I have a question, i have created calendar object by following the instruction from this video Selecting Arbitrary Date Ranges - YouTube
It runs successfully, but now i want to validate the value when the user input the date from calendar. I have two calendar object ('FROM' and 'TO') When user input 'TO' value smaller than 'FROM' VALUE, i want to validate the value and make 'TO' value same like 'FROM' Value. For ex : User input FROM DATE = 5/5/2015 and user input TO DATE = 1/5/2015. So i want to make TO DATE = 5/5/2015 like FROM DATE.
Anybody knows the method ? Really appreciate your help.
