WPF DockLayoutManager布局后的布局重置

初始化布局

            Logging.InfoBiz("初始化布局信息");
            dockLayoutManager = new DockLayoutManager();
            RestoreLayoutOptions.SetRemoveOldPanels(dockLayoutManager, false);
            RestoreLayoutOptions.SetAddNewPanels(dockLayoutManager, true);
            dockLayoutManager.DockingStyle = DockingStyle.VS2010;
            mainLayout.Children.Add(dockLayoutManager);

保存默认布局

            // 保存默认布局
            dockLayoutManager.SaveLayoutToStream(defaultDockLayoutStream);
            defaultDockLayoutStream.Flush();

恢复布局

            var layoutPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "layout.xml");
            if (File.Exists(layoutPath))
            {
                dockLayoutManager.ClosedPanels.Clear();
                dockLayoutManager.RestoreLayoutFromXml(layoutPath);
                foreach (var panel in dockLayoutManager.ClosedPanels.ToList())
                {
                    dockLayoutManager.DockController.Restore(panel);
                }
            }

1. 布局重置之前需要关闭活动区域

            var docPanel = (DocPanel)((IMainWindow)this).GetActiveDocPanel();
            if(docPanel!=null)
            {
                dockLayoutManager.DockController.Close(docPanel);
            }

2. 然后再恢复初始保存的布局

        protected void RestoreDefaultDockLayout()
        {
            var docPanel = (DocPanel)((IMainWindow)this).GetActiveDocPanel();
            if(docPanel!=null)
            {
                dockLayoutManager.DockController.Close(docPanel);
            }

            defaultDockLayoutStream.Seek(0, SeekOrigin.Begin);
            dockLayoutManager.RestoreLayoutFromStream(defaultDockLayoutStream);
            foreach (var panel in dockLayoutManager.ClosedPanels.ToList())
            {
                dockLayoutManager.DockController.Restore(panel);
            }
        }

3. 将布局保存到配置文件

            var layoutPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "layout.xml");
            dockLayoutManager.SaveLayoutToXml(layoutPath);

4. 切换布局中的活动区域

       private void OnWorkspacePanelCommandExecute(object obj)
        {
            BaseLayoutItem item = null;
            if (obj.Equals("1"))
            {
                item = this.ermlPanel;
            }
            else if (obj.Equals("2"))
            {
                item = this.serverPanel;
            }
            else if (obj.Equals("3"))
            {
                item = this.diagramPanel;
            }
            else if (obj.Equals("4"))
            {
                item = this.stdzPanel;
            }
            else if (obj.Equals("5"))
            {
                item = this.outputPanel;
            }
            else if (obj.Equals("6"))
            {
                item = this.reviewPanel;
            }
            else if (obj.Equals("7"))
            {
                item = this.explrModelSearchPanel;
            }
            else if (obj.Equals("8"))
            {
                item = this.naviPanel;
            }

            if (item.Visibility == Visibility.Visible)
            {
                item.Visibility = Visibility.Collapsed;
            }
            else
            {
                item.Visibility = Visibility.Visible;
                dockLayoutManager.Activate(item);
            }
        }
