Question

您好我正在尝试在WPF窗口中实现用户定义的类？

奇怪的是，我已经这样做了，但这次它不起作用，我找不到我的错误......

这是班级：

Namespace Controls

    Public Class WorkingPopup
        Inherits Primitives.Popup

        Public ReadOnly WorkingLabelProperty As DependencyProperty = DependencyProperty.Register("WorkingLabel", GetType(Label), GetType(WorkingPopup))
        Public ReadOnly WorkingProgressBarProperty As DependencyProperty = DependencyProperty.Register("WorkingProgressBar", GetType(ProgressBar), GetType(WorkingPopup))

        Private Property WorkingLabel As Label
            Get
                Return GetValue(WorkingLabelProperty)
            End Get
            Set(value As Label)
                SetValue(WorkingLabelProperty, value)
            End Set
        End Property
        Private Property WorkingProgressBar As ProgressBar
            Get
                Return GetValue(WorkingProgressBarProperty)
            End Get
            Set(value As ProgressBar)
                SetValue(WorkingProgressBarProperty, value)
            End Set
        End Property

        Public Sub New()
            MyBase.New()

            Placement = Primitives.PlacementMode.Center
            StaysOpen = True
            PopupAnimation = Primitives.PopupAnimation.Fade

            WorkingLabel = New Label With {.Visibility = Windows.Visibility.Visible, .Content = "Working", .ContentStringFormat = "{0} ..."}
            WorkingProgressBar = New ProgressBar With {.Height = 20, .Width = 200, .Margin = New Thickness(5)}

            Child = New Border

            With DirectCast(Child, Border)
                .BorderBrush = SystemColors.ActiveBorderBrush
                .Background = SystemColors.ControlLightLightBrush
                .BorderThickness = New Thickness(1)

                .Child = New StackPanel

                With DirectCast(.Child, StackPanel)
                    .Children.Add(WorkingLabel)
                    .Children.Add(WorkingProgressBar)
                End With
            End With
        End Sub

        'Some more irrelevant code
    End Class

End Namespace

这是我的XAML：

    <RibbonWindow x:Class="MainWindow"
              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
              xmlns:ctrl="clr-namespace:WpfApplication3.Controls"
              Title="MainWindow" Height="600" Width="800" WindowStartupLocation="CenterScreen" ResizeMode="CanResizeWithGrip">

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>

        <Grid.Children>
            <ctrl:WorkingPopup/>

        </Grid.Children>
    </Grid>
</RibbonWindow>

也许是因为它的星期一早上......但我没有得到它......
