Question

大家晚上好

我试图根据所述ListView的列值更改WPF ListView ContextMenu标头。具体来说，当列绑定到STATUS =“ Y”（保持）或“ N”（不保持）的值时，我想将其从Enable更改为Disable（反之亦然）。我尝试了以下方法：

 <ContextMenu.Resources>
     <Style TargetType="{x:Type MenuItem}">
         <Style.Triggers>
             <DataTrigger Binding="{Binding STATUS}" Value="Y">
                 <Setter Property="Header" Value="Enable" />
             </DataTrigger>
             <DataTrigger Binding="{Binding STATUS}" Value="N">
                 <Setter Property="Header" Value="Disable" />
             </DataTrigger>
          </Style.Triggers>
      </Style>
 </ContextMenu.Resources>

第二次尝试：

 <ListView.ContextMenu>
                <ContextMenu x:Name="cmlv">
                    <MenuItem x:Name="cmdisableenable">
                        <MenuItem.Resources>
                            <Style TargetType="{x:Type MenuItem}">
                                <Style.Triggers>
                                    <DataTrigger Binding="{Binding STATUS}" Value="Y">
                                        <Setter Property="Header" Value="Enable" />
                                    </DataTrigger>
                                    <DataTrigger Binding="{Binding STATUS}" Value="N">
                                        <Setter Property="Header" Value="Disable" />
                                    </DataTrigger>
                                </Style.Triggers>
                            </Style>
                        </MenuItem.Resources>
                    </MenuItem>
                </ContextMenu>
            </ListView.ContextMenu>

Answer 1

           <MenuItem>
                    <MenuItem.Resources>
                            <Style TargetType="{x:Type MenuItem}">
                                <Style.Triggers>
                                    <DataTrigger Binding="{Binding STATUS}" Value="Y">
                                        <Setter Property="Header" Value="Enable" />
                                    </DataTrigger>
                                    <DataTrigger Binding="{Binding STATUS}" Value="N">
                                        <Setter Property="Header" Value="Disable" />
                                    </DataTrigger>
                                </Style.Triggers>
                            </Style>

                    </MenuItem.Resources>
                </MenuItem>

您在MenuItem上应用了样式，因此取决于状态，标题将为“禁用”或“启用”，并确保您不为标题分配任何值

ListView：根据列值更改ContextMenu标头（样式触发器？）
