WPF中Button的四种状态

在WPF中使用Button有时候需要让button响应鼠标的几种状态，虽然它本身也有响应的处理，但有时希望在它上面贴图片，在几种状态时可以随状态切换图片。此处用的是资源字典

类似：

 1 <Style x:Key="ButtonStyle34" TargetType="{x:Type Button}">
 2         <Setter Property="Template">
 3             <Setter.Value>
 4                 <ControlTemplate TargetType="{x:Type Button}">
 5                     <StackPanel Orientation="Horizontal" Background="Transparent" Margin="0,0,0,0" >
 6                         <Image Name="ImgBtnBg3" Margin="0,0,0,2" Source="/Resources/Res/Delete_I.png" Stretch="Fill" Width="54"/>
 7                     </StackPanel>
 8                     <ControlTemplate.Triggers>
 9                         <Trigger Property="IsMouseOver" Value="True">
10                             <Setter Property="Source" Value="/Resources/Res/Geng_II.png" TargetName="ImgBtnBg3"/>
11                         </Trigger>
12                         <Trigger Property="IsPressed" Value="True">
13                             <Setter Property="Source" Value="/Resources/Res/Geng_III.png" TargetName="ImgBtnBg3"/>
14                         </Trigger>
15                         <Trigger Property="IsEnabled" Value="False">
16                             <Setter Property="Source" Value="/Resources/Res/Delete_I.png" TargetName="ImgBtnBg3"/>
17                         </Trigger>
18                     </ControlTemplate.Triggers>
19                 </ControlTemplate>
20             </Setter.Value>
21         </Setter>
22 
23     </Style>

在页面：

<Button Style="{DynamicResource ButtonStyle34}" >

不光只有Button是这样其实很多控件都可以这样的比如 TabControl 里的 TabItem 也可以做成类似状态，基本上资源字典和button一样

 <Style x:Key="TabItemStyle6" TargetType="{x:Type TabItem}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type TabItem}">
                    <StackPanel Orientation="Horizontal" Margin="0,0,0,0" >
                        <Image Name="ImgBtnBg3" Source="/Resources/VLCIcon/RssIcon/LocalPlay_I.png" Stretch="Fill" Width="144"/>
                    </StackPanel>
                    <ControlTemplate.Triggers>
                                    <Trigger Property="IsMouseOver" Value="True">
                                        <Setter Property="Source" Value="/Resources/VLCIcon/RssIcon/LocalPlay_II.png" TargetName="ImgBtnBg3"/>
                                    </Trigger>
                                    <Trigger Property="IsSelected" Value="True">
                                        <Setter Property="Source" Value="/Resources/VLCIcon/RssIcon/LocalPlay_III.png" TargetName="ImgBtnBg3"/>
                                    </Trigger>
                                    <Trigger Property="IsEnabled" Value="False">
                                        <Setter Property="Source" Value="/Resources/VLCIcon/RssIcon/LocalPlay_III.png" TargetName="ImgBtnBg3"/>
                                    </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
