设置依赖项属性值时出错

Question

我有一个＆＃34; RoomType＆＃34; class，我创建了一个用户控件，可以将RoomType作为属性并显示名称。我试图将用户控件绑定到属性，如下所示：

public static readonly DependencyProperty TypeProperty =
        DependencyProperty.Register("Type", typeof(RoomType), typeof(RoomTypeBox));

    public RoomType Type
    {
        get
        {
            return (RoomType)GetValue(TypeProperty);
        }

        set
        {
            SetValue(TypeProperty, value);
        }
    }

问题在于，当我将值（一个RoomType对象）设置为属性时，它会抛出＆＃34; StackOverFlow Exception＆＃34;，我已经逐步调试，并且不存在无限循环。

这是UserControl的XAML

<UserControl x:Class="NH_Motel.Components.RoomTypeBox"

<Grid Name="Base" Height="28">

        <ColumnDefinition Width="0*" />
    </Grid.ColumnDefinitions>
    <Button Content="..." HorizontalAlignment="Right" x:Name="btnSelect" Width="47" d:LayoutOverrides="HorizontalAlignment, VerticalAlignment" Height="28" Style="{DynamicResource ButtonStyle3}" Click="btnSelect_Click" />
    <TextBox x:Name="txbText" Height="28" Margin="0,0,51,0" TextWrapping="Wrap" VerticalAlignment="Top" Template="{DynamicResource TextBoxControlTemplate1}" d:LayoutOverrides="HorizontalAlignment" Text="{Binding Type.Text}"/>
</Grid>

TextBox模板

<ControlTemplate x:Key="TextBoxControlTemplate1" TargetType="{x:Type TextBox}">
    <ControlTemplate.Resources>
        <Storyboard x:Key="OnLoaded1">
            <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)" Storyboard.TargetName="PART_ContentHost">
                <EasingColorKeyFrame KeyTime="0" Value="#FF6A7FCE"/>
            </ColorAnimationUsingKeyFrames>
        </Storyboard>
        <Storyboard x:Key="OnGotFocus1"/>
    </ControlTemplate.Resources>
    <Border BorderBrush="#FF494949" BorderThickness="1" CornerRadius="2">
        <ScrollViewer x:Name="PART_ContentHost" Background="#FFC1C5D4" FontFamily="Arial" BorderThickness="0"/>
    </Border>
    <ControlTemplate.Triggers>
        <EventTrigger RoutedEvent="FocusManager.GotFocus">
            <RemoveStoryboard BeginStoryboardName="OnLoaded1_BeginStoryboard"/>
            <BeginStoryboard x:Name="OnLoaded1_BeginStoryboard" Storyboard="{StaticResource OnLoaded1}"/>
        </EventTrigger>
    </ControlTemplate.Triggers>
</ControlTemplate>
