매우 늦게 대답하지만이 문제를 발견하고 해결책을 찾아 냈습니다.
플라이 아웃 전용 맞춤 동작을 만들었습니다. 이렇게 사용했습니다. 플라이 아웃이 열릴 때 OpenActions
이 실행되고 플라이 아웃이 닫히면 CloseActions
이 실행됩니다. 이 경우 플라이 아웃을 열었을 때 맨 아래의 앱 표시 줄이 보이지 않기를 바랬습니다.
<Flyout Placement="Full">
<i:Interaction.Behaviors>
<behaviors:FlyoutBehavior>
<behaviors:FlyoutBehavior.OpenActions>
<core:ChangePropertyAction PropertyName="Visibility" Value="Collapsed" TargetObject="{Binding ElementName=CommandBar}" />
</behaviors:FlyoutBehavior.OpenActions>
<behaviors:FlyoutBehavior.CloseActions>
<core:ChangePropertyAction PropertyName="Visibility" Value="Visible" TargetObject="{Binding ElementName=CommandBar}" />
</behaviors:FlyoutBehavior.CloseActions>
</behaviors:FlyoutBehavior>
</i:Interaction.Behaviors>
<Grid>
...
</Grid>
</Flyout>
코드는 여기에 있습니다 :
class FlyoutBehavior : DependencyObject, IBehavior
{
public DependencyObject AssociatedObject { get; private set; }
public void Attach(Windows.UI.Xaml.DependencyObject associatedObject)
{
var flyout = associatedObject as FlyoutBase;
if (flyout == null)
throw new ArgumentException("FlyoutBehavior can be attached only to FlyoutBase");
AssociatedObject = associatedObject;
flyout.Opened += FlyoutOpened;
flyout.Closed += FlyoutClosed;
}
public void Detach()
{
var flyout = AssociatedObject as FlyoutBase;
if (flyout != null)
{
flyout.Opened -= FlyoutOpened;
flyout.Closed -= FlyoutClosed;
}
}
public static readonly DependencyProperty OpenActionsProperty =
DependencyProperty.Register("OpenActions", typeof(ActionCollection), typeof(FlyoutBehavior), new PropertyMetadata(null));
public ActionCollection OpenActions
{
get { return GetValue(OpenActionsProperty) as ActionCollection; }
set { SetValue(OpenActionsProperty, value); }
}
public static readonly DependencyProperty CloseActionsProperty =
DependencyProperty.Register("CloseActions", typeof(ActionCollection), typeof(FlyoutBehavior), new PropertyMetadata(null));
public ActionCollection CloseActions
{
get { return GetValue(CloseActionsProperty) as ActionCollection; }
set { SetValue(CloseActionsProperty, value); }
}
private void FlyoutOpened(object sender, object e)
{
foreach (IAction action in OpenActions)
{
action.Execute(AssociatedObject, null);
}
}
private void FlyoutClosed(object sender, object e)
{
foreach (IAction action in CloseActions)
{
action.Execute(AssociatedObject, null);
}
}
public FlyoutBehavior()
{
OpenActions = new ActionCollection();
CloseActions = new ActionCollection();
}
}
