1、引用  

xmlns:xcad="http://schemas.xceed.com/wpf/xaml/avalondock"

　　

2、xaml代码

   <xcad:DockingManager x:Name="dockManager" Grid.Row="1" Grid.Column="0" Background="#f1f1f1">
            <xcad:DockingManager.Theme>
                <xcad:AeroTheme/>
            </xcad:DockingManager.Theme>
            <xcad:LayoutRoot>
                <xcad:LayoutPanel >

                    <xcad:LayoutAnchorablePaneGroup DockWidth="220" >
                        <xcad:LayoutAnchorablePane>
                            <xcad:LayoutAnchorable Title="导航栏" ContentId="text1" CanHide="False" CanClose="False" CanFloat="False">
                                <Border Grid.Row="1" Grid.Column="0" IsHitTestVisible="True"  x:Name="barmune" BorderBrush="Transparent" />
                            </xcad:LayoutAnchorable>
                        </xcad:LayoutAnchorablePane>
                    </xcad:LayoutAnchorablePaneGroup>

                    <xcad:LayoutDocumentPane >
                        <xcad:LayoutDocument   ContentId="FirstPage" Title="首页  " CanClose="False" CanFloat="False">
                            //在此增加元素
                        </xcad:LayoutDocument>
                    </xcad:LayoutDocumentPane>
                </xcad:LayoutPanel>
            </xcad:LayoutRoot>
        </xcad:DockingManager>

3、增加选项卡　　

引用  Xceed.Wpf.AvalonDock.dll

 private void AddTab(string tabName)
        {
            var firstDocumentPane = dockManager.Layout.Descendents().OfType<LayoutDocumentPane>().FirstOrDefault();
            if (firstDocumentPane != null)
            {
                LayoutDocument ldoc = firstDocumentPane.Children.OfType<LayoutDocument>().Where(o => o.Title == tabName).FirstOrDefault();
                if (ldoc != null)
                {
                    ldoc.IsSelected = true;
                }
                else
                {
                    LayoutDocument doc = new LayoutDocument();
                    doc.CanFloat = false;
                   

                    var uc = new MyUserControl();//实例化UserControl

                    doc.Content = uc;
                    doc.Title = tabName;

                    firstDocumentPane.Children.Add(doc);
                    doc.IsActive = true;

                }
            }
