Hello!

I have a ListView of appointments which are groped by date (month/year) if I scroll the list view I want to change the Date displayed on my RadCalendar but there is this specific problem while scrolling too fast on my list:

After too much digging with this issue I realized that having:

SelectedDate="{Binding SelectedDate, Mode=TwoWay}"
DisplayDate="{Binding CalendarDisplayDate, Mode=TwoWay}"

 

On my scroll event listener, causes a small UI thread blocking issue that is visible on both platforms (iOS/Android (slightly more visible) ), in small words, there is a small delay on my UI while updating the DisplayDate property.

My question:

Is this property to costly (in memory) on the calendar or why I am experiencing this issue? Is there a workaround for this?

Hi Adam,

Please, find attached a small example, which does not seem to suffer visible delays when changing DisplayDate. Note, that you do not need to update it if the new value is within the same month. Please, give this example a try and let me know if it works for you.

Best regards,
