WPF：使用TemplateBinding将整数绑定到TextBlock

我在WPF中有一个自定义控件.在这里我有一个类型为int的DependencyProperty.在自定义控件的模板中,我有一个TextBlock,我想在TextBlock中显示整数的值.但我不能让它上班.

我正在使用TemplateBinding.如果我使用相同的代码,但将DependencyProperty的类型更改为字符串,那么它可以正常工作.但我真的希望它是一个整数,我的应用程序的其余部分工作.

我该怎么做？

我已经编写了简化的代码来显示问题.首先定制控件：

public class MyCustomControl : Control
{
    static MyCustomControl()
    {
        DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomControl), new FrameworkPropertyMetadata(typeof(MyCustomControl)));

        MyIntegerProperty = DependencyProperty.Register("MyInteger", typeof(int), typeof(MyCustomControl), new FrameworkPropertyMetadata(0));
    }


    public int MyInteger
    {
        get
        {
            return (int)GetValue(MyCustomControl.MyIntegerProperty);
        }
        set
        {
            SetValue(MyCustomControl.MyIntegerProperty, value);
        }
    }
    public static readonly DependencyProperty MyIntegerProperty;
}

这是我的默认模板：

<Style TargetType="{x:Type local:MyCustomControl}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:MyCustomControl}">
                <Border BorderThickness="1" CornerRadius="4" BorderBrush="Black" Background="Azure">
                    <StackPanel Orientation="Vertical">
                        <TextBlock Text="{TemplateBinding MyInteger}" HorizontalAlignment="Center" />
                    </StackPanel>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

使用方法：

<Window x:Class="CustomControlBinding.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:CustomControlBinding"
    Title="MainWindow" Height="350" Width="525">
<Grid>
    <local:MyCustomControl Width="100" Height="100" MyInteger="456" />
</Grid>

我究竟做错了什么？

谢谢//大卫

<TextBlock Text="{Binding MyInteger, RelativeSource={RelativeSource TemplatedParent}}" HorizontalAlignment="Center" />

根据 this thread ,这是TemplateBinding的一个限制：

TemplateBinding is a lightweight  “binding”, it doesn’t support some  features of traditional Binding, such  as automatically type conversion using  the known type converters associated  with the target property
