wpf - 替换网格中的用户控件

Question

我的 xml 看起来像这样：

<UserControl>
    <Grid>
        ...
    <Grid>
    ...
    <Grid Grid.Row="3">
        <local:UserControl1 Visibility = "{Binding UserControl1Visibility}" />
        <local:UserControl2 Visibility = "{Binding UserControl2Visibility}" />
    </Grid>
</UserControl>

Control1Visibility 和 Control2Visibility 是我的 ViewModel 中的属性，但它不起作用。此网格无法动态显示两个用户控件。有人有想法吗？

虚拟机：

private Visibility userControl1Visibility = Visibility.Visible;

        public Visibility UserControl1Visibility
        {
            get { return userControl1Visibility; }
            set
            {
                if (userControl1Visibility != value)
                {
                    userControl1Visibility = value;
                    RaisePropertyChanged("UserControl1Visibility");
                }
            }
        }


        private Visibility userControl2Visibility = Visibility.Collapsed;

        public Visibility UserControl2Visibility
        {
            get { return userControl2Visibility ; }
            set
            {
                if (userControl2Visibility != value)
                {
                    userControl2Visibility = value;
                    RaisePropertyChanged("UserControl2Visibility");
                }
            }
        }

You have the names wrong - in the xaml you call them Control1Visibility and Control2Visibility, but in the ViewModel, you are calling them UserControl1Visibility and UserControl2Visibility. Change the names in one or the other, and make sure the PropertyChanged events are raised with the appropriate string.
