C# 如何在xaml中单击时更改按钮图像
当用户将鼠标悬停在按钮上时,我可以像在XAML中那样更改按钮的图像:C# 如何在xaml中单击时更改按钮图像,c#,wpf,xaml,C#,Wpf,Xaml,当用户将鼠标悬停在按钮上时,我可以像在XAML中那样更改按钮的图像: <Page.Resources> <ImageBrush x:Key="troubleshooting_normal" ImageSource="/Images/troubleshooting_yellow.png" /> <ImageBrush x:Key="troubleshooting_hover" ImageSource="/Images/troubleshooting_g
<Page.Resources>
<ImageBrush x:Key="troubleshooting_normal" ImageSource="/Images/troubleshooting_yellow.png" />
<ImageBrush x:Key="troubleshooting_hover" ImageSource="/Images/troubleshooting_gray.png" />
<ControlTemplate TargetType="Button" x:Key="buttonTroubleshooting">
<Grid Name="button" Background="{StaticResource troubleshooting_normal}">
<ContentPresenter/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="button" Property="Background" Value="{StaticResource troubleshooting_hover}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Page.Resources>
<Button Name="ButtonTroubleShooting" Template="{StaticResource buttonTroubleshooting}" HorizontalAlignment="Left" Margin="287,109,0,0" VerticalAlignment="Top" Width="155" Height="155" Click="ButtonTroubleShooting_Click"/>
我想为用户单击按钮时添加第三个图像,我如何修改上述内容以实现此目的???只需根据属性添加另一个触发器:
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="button" Property="Background" Value="{StaticResource troubleshooting_pressed}" />
</Trigger>
用自己的模板重新开始的问题是,您将错过按钮上设置的许多属性,以使其看起来像某种方式。相反,如果您可以复制现有的按钮样式/模板,然后简单地覆盖您需要的内容,这不是很好吗?你可以 您只需右键单击按钮=>edit syle=>edit copy并按照提示进行操作。这将把所有按钮样式放在参考资料部分,您可以根据需要进行替代。不需要重新开始 这是为我自动生成的,我只是进去,用鼠标点击改变图像
