How to prohibits the continual selection when there is a invalid date in mode "Range"
posted

In SelectType=Range mode， the selected dates should be continuous rather than continual

when there is a unselelctable date，How to prohibits the  continual selection.

4/4  4/5  4/7  4/8  are invalid dates.

What  I need is :

if my mousedown start at 4/1  and  stop at 4/4 , the selected collection should be{4/1, 4/2, 4/3 }

if my mousedown start at 4/1  and  stop at 4/6 , the selected collection should be{4/1, 4/2, 4/3 }, and 4/6 shouldn't be display with a selected status.

if my mousedown start at 4/1  and  stop at 4/19 , the selected collection should be{4/1, 4/2, 4/3 }, and 4/6,4/9~4/19 shouldn't be display with a selected status.

How to do it.

    Hello user12341234,

    I have been looking into your issue and in order to change the default behavior I can suggest you handle the SelectedDatesChanged event as follows:

            private void xamMonthCalendar1_SelectedDatesChanged(object sender, Infragistics.Windows.Editors.Events.SelectedDatesChangedEventArgs e)
        {
            
           for(int i=0;i<xamMonthCalendar1.SelectedDates.Count-1;i++)
               if (xamMonthCalendar1.SelectedDates[i + 1]- xamMonthCalendar1.SelectedDates[i] > new TimeSpan(1,0,0,0))
               {
                   for (int j = i + 1; j < xamMonthCalendar1.SelectedDates.Count;j++ )
                       xamMonthCalendar1.SelectedDates.RemoveAt(j);
                   
                   break;
               }
        }

     

     

    This way you can check if between the current select dates there is an interval longer than one day with not presented dates, and if there is – the code will remove all of the selected dates after the disabled time span. 

    If you need any additional assistance on this matter, please feel free to ask.
