null as PL/SQL condition
