有一种方法来处理pin/unpin事件devexpress LayoutPanel

Question

我在LayoutGroup中有一些LayoutPanels。我需要处理pin/unpin事件，这样我就可以在UI的某个地方选中/取消选中复选框控件。我试过这样写:

 <dxd:LayoutPanel x:Name="OverviewPanel"
                             ItemWidth="200"
                             Caption="{Binding Source={StaticResource MainWindowResources}, Path=Resource.Overview}"
                             ShowCloseButton="False"
                             dxd:DockLayoutManager.DockItemCollapsed="OverviewPanel_DockItemCollapsed"
                             AllowDrag="False"
                             AllowFloat="False"
                             AllowContextMenu="False"
                             Padding="1"
                             dxd:AutoHideGroup.AutoHideType="Left"
                             >
                    <TextBox BorderThickness="0" />
                </dxd:LayoutPanel>

和后面的代码:

  private void OverviewPanel_DockItemCollapsed(object sender, DevExpress.Xpf.Docking.Base.DockItemCollapsedEventArgs e)
    {
        cOverview.IsChecked = false;
    }

这行不通。

LayoutGroup的父类是另一个LayoutGroup，它们都在DockLayoutManager中

使用DockLayoutManager。DockOperationCompleted事件:

XAML标记:

<dxd:DockLayoutManager 
    DockOperationCompleted="DockLayoutManager_DockOperationCompleted"
    >
    ...
</dxd:DockLayoutManager>

后台代码:

void DockLayoutManager_DockOperationCompleted(object sender, DockOperationCompletedEventArgs e) {
    switch(e.DockOperation) {
        case DevExpress.Xpf.Docking.DockOperation.Hide:
            // dock panel hidden to auto-hide tray(pinned)
            break;
        case DevExpress.Xpf.Docking.DockOperation.Dock:
            // dock panel docked to layout (e.g. unpinned from auto-hide tray)
            break;
    }
}
