radcalendar SpecialDays remove | Winforms

[RONNY]

dear,

how can i remove selected specialdays in radcalendar?
i can't find the solution.

and other question is:
When i try with a "for" function remove all Specialdays, then it removes not all specialdays.
(specialday range from 10.10.2012 - 20.10.2012, only remove the following Days: 10,12,14,16,18,20.. between this days it does not remove the specialdays.) 

for (int i = 0; i < radCalendar1.SpecialDays.Count; i++)
            {
 
                radCalendar1.SpecialDays.Remove(radCalendar1.SpecialDays[i]);
 
 
            }

Thank you...


PS: sorry for my english, i hope is enough to find the solution....:-)

now i find a solution:

for (int i = 0; i < radCalendar1.SpecialDays.Count; i++)
                {
                    for (int a = 0; a < radCalendar1.SelectedDates.Count; a++)
                    {
                        if (radCalendar1.SpecialDays[i].Date == radCalendar1.SelectedDates[a].Date) radCalendar1.SpecialDays.Remove(radCalendar1.SpecialDays[i]);
                    }
 
                }

but this is very complicated......
mayby there is a better solution???

Hi Ronny,

Thank you for writing.

Your solution is good and needs very small modification because you deleting elements from collection while  iterating over it which is not good pattern. This is the reason why the code snippet from your first post deletes only half days in the range.You can read more about this pattern at this blog article :http://stackoverflow.com/questions/308466/how-to-modify-or-delete-items-from-an-enumerable-collection-while-iterating-thro

Here is the modified version of your code:

for (int i = radCalendar1.SpecialDays.Count -1; i >= 0; i--)
{
    for (int a = 0; a < radCalendar1.SelectedDates.Count; a++)
    {
        if (radCalendar1.SpecialDays[i].Date == radCalendar1.SelectedDates[a].Date)
        {
            radCalendar1.SpecialDays.Remove(radCalendar1.SpecialDays[i]);
            break;
        }
    }
}

Should you have any other questions, I will be glad to assist you.

All the best,
