아쉽게도 "LayoutDocumentPane"과 "LayoutAnchorablePane"은 모두 RegionAdapters의 포함/생성을 허용하지 않지만 "DockingManager"는 허용하지 않습니다. 한 가지 해결책은 DockingManager에 대한 RegionAdapter를 작성한 다음 시각적 트리에서 "LayoutDocuments"의 인스턴스를 관리하는 것입니다.
XAML은 다음과 같이 보일 것이다 :이 지역은 DockingManager 태그에 정의되어 있으며 LayoutPanel에서 하나의 LayoutDocumentPaneGroup가 존재
<ad:DockingManager Background="AliceBlue" x:Name="WorkspaceRegion" prism:RegionManager.RegionName="WorkspaceRegion">
<ad:LayoutRoot>
<ad:LayoutPanel>
<ad:LayoutDocumentPaneGroup>
<ad:LayoutDocumentPane>
</ad:LayoutDocumentPane>
</ad:LayoutDocumentPaneGroup>
</ad:LayoutPanel>
</ad:LayoutRoot>
</ad:DockingManager>
참고. LayoutDocumentPaneGroup의 LayoutDocumentPane은 "WorkspaceRegion"에 추가 할 뷰와 관련된 LayoutDocuments를 호스팅합니다. RegionAdapter 자체가 내가 설명 주석

프리즘이 RegionAdapter
의 존재를 알고 있도록 부트 스트 래퍼에 아래의 코드를 추가하는 것을 잊지 마세요 protected override RegionAdapterMappings ConfigureRegionAdapterMappings()
{
// Call base method
var mappings = base.ConfigureRegionAdapterMappings();
if (mappings == null) return null;
// Add custom mappings
mappings.RegisterMapping(typeof(DockingManager),
ServiceLocator.Current.GetInstance<AvalonDockRegionAdapter>());

Voilà. 나는 이것이 해결책의 가장 깨끗한 것이 아니라는 것을 알고 있지만 그것은 효과가있다. 동일한 접근법을 "LayoutAnchorablePane"에 쉽게 적용 할 수 있습니다.
길고 번영하는 라이브!
+1 : 'ILayoutDocumentPane'의 일부가 나를 도왔습니다 –
나는 행복합니다. :-) –
LayoutAnchorablePane 및 LayoutAnchorableDocument에 대한 어댑터가 있으며 때로는 어댑터를 등록하는 경우가 있습니다. 매우 실망합니다. – Vlad
