我在项目中从AvalonDock内容创建了一个DockingManager,我的请求非常简单:当我向LayoutDocumentPaneGroup添加文档时,我希望它是Active,Selected,而不仅仅是在LayoutDocumentPaneGroup的末尾添加仍然在第一个上激活文献。
我试图为我的documentView类实现一个“IsActive”属性,但它不起作用。
我在xaml文件中的对接管理器定义如下:
<dock:DockingManager DataContext="{Binding DockManagerViewModel}" DocumentsSource="{Binding Documents}" AnchorablesSource="{Binding Anchorables}">
<dock:DockingManager.Resources>
<!-- add views for specific ViewModels -->
<DataTemplate DataType="{x:Type vmdock:SampleDockWindowViewModel}">
<uscontrol:SampleDockWindowView />
</DataTemplate>
</dock:DockingManager.Resources>
<dock:DockingManager.LayoutItemContainerStyle>
<Style TargetType="{x:Type dockctrl:LayoutItem}">
<Setter Property="Title" Value="{Binding Model.Title}" />
<Setter Property="CloseCommand" Value="{Binding Model.CloseCommand}" />
<Setter Property="CanClose" Value="{Binding Model.CanClose}" />
</Style>
</dock:DockingManager.LayoutItemContainerStyle>
<dock:LayoutRoot>
<dock:LayoutPanel Orientation="Vertical">
<dock:LayoutDocumentPaneGroup>
<dock:LayoutDocumentPane />
</dock:LayoutDocumentPaneGroup>
<dock:LayoutAnchorablePaneGroup>
<dock:LayoutAnchorablePane />
</dock:LayoutAnchorablePaneGroup>
</dock:LayoutPanel>
</dock:LayoutRoot>
</dock:DockingManager>
我的documentView使用如下类定义:
公共抽象类DockWindowViewModel:BaseViewModel {#region Properties
#region CloseCommand
private ICommand _CloseCommand;
public ICommand CloseCommand
{
get
{
if (_CloseCommand == null)
_CloseCommand = new RelayCommand(call => Close());
return _CloseCommand;
}
}
#endregion
#region IsClosed
private bool _IsClosed;
public bool IsClosed
{
get { return _IsClosed; }
set
{
if (_IsClosed != value)
{
_IsClosed = value;
OnPropertyChanged(nameof(IsClosed));
}
}
}
#endregion
#region CanClose
private bool _CanClose;
public bool CanClose
{
get { return _CanClose; }
set
{
if (_CanClose != value)
{
_CanClose = value;
OnPropertyChanged(nameof(CanClose));
}
}
}
#endregion
#region Title
private string _Title;
public string Title
{
get { return _Title; }
set
{
if (_Title != value)
{
_Title = value;
OnPropertyChanged(nameof(Title));
}
}
}
#endregion
#endregion
public DockWindowViewModel()
{
CanClose = true;
IsClosed = false;
}
public void Close()
{
IsClosed = true;
}
终于找到了 !我发布结果是因为我认为我并不孤单......首先,我在文档视图定义中添加了一个新属性:
#region IsSelected
private bool _isSelected = false;
public bool IsSelected
{
get
{
return _isSelected;
}
set
{
if (_isSelected != value)
{
_isSelected = value;
OnPropertyChanged(nameof(IsSelected));
}
}
}
#endregion
但我还要将它作为我的XAML代码中的属性实现,如下所示:
<dock:DockingManager.LayoutItemContainerStyle>
<Style TargetType="{x:Type dockctrl:LayoutItem}">
<Setter Property="Title" Value="{Binding Model.Title}" />
<Setter Property="CloseCommand" Value="{Binding Model.CloseCommand}" />
<Setter Property="CanClose" Value="{Binding Model.CanClose}" />
**<Setter Property="IsSelected" Value="{Binding Model.IsSelected}" />**
</Style>
</dock:DockingManager.LayoutItemContainerStyle>
假设它对于在那里定义的LayoutContent的所有属性都起作用:LayoutDocument defined by AvalonDock
编辑:还需要添加“Mode = TwoWay”以便在所选内容更改时以编程方式更新,如下所示:
<Setter Property="IsSelected" Value="{Binding Model.IsSelected, Mode=TwoWay}" />
