C# WPF - 如何修改 ToolBar.ButtonStyleKey 样式
我需要在鼠标悬停时显示工具栏按钮边框,否则隐藏它。我尝试执行以下操作:
<Style x:Key="{x:Static ToolBar.ButtonStyleKey}" TargetType="Button" BasedOn="{StaticResource {x:Static ToolBar.ButtonStyleKey}}">
<Setter Property="Foreground" Value="Blue"/>
<Setter Property="Control.Background" Value="Transparent" />
<Setter Property="Control.BorderBrush" Value="Transparent" />
<Setter Property="Control.BorderThickness" Value="1" />
<Setter Property="HorizontalAlignment" Value="Center"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Control.BorderBrush" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
但它没有按预期工作。我期望发生的是,鼠标悬停在边框上将变成红色,否则将是透明的。实际结果是它的行为类似于具有默认颜色的默认行为。
我肯定做错了什么。
有谁知道它是什么?
I have requirement to show the toolbar button border on mouse Hovering and otherwise hide it. I tried to do the following:
<Style x:Key="{x:Static ToolBar.ButtonStyleKey}" TargetType="Button" BasedOn="{StaticResource {x:Static ToolBar.ButtonStyleKey}}">
<Setter Property="Foreground" Value="Blue"/>
<Setter Property="Control.Background" Value="Transparent" />
<Setter Property="Control.BorderBrush" Value="Transparent" />
<Setter Property="Control.BorderThickness" Value="1" />
<Setter Property="HorizontalAlignment" Value="Center"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Control.BorderBrush" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
but it doesn't work as expected. What I expect to happen is that on mouse over the border will turn into red color otherwise will be transparent. Actual result was that it act like in the default behavior with the default colors.
Surely I'm doing something wrong.
Does anyone knows what is it?
