我试图在一个按钮上做一个简单的鼠标悬停效果,当鼠标结束时它会改变颜色,但颜色立即被更改为默认按钮背景…我该如何覆盖此行为？
这是我的代码：
Style myBtnStyle = new Style();
Trigger bla = new Trigger() { Property = IsMouSEOverProperty,Value = true };
bla.Setters.Add(new Setter(Control.BackgroundProperty,Brushes.Black));
myBtnStyle.Triggers.Add(bla);
button2.Style = myBtnStyle;
解决方法
根据
this post,这个花哨的动画被内置并被删除,你将需要覆盖你的Button的ControlTemplate.幸运的是,这不是太难了.我使用
this post作为源材料,并提出了以下风格,给你的想法.
<Style x:Key="MouSEOverButtonStyle" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <ControlTemplate.Resources> <Style x:Key="ShadowStyle"> <Setter Property="Control.Foreground" Value="LightGray" /> </Style> </ControlTemplate.Resources> <Border Name="border" BorderThickness="1" Padding="4,2" BorderBrush="DarkGray" CornerRadius="3" Background="{TemplateBinding Background}"> <Grid > <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" Name="contentShadow" Style="{StaticResource ShadowStyle}"> <ContentPresenter.RenderTransform> <TranslateTransform X="1.0" Y="1.0" /> </ContentPresenter.RenderTransform> </ContentPresenter> <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" Name="content"/> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsMouSEOver" Value="True"> <Setter Property="Background" Value="Beige" /> </Trigger> </Style.Triggers> </Style>
更新：
如果您在代码中应用了Style,并且不想使用ResourceDictionary(可能是更好的方法),您可以使用XamlReader.Load动态加载样式：
const string xaml = @"
<Style xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'
TargetType='Button'>
<Setter Property='Template'>
<!--- Omitted For Clarity --->
</Setter>
<Style.Triggers>
<Trigger Property='IsMouSEOver' Value='True'>
<Setter Property='Background' Value='Beige' />
</Trigger>
</Style.Triggers>
</Style>";
var encoding = new ASCIIEncoding();
var bytes = encoding.GetBytes(xaml);
var style = (Style)XamlReader.Load(new MemoryStream(bytes));
Button1.Style = style;
