我有一个这样的用户控件:
<UserControl>
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<HyperlinkButton Grid.Row="0" />
<TextBlock Name="textblock" Grid.Row="1"
Text="{Binding dailyText, ElementName=userControl}">
</TextBlock>
</Grid>
</UserControl>
但是,我不知道如何设置从主窗口到用户控件的样式?我已经解决了访问此类其他属性的问题:
public static readonly DependencyProperty MyContentProperty =
DependencyProperty.Register("MyContent", typeof(object), typeof(Day), null);
public object MyContent
{
get { return (object)GetValue(MyContentProperty ); }
set { SetValue(MyContentProperty , value); }
}
然后
<local:Day MyContent="Hello World" />
但是,它不适用于样式。样式没有变化。
谢谢。

下面是mainWindow部分。
<Page.Resources>
<Style TargetType="TextBlock" x:Name="MyTextBlockStyle">
<Setter Property="Foreground" Value="Blue" />
<Setter Property="SelectionHighlightColor" Value="Red"/>
<Setter Property="FontSize" Value="10"/>
</Style>
</Page.Resources>
<local:Day MyStyle="{StaticResource MyTextBlockStyle}">
userControl的背后代码部分
public static readonly DependencyProperty MyStyleProperty =
DependencyProperty.Register("MyStyle", typeof(Style), typeof(Day), null);
public Style MyStyle
{
get { return (Style)GetValue(MyStyleProperty); }
set { SetValue(MyStyleProperty, value); }
}
答案 0 :(得分:0)
您可以使用PropertyMetadata
进行初始化,并将Style
设置为TextBlock
。就像
public Style MyStyle
{
get { return (Style)GetValue(MyStyleProperty); }
set { SetValue(MyStyleProperty, value); }
}
public static readonly DependencyProperty MyStyleProperty =
DependencyProperty.Register("MyStyle", typeof(Style), typeof(Day),
new PropertyMetadata(null, OnStyleChange));
private static void OnStyleChange(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var control = d as Day;
control.textblock.Style = (Style)e.NewValue
}
