我可以使用选中的事件更改边框背景的颜色，并且每次都选中/取消选中手动更改背景颜色，但我希望使用转换器或可视状态管理器或任何其他有效方式实现相同的效果，所以如何实现它。这是xaml
In this select query i used DATEADD function in where clause to get all rows with max(effective_date)>today_date
Try this:
select *,effective_date
from #tbl_group_txn
where effective_date>=dateadd(dd,datediff(dd,0,getdate()),-2)
group by GroupName,Indvd_id,effective_date,amount
order by Indvd_id
我想在选中并取消选中单选按钮时更改边框背景的颜色，以便如何实现它

根据您正在处理的工作量，灵活性和可重用性，有几种不同的解决方案可能。
编辑：以下代码适用于Windows（手机）8.1 RT，而不适用于Windows Phone Silverlight。将它留在这里供将来参考，因为无论如何Silverlight将被Windows 10上的Windows Runtime取代。
由于标准RadioButton已经在其可视树中内置了边框，并且为了获得最高的灵活性和可重用性，我创建了一个自定义控件（在Visual中称为模板化控件 Studio项目模板）源自RadioButton。
我提供了CheckedBrush和UncheckedBrush（默认红色/透明），因此您可以根据自己的意愿进行自定义。在XAML中设置其中一个值将覆盖默认值。
自定义控件的代码：
public sealed class MyRadioButton : RadioButton
{
public MyRadioButton()
{
this.DefaultStyleKey = typeof(MyRadioButton);
UnCheckedBrush = new SolidColorBrush(Colors.Transparent);
CheckedBrush = new SolidColorBrush(Colors.Red);
this.Checked += (sender, args) =>
{
this.CustomBackground = CheckedBrush;
};
this.Unchecked += (sender, args) =>
{
this.CustomBackground = UnCheckedBrush;
};
}
public static readonly DependencyProperty CustomBackgroundProperty = DependencyProperty.Register(
"CustomBackground", typeof (Brush), typeof (MyRadioButton), new PropertyMetadata(default(Brush)));
public static readonly DependencyProperty CheckedBrushProperty = DependencyProperty.Register(
"CheckedBrush", typeof(Brush), typeof(MyRadioButton), new PropertyMetadata(default(Brush)));
public static readonly DependencyProperty UnCheckedBrushProperty = DependencyProperty.Register(
"UnCheckedBrush", typeof(Brush), typeof(MyRadioButton), new PropertyMetadata(default(Brush)));
public Brush CustomBackground
{
get { return (Brush) GetValue(CustomBackgroundProperty); }
set { SetValue(CustomBackgroundProperty, value); }
}
public Brush CheckedBrush
{
get { return (Brush) GetValue(CheckedBrushProperty); }
set { SetValue(CheckedBrushProperty, value); }
}
public Brush UnCheckedBrush
{
get { return (Brush) GetValue(UnCheckedBrushProperty); }
set { SetValue(UnCheckedBrushProperty, value); }
}
}
下一步是在Themes / Generic.xaml文件中提供样式，这是默认的RadioButton样式的一个稍微调整的样式（用于背景）：
<Style TargetType="local:MyRadioButton">
<Setter Property="Foreground" Value="{ThemeResource RadioButtonContentForegroundThemeBrush}"/>
<Setter Property="Padding" Value="1,4,0,0" />
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="VerticalAlignment" Value="Center" />
<Setter Property="HorizontalContentAlignment" Value="Left" />
<Setter Property="VerticalContentAlignment" Value="Top" />
<Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
<Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
<Setter Property="Template">
<Setter.Value>

默认模板中唯一改变的是删除Background属性并更改Border控件上的Background。
你们都准备好使用它了：
<StackPanel Margin="100">
<RadioButton Content="Check 1" />
<local:MyRadioButton CheckedBrush="Blue" Content="Check 2" />
<local:MyRadioButton CheckedBrush="Green" Content="Check 3" />
</StackPanel>

我将实现一个视图模型类（参见MVVM pattern）并实现两个DependencyPropery的一个带复选框状态，一个带有border-color。使用数据绑定将相应的XAML属性绑定到这些属性。当复选框状态更改时，还会为边框颜色引发PropertyChanged事件。完成。
