I want to show a schedule for a specific time frame (1 day, 1 week or 1 month). By calling the 'refreshCallBack' script I change the amount of days the scheduler has to show. So far so good, but when I'm going to scroll after changing the amount of days the scheduler throws an exception. After analyzing the problem I found out the schedulers 'Days' property is used to create the 'timeline' field. The problem here is that the 'Days' property always returns the default value of 1 day because it has no viewstate at callback. I see that the ScrollEVentArgs class has properties for the a viewStartDate and viewEndDate but nothing is done with them. Is this gonna be fixed in a next verion?
