Issue with pop

[Dotneter]

Hi,
In the SelectionChanged event of my calender, I put a Yes/No popup so the user can tell if he is sure to change the date or not.
Here is the code :
 
 

void calendar_SelectionChanged(object sender, SelectionChangedEventArgs e) 
if (Condition)
{        
        MessageBoxResult result =Popup.Show("Are you sure you want to change the selected dates ");                
        if (result == MessageBoxResult.OK)
          {
          MyFonction();
          }
}
else
{            
MyFonction(); 
}
       
}

the problem is when I select a date and I click on Cancel, the calendar does not seem to finish his "selection", when I hover it I can see the days changed to gray and I have the popup that appears again.
Is there any way to control the process of selection ?
For exemple if there was a method "StopSelection" I'll put it here :

MessageBoxResult result =Popup.Show("Are you sure you want to change the selected dates ");                         if (result == MessageBoxResult.OK)​         
{        
  MyFonction();       
   }
StopSelection();

I hope I was clear, please let me know if it's not the case.

Hello,

Could you please give us more details on how exactly you cancel the selection of RadCalendar?

Looking forward to your reply.
