如何从代码隐藏中实时更改按钮的整体样式?
我有一个闪烁的按钮。
我想在资源字典闪烁时更改整个按钮样式。
我想它会是这样的:
DesktopWindow.AlertButton.Style = (Style)DesktopWindow.Resources["GreenAlertButtonStyle"];
但这行不通。我该怎么做?我不能简单地更改背景颜色(尽管这就是我真正想做的),因为我想保留触发器。当我现在更改按钮的背景时,鼠标悬停触发器就会停止工作......
按钮:
<Style TargetType="Button" x:Key="BaseAlertButtonStyle">
<Setter Property="ToolTip" Value="Show Alert List"/>
<Setter Property="Effect" Value="{DynamicResource dropShadow}" />
<Setter Property="Background" Value="{DynamicResource AlertButtonBackground}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Border CornerRadius="5" x:Name="ButtonBorder" Margin="0,0,0,0"
VerticalAlignment="Stretch" BorderThickness="0"
BorderBrush="#ffffff" Padding="0"
Background="{TemplateBinding Background}"
HorizontalAlignment="Stretch">
<Image x:Name="alertImage">
<Image.Source>
<BitmapImage UriSource="/resources/alertIcon.png" />
</Image.Source>
</Image>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="{DynamicResource ButtonRolloverBackground}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我不想听到有关搜索此问题的消息......
I have a button that flashes.
I would like to change the entire button style from a resource dictionary when ever it flashes.
I would think it would be like this:
DesktopWindow.AlertButton.Style = (Style)DesktopWindow.Resources["GreenAlertButtonStyle"];
But that doesn't work. How do I do this? I cannot simply change the background color (although that's all I really want to do) because I want to preserve the triggers. When ever I change the background of the button right now, the mouseover triggers stop working....
The button:
<Style TargetType="Button" x:Key="BaseAlertButtonStyle">
<Setter Property="ToolTip" Value="Show Alert List"/>
<Setter Property="Effect" Value="{DynamicResource dropShadow}" />
<Setter Property="Background" Value="{DynamicResource AlertButtonBackground}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Border CornerRadius="5" x:Name="ButtonBorder" Margin="0,0,0,0"
VerticalAlignment="Stretch" BorderThickness="0"
BorderBrush="#ffffff" Padding="0"
Background="{TemplateBinding Background}"
HorizontalAlignment="Stretch">
<Image x:Name="alertImage">
<Image.Source>
<BitmapImage UriSource="/resources/alertIcon.png" />
</Image.Source>
</Image>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="{DynamicResource ButtonRolloverBackground}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I dont wanna hear it about doing a search for this issue....

Try:
明确设置背景后,您必须清除BackgroundProperty,然后设置新样式。
After setting background explicitly you have to clear BackgroundProperty and then set new style.
