从MVVM中的视图模型绑定命令到WPF菜单 [英] Binding command to WPF menu from view model in MVVM

问题描述

大家好，

我有一个命令对象，我必须将所有菜单项绑定到同一个命令对象。我使用命令参数来区分不同的菜单项。

如何将Command对象绑定到视图模型中动态生成的菜单项？

我尝试过：

1。我试图直接在ViewModel中设置Command Object菜单。

2。我尝试使用SetBinding来设置命令。

但这些解决方案都不起作用。

它应该绑定如下所示。

< MenuItem.ItemContainerStyle> 
< Style TargetType =" {x：Type MenuItem}"> 
< Setter Property =" Command" Value =" {Binding DataContext.ImportRecentItemCommand，RelativeSource = {RelativeSource Mode = FindAncestor，AncestorType = {x：Type MenuItem}，AncestorLevel = 1}}" /> 
< Setter Property =" CommandParameter"值= QUOT; {结合}" /> 
< / Style> 
< /MenuItem.ItemContainerStyle>

Hi Guys,

I have one command object and i have to bind all menu items to same command object. I use the command parameter to differentiate between different menu items.

How can i bind the Command object to dynamically generated menu item in view model?

What i have tried:

1. I tried to set Command Object of menu directly in ViewModel.

2. I tried to use SetBinding to set the command.

But none of these solutions are working.

Hi,

It should bind as below.

         <MenuItem.ItemContainerStyle>
                <Style TargetType="{x:Type MenuItem}">
                    <Setter Property="Command" Value="{Binding DataContext.ImportRecentItemCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type MenuItem}, AncestorLevel=1}}" />
                    <Setter Property="CommandParameter" Value="{Binding}" />
                </Style>
            </MenuItem.ItemContainerStyle>
