Question

我有一个上下文菜单，在右键单击列表视图时会调用它。在做了一些研究之后，我发现这就是你将命令绑定到menuitem的方法。

            <ListView.ContextMenu>
            <ContextMenu>
                <MenuItem Header="Delete">
                    <MenuItem.ItemContainerStyle>
                        <Style TargetType="{x:Type MenuItem}">
                            <Setter Property="Command" Value="{Binding Path=DataContext.DeleteCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListView}}"/>
                        </Style>
                    </MenuItem.ItemContainerStyle>
                </MenuItem>
            </ContextMenu>
        </ListView.ContextMenu>

任何关于命令为什么不被解雇的帮助都会非常感激。感谢。

<MenuItem Header="Delete" Command="{Binding DeleteCommand}"/>

会为你做的。

当ItemContainerStyle ItemsSource为MenuItem时，会使用

$scope.typeofnotification =[{name:'offer', imges: './resources/remote.png'}, {name:'discount', imges:'./resources/mic.png'}, {name:'upgrades', imges:'./resources/play-icon.png'}]; /*var len = $scope.typeofnotification.length*/ $scope.setNotificationImage = function(){ var notificationImage; for (var i = 0; i < $scope.typeofnotification.length; i++) { if($scope.notificationData[i].notificationType == $scope.typeofnotification[i].name) { return notificationImage = $scope.typeofnotification[i].imges; } } };。

单击MenuItem时不会调用命令
