Disabling unwanted dates from Datepicker?

[prabhafriend]

Is it possible to disable all dates lesser than a criterion in a Date picker? For example Start date of the project is 15/08/2010. When the user selects the End Date, all dates lesser than the Start date should be disabled, possible?

I'm not sure I understand your question. When you say disable all dates lesser than a criteria in a Date picker, are you saying:

A) You want to filter out the dates less than the Start Date?
Or
B) You want code to disable the datepicker object from working on dates that are less than the start date?
