  What is the intended way of closing fullscreen Calendar on Android?

  I’m playing with the dropdown sample in C1Input101 demo project. When I add DropDownMode=“FullScreen” to C1DropDown defintion, like so, it seems impossible to close calendar without selecting a date:

  <Grid>
      <c1:C1DropDown x:Name="dropdown" HorizontalOptions="FillAndExpand" VerticalOptions="Start" DropDownMode="FullScreen">
          <c1:C1DropDown.Header>
              <c1:C1MaskedEntry x:Name="mask" Mask="00/00/0000"/>
          </c1:C1DropDown.Header>
          <c1:C1DropDown.DropDown>
              <calendar:C1Calendar x:Name="calendar" HorizontalOptions="FillAndExpand" DayOfWeekFormat="d"  BackgroundColor="Transparent" WidthRequest="270" HeightRequest="270" />
          </c1:C1DropDown.DropDown>
      </c1:C1DropDown>
  </Grid>
  
  

  The natural way of dismissing a fullscreen view on Android would be pressing Back button, but in this case pressing Back button closes the calendar AND the underlying activity. Selecting a date dismisses the calendar, but I want to be able to dismiss it without making a selection.

  To dismiss the DropDown without selecting a date from the Calendar and not close the app on pressing the back button, please override the OnBackButtonPressed method in your xaml page as below:

  protected override bool OnBackButtonPressed()
          {
              if (Device.OS == TargetPlatform.Android && dropdown.IsDropDownOpen)
              {
                  dropdown.IsDropDownOpen = false;
                  return true;
              }            
              else
                  return base.OnBackButtonPressed();
          }
