C# 使用dependency属性为2个元素设置可见性true或false

我有这样的usercontrol：

<UserControls:Header Grid.Row="0" isVisiableEarnPoints="False"/>

这是页眉用户控件，我使用此控件来控制几个页面

 <Grid>
            <TextBlock Grid.Column="1" Style="{StaticResource PuzzleTalkHeader}"  Text="{Binding Path=LocalizedResources.GlobalApplicationTitle, Source={StaticResource LocalizedStrings}}" Grid.ColumnSpan="2"/>
            <Image x:Name="imgCoin" Grid.Column="3" Height="24" Width="24" Source="/Assets/Images/Coin.png" />
            <TextBlock x:Name="tbxEarnPoints" Grid.Column="5" Text="15000"/>
        </Grid>

如果isVisibleEarnPoints=True，那么我希望imgCoin和tbxEarnPoints应该是可见的，如果它是false，那么这些元素将隐藏

我正在尝试这样的事情，但是我不能得到结果，你能帮我吗

    public partial class Header : UserControl
    {
        public Header()
        {
            InitializeComponent();

        }

        //public bool isVisiableEarnPoints
        //{
        //  set
        //  {
        //      if(value)
        //      {
        //          imgCoin.Visibility = Visibility.Visible;
        //          tbxEarnPoints.Visibility = Visibility.Visible;
        //      }
        //      else
        //      {
        //          imgCoin.Visibility = Visibility.Collapsed;
        //          tbxEarnPoints.Visibility = Visibility.Collapsed;
        //      }
        //  }
        //}

        public int isVisiableEarnPoints { get; set; }

        public static readonly DependencyProperty DisplayTypeProperty = DependencyProperty.Register("isVisiableEarnPoints", typeof(isVisiableEarnPoints), typeof(Header), new PropertyMetadata(YourDPCallBack));

        private static void YourDPCallBack(DependencyObject instance, DependencyPropertyChangedEventArgs args)
        {
            Header control = (Header)instance;

        }
    }
}

根据评论更新问题：

[1] :

然后像这样绑定此属性：

<Image x:Name="imgCoin" Grid.Column="3" Height="24" Width="24" Source="/Assets/Images/Coin.png" Visibility="{Binding isVisiableEarnPoints, Converter={StaticResource VisibilityConverter}}"  />
        <TextBlock x:Name="tbxEarnPoints" Grid.Column="5" Text="15000" Visibility="{Binding isVisiableEarnPoints, Converter={StaticResource VisibilityConverter}}" />

并在usercontrol中使用，如下所示：

<UserControls:Header Grid.Row="0" isVisiableEarnPoints="False"/>

但它仍然不起作用

为此，要隐藏/显示的控件的int XAML绑定一个您更改的bool属性，并将其分配给每个控件，以便将接收到的布尔值转换为控件的适当属性

下面是实现自定义转换器的具体示例：

它是Silverlight，但概念是一样的

或者，如果框架提供的行为满足您的需求，则可以简单地使用它

这很简单。。但是为什么要创建dependency属性，可以直接将viewmodel属性附加到控件的Visibility

但是如果你想创建一个像IsVisibleEarnPoints这样的新属性，那么你必须创建DP

例如`

 public partial class YOUCLASS: UserControl
    {
        public YOUCLASS()
        {
            InitializeComponent();


        }
 public static readonly DependencyProperty IsVisibleEarnPointsProperty =
            DependencyProperty.Register("IsVisibleEarnPoints", typeof(bool), typeof(YOURCLASS), new UIPropertyMetadata((bool)false, OnStateChange));

        public bool IsVisibleEarnPoints
        {
            get
            {
                return (bool)GetValue(IsVisibleEarnPointsProperty );
            }
            set
            {
                SetValue(IsVisibleEarnPointsProperty , value);
            }
        }

        private static void OnStateChange(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            if (e.NewValue is bool)
            {
                var source = (YOURCLASS)d;
                source.SetState((bool)e.NewValue);
            }
        }

        public void SetState(bool isDisabled)
        {   

if(isDisabled)
{
imgecoin.Visibility=Visibility.Visible;
//same for other control
}
else
{
// Do whatever you want.
}




    }`

你想让我写Visibility={Binding true/false，Converter={StaticResource VisibilityConverter}}}吗？先生，我想像这样创建一个新属性：将该属性绑定到ViewModel的boolean属性，并将Converter分配给Converter accordinglyOK，我这样设置：Image x:Name=imgCoin Grid.Column=3 Height=24 Width=24 Source=/Assets/Images/Coin.png Visibility={Binding isvisiableernpoints，Converter={StaticResource VisibilityConverter}/>

 public partial class YOUCLASS: UserControl
    {
        public YOUCLASS()
        {
            InitializeComponent();


        }
 public static readonly DependencyProperty IsVisibleEarnPointsProperty =
            DependencyProperty.Register("IsVisibleEarnPoints", typeof(bool), typeof(YOURCLASS), new UIPropertyMetadata((bool)false, OnStateChange));

        public bool IsVisibleEarnPoints
        {
            get
            {
                return (bool)GetValue(IsVisibleEarnPointsProperty );
            }
            set
            {
                SetValue(IsVisibleEarnPointsProperty , value);
            }
        }

        private static void OnStateChange(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            if (e.NewValue is bool)
            {
                var source = (YOURCLASS)d;
                source.SetState((bool)e.NewValue);
            }
        }

        public void SetState(bool isDisabled)
        {   

if(isDisabled)
{
imgecoin.Visibility=Visibility.Visible;
//same for other control
}
else
{
// Do whatever you want.
}
