我有一个奇怪的问题,希望你能帮助我。
我为按钮创建了一个样式,并在模板中添加了一些触发器。一个用于IsMouseOver,一个用于IsPressed。
两个触发器都有一个EnterAction和一个ExitAction动画模板的背景颜色。
当我将鼠标悬停在按钮上时,我可以看到颜色发生变化,但是在我单击按钮后,悬停触发器停止工作。
这是一个示例代码:
<Button Margin="142,130,214,138" Content="Hi Mum!">
<Button.Resources>
<Color x:Key="backgroundColor" A="255" R="52" G="152" B="219" />
<Color x:Key="hoverBackgroundColor" A="255" R="62" G="182" B="255" />
<Color x:Key="pressedBackgroundColor" A="255" R="42" G="122" B="175" />
</Button.Resources>
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
CornerRadius="6">
<Border.Background>
<SolidColorBrush x:Name="backgroundBrush" Color="{StaticResource backgroundColor}" />
</Border.Background>
<ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}"
Content="{TemplateBinding Content}"
ContentStringFormat="{TemplateBinding ContentStringFormat}"
Focusable="False"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Margin="{TemplateBinding Padding}"
RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
