如何添加水平分隔在动态创建的文本菜单？ [英] How to add horizontal separator in a dynamically created ContextMenu?

问题描述

我一直在寻找互联网上的解决方案，但未能我的样本中找到它。我需要补充的是从code产生的背后上下文菜单项之间的分隔符。我想这样的code线如下图所示但没有成功添加。

  this.Commands.Add（新ToolStripSeparator（））;
 

我想知道，如果有人可以提供帮助。谢谢你在前进。

右键菜单XAML：

 ＆LT;风格X：键=DataGridCellStyle的TargetType ={X：类型DataGridCell}＆GT;
    ＆LT; setter属性=文本菜单＆GT;
        ＆LT; Setter.Value＆GT;
            ＆LT;文本菜单的ItemsSource ={绑定命令}＆GT;
                ＆LT; ContextMenu.ItemContainerStyle＆GT;
                    ＆LT;风格的TargetType ={X：类型菜单项}＆GT;
                        ＆LT; setter属性=命令VALUE ={结合}/＆GT;
                        ＆LT; setter属性=标题VALUE ={绑定路径=文本}/＆GT;
                        ＆LT; setter属性=CommandParameterVALUE ={绑定路径=参数}/＆GT;
                    ＆LT; /样式和GT;
                ＆LT; /ContextMenu.ItemContainerStyle>
            ＆LT; /文本菜单＆GT;
        ＆LT; /Setter.Value>
    ＆LT; /二传手＆GT;
 

，在该方法中加入＃：

  this.Commands =新的ObservableCollection＆LT;＆的ICommand GT;（）;
        this.Commands.Add（MainWindow.AddRole1）;
        this.Commands.Add（MainWindow.AddRole2）;
        this.Commands.Add（MainWindow.AddRole3）;
        this.Commands.Add（MainWindow.AddRole4）;
        //this.Add(new ToolStripSeparator（））;
        this.Commands.Add（MainWindow.AddRole5）;
        this.Commands.Add（MainWindow.AddRole6）;
        this.Commands.Add（MainWindow.AddRole7）;
 

解决方案

或者，而不是让你的文本菜单绑定到命令的集合，将其绑定到FrameworkElements的集合，那么你可以直接添加任何的MenuItems或分离到集合并让菜单控制完成所有的模板....

 ＆LT;风格X：键=DataGridCellStyle的TargetType ={X：类型DataGridCell}＆GT;
    ＆LT; setter属性=文本菜单＆GT;
        ＆LT; Setter.Value＆GT;
            ＆LT;文本菜单的ItemsSource ={绑定命令}/＆GT;
        ＆LT; /Setter.Value>
    ＆LT; /二传手＆GT;
＆LT; /样式和GT;
 

C＃：

  this.Commands =新的ObservableCollection＆LT;＆FrameworkElement的GT;（）;this.Commands.Add（新菜单项{头=菜单项2，命令= MainWindow.AddRole1}）;
this.Commands.Add（新菜单项{头=菜单项2，命令= MainWindow.AddRole2}）;
this.Commands.Add（新菜单项{头=菜单项3，命令= MainWindow.AddRole3}）;
this.Commands.Add（新菜单项{头=菜单项4，命令= MainWindow.AddRole4}）;this.Commands.Add（新分隔符）;this.Commands.Add（新菜单项{头=菜单项5，命令= MainWindow.AddRole5}）;
this.Commands.Add（新菜单项{头=菜单项6，命令= MainWindow.AddRole6}）;
this.Commands.Add（新菜单项{头=菜单项7，命令= MainWindow.AddRole7}）;
 

就采用这种方法在我的应用程序 - 分隔看起来更好，这样也

。

I was looking for the solution on the internet but was not able to find it within my sample. I need to add a separator between Context menu item that are generated from code behind. I tried to add it with such code lines like below but without success.

this.Commands.Add(new ToolStripSeparator()); 

I am wondering if someone can help. Thank you in advance.

Context Menu XAML:

<Style x:Key="DataGridCellStyle" TargetType="{x:Type DataGridCell}">
    <Setter Property="ContextMenu">
        <Setter.Value>
            <ContextMenu ItemsSource="{Binding Commands}">
                <ContextMenu.ItemContainerStyle>
                    <Style TargetType="{x:Type MenuItem}">
                        <Setter Property="Command" Value="{Binding}" />
                        <Setter Property="Header" Value="{Binding Path=Text}" />
                        <Setter Property="CommandParameter" Value="{Binding Path=Parameter}" />
                    </Style>
                </ContextMenu.ItemContainerStyle>
            </ContextMenu>
        </Setter.Value>
    </Setter>

C# that added in the method:

this.Commands = new ObservableCollection<ICommand>();
        this.Commands.Add(MainWindow.AddRole1);
        this.Commands.Add(MainWindow.AddRole2);
        this.Commands.Add(MainWindow.AddRole3);
        this.Commands.Add(MainWindow.AddRole4);
        //this.Add(new ToolStripSeparator()); 
        this.Commands.Add(MainWindow.AddRole5);
        this.Commands.Add(MainWindow.AddRole6);
        this.Commands.Add(MainWindow.AddRole7); 

解决方案

Or, instead of having your ContextMenu bind to a collection of commands, bind it to a collection of FrameworkElements then you can add either MenuItems or Separators directly to the collection and let the Menu control do all the templating....

<Style x:Key="DataGridCellStyle" TargetType="{x:Type DataGridCell}">
    <Setter Property="ContextMenu">
        <Setter.Value>
            <ContextMenu ItemsSource="{Binding Commands}" />
        </Setter.Value>
    </Setter>
</Style>

C#:

this.Commands = new ObservableCollection<FrameworkElement>();

this.Commands.Add(new MenuItem {Header = "Menuitem 2", Command = MainWindow.AddRole1});
this.Commands.Add(new MenuItem {Header = "Menuitem 2", Command = MainWindow.AddRole2});
this.Commands.Add(new MenuItem {Header = "Menuitem 3", Command = MainWindow.AddRole3});
this.Commands.Add(new MenuItem {Header = "Menuitem 4", Command = MainWindow.AddRole4});

this.Commands.Add(new Separator);

this.Commands.Add(new MenuItem {Header = "Menuitem 5", Command = MainWindow.AddRole5});
this.Commands.Add(new MenuItem {Header = "Menuitem 6", Command = MainWindow.AddRole6});
this.Commands.Add(new MenuItem {Header = "Menuitem 7", Command = MainWindow.AddRole7});

Just used this approach in my app - the separator looks better this way also.
