这就是我在WPF中重现这个问题的方法:
创建自定义控件:
public class TestCustomControl : Control
{
static TestCustomControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(TestCustomControl), new FrameworkPropertyMetadata(typeof(TestCustomControl)));
}
public string Text
{
get { return (string)GetValue(TextProperty); }
set { SetValue(TextProperty, value); }
}
// Using a DependencyProperty as the backing store for Text. This enables animation, styling, binding, etc...
public static readonly DependencyProperty TextProperty =
DependencyProperty.Register("Text", typeof(string), typeof(TestCustomControl), new PropertyMetadata("Hello"));
public double OffSet
{
get { return (double)GetValue(OffSetProperty); }
set { SetValue(OffSetProperty, value); }
}
// Using a DependencyProperty as the backing store for OffSet. This enables animation, styling, binding, etc...
public static readonly DependencyProperty OffSetProperty =
DependencyProperty.Register("OffSet", typeof(double), typeof(TestCustomControl), new PropertyMetadata(5.0));
}
在Generic.xaml文件中为它添加样式:
<Style TargetType="local:TestCustomControl">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:TestCustomControl">
<Grid>
<TextBlock Text="{TemplateBinding Text}"></TextBlock>
<TextBlock Text="{TemplateBinding Text}">
<TextBlock.RenderTransform>
<TranslateTransform X="{TemplateBinding OffSet}" Y="{TemplateBinding OffSet}"/>
<!--<TranslateTransform X="10" Y="10"/>-->
</TextBlock.RenderTransform>
</TextBlock>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
然后将其添加到主窗口:
<local:TestCustomControl OffSet="32" Text="the off set is not working" FontSize="36">
</local:TestCustomControl>
然后运行应用程序,事实证明“文本”工作正常,但“OffSet”不起作用。 我在Windows Phone 7开发环境中尝试过类似的东西,我得到了相同的结果。
我应该如何修改代码以使OffSet工作?

尝试:
{Binding Offset, RelativeSource={RelativeSource TemplatedParent}}

TemplateBing和RelativeSource都不起作用,所以如果你的目标是WP7.0(Silverlight 3),就不要忘了它。 使用其他一些方法来解决它。 实际上,每次更改“OffSet”时,我都会手动更改每个变换的X / Y值。
