Hello All,
This is the code I am using to set the back ground color of the cells in the calendar control based on the min date.
1)I open the calendar  the back color for all the dates less than the min date is showing up as red. Let us assume the min date is 6/12/2000
Now when I go to next month(i.e., 7/12/2000) the back color for all the cells in that month is supposed to be green. But this is not the case. Whats happening is that some of the Cells color is still Red and the others are green. But if i reopen the Calendar all the dates show up as Green. Now if I go back to 6/12/2000 all the dates including dates less than 12 th of June are showing up as Green too.
Is there any other event in which this code needs to be executed when i change the month using the arrow on the top of raddatepicker. I am using raddatetimepicker for winforms. Q3 2010 version. I do not see a viewchanged event here. Any help would be appreciated.

Thanks a lot.
