c# - RibbonControlLibrary 中的问题

Question

我在 Microsoft 的RibbonControlLibrary. 我创建了一个简单的 WPF 应用程序，我正在使用RibbonControlLibrary它在顶部创建一个功能区栏。问题如下图所示。

问题是“某事”下的菜单仅扩展与左侧菜单中的项目一样多，即项目1，项目2 ...如果我在左侧菜单中增加一个项目，我会得到这个

但是Something下的菜单中缺少一些窗台项目。

下面是我正在使用的 XAML

 <Ribbon:Ribbon ItemsSource="{Binding Path=CSIMRibbonTabs}">
            <Ribbon:Ribbon.ApplicationMenu>
                <Ribbon:RibbonApplicationMenu CanUserResizeVertically="True" ItemsSource="{Binding Path=MainItem}">
                    <Ribbon:RibbonApplicationMenu.AuxiliaryPaneContent>
                        <Grid> 
                            <Grid.RowDefinitions>
                                <RowDefinition />
                                <RowDefinition Height="*"/>
                            </Grid.RowDefinitions>
                            <Border  >
                                <StackPanel  Orientation="Vertical">
                                    <Label Content="Something"  />
                                </StackPanel>
                            </Border>
                            <ItemsControl  Grid.Row="1" ItemsSource="{Binding Path=OtherItems}"/>
                        </Grid>
                    </Ribbon:RibbonApplicationMenu.AuxiliaryPaneContent>
                </Ribbon:RibbonApplicationMenu>
            </Ribbon:Ribbon.ApplicationMenu>
        </Ribbon:Ribbon>

代码

 public List<string> MainItem
            {
            get
                {
                    return new List<string>() { "Item1", "Item2", "Item3"};
                }
            }

        public List<string> OtherItems
        {
            get
            {
                return new List<string>() { "val1", "val2", "val3", "val4", "val5", "val6", "val7", "val8" };
            }
        }

我应该怎么做才能在列表中有项目的情况下扩展“某事”下的菜单？

尝试将以下属性添加到您的 Grid 元素：ScrollViewer.VerticalScrollBarVisibility="Auto"

                <Ribbon:RibbonApplicationMenu.AuxiliaryPaneContent> 
                    <Grid ScrollViewer.VerticalScrollBarVisibility="Auto">  
                        <Grid.RowDefinitions> 
                            <RowDefinition /> 
                            <RowDefinition Height="*"/> 
                        </Grid.RowDefinitions> 
                        <Border  > 
                            <StackPanel  Orientation="Vertical"> 
                                <Label Content="Something"  /> 
                            </StackPanel> 
                        </Border> 
                        <ItemsControl  Grid.Row="1" ItemsSource="{Binding Path=OtherItems}"/> 
                    </Grid> 
                </Ribbon:RibbonApplicationMenu.AuxiliaryPaneContent>
