SuggestionChange（）我找不到如何更改它。您无法访问DataTemplate中定义的TextBlock。您可以为控件定义依赖项属性，并为显示数据定义访问该属性的权限。请参阅下面的代码
class TutorialAwareButton : Button
{
public string RandomString
{
get { return (string)GetValue(RandomStringProperty); }
set { SetValue(RandomStringProperty, value); }
}
public static readonly DependencyProperty RandomStringProperty =
DependencyProperty.Register("RandomString", typeof(string), typeof(TutorialAwareButton), new PropertyMetadata(string.Empty));
}
<local:TutorialAwareButton x:Name="PropoButton"
Command="{Binding CmdCreated}"
BorderThickness="0" VerticalAlignment="Bottom"
HorizontalAlignment="Left" Width="410" Height="200">
<local:TutorialAwareButton.ContentTemplate>
<DataTemplate>
<StackPanel VerticalAlignment="Bottom">
<TextBlock x:Name="Exemples" TextWrapping="Wrap" FontSize="18" VerticalAlignment="Top" LineHeight="20" Text="{Binding ElementName=PropoButton,Path=RandomString}" FontFamily="Segoe UI Light" />
</StackPanel>
</DataTemplate>
</local:TutorialAwareButton.ContentTemplate>
</local:TutorialAwareButton>
您只需要访问DataTemplate之外的内容，就可以访问您要查找的上下文。因此，在绑定基中使用FindAncestor或ElementName=之类的东西来访问外部视图就足够了。哦，拼写为“示例”；）它看起来不错，但我不能使用AncerstorType:在类型“relativesource”中找不到属性“ancestortype”是的，我在Windows应用商店8应用程序上，所以我尝试了：_Text=“{Binding RandomString，relativesource={StaticResource TutorialAwareButton}”，出现了调试器错误。您可以尝试。元素绑定。
