在WPF图像中显示鼠标上的不同图像 [英] Showing different image on mouse over in WPF Image

问题描述

我有一个用于datagridtemplatecolumn的数据窗口

我试图在Image上鼠标上显示不同的图像。

鼠标悬停时，光标正在变化，但图像是不改变。

 <   DataTemplate     x：Key   =  MyDataTemplate    DataType   =  DataRowView >  
 <   StackPanel    方向  = 水平   已删除  = 透明 >  
 <  图片   保证金  =  0,0,0,0       宽度  =  50   高度  =  50   来源  =  {Binding Converter = {StaticResource SetImgToDG}}   工具提示  =  {Binding}   >  
 <   Image.Resources  >  
 <  样式    TargetType   =  {x：Type Image} >  
 <   Style.Triggers  >  
 <  触发器   属性  =  IsMouseOver < span class =code-attribute>  值  =  True >  
 <！ -   < span class =code-keyword> 悬停图片   - >   
 <   Setter    属性  = 光标   值  = 手   /  >  
 <   Setter    属性  = 来源   值  =  C：\Images\Coil3.png  /  >  
 <   / Trigger  >  
 <   / Style.Triggers  < span class =code-keyword>>  
 <   / Style  >  
 <   / Image.Resources  < span class =code-keyword>>  
 <   / Image  >  
 <   / StackPanel  >  
 <   / DataTemplate  >  

该绑定是否会产生问题??

如何解决？?? div class =h2_lin>解决方案

你的setter看起来不对劲。您不能提供文件系统上的值，而是提供应用程序中资源的值。

I have a datatemplate used for datagridtemplatecolumn
I am trying to show different image on mouse over in Image.
On mouse over, the cursor is changing but image is not changing.

<DataTemplate x:Key="MyDataTemplate" DataType="DataRowView">
        <StackPanel Orientation="Horizontal" removed="Transparent">
            <Image Margin="0,0,0,0"   Width="50" Height="50" Source="{Binding Converter={StaticResource SetImgToDG}}" ToolTip="{Binding}" >
                <Image.Resources>
                    <Style TargetType="{x:Type Image}">
                        <Style.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <!-- Hover image -->
                                <Setter Property="Cursor" Value="Hand"/>
                                <Setter Property="Source" Value="C:\Images\Coil3.png"/>
                            </Trigger>
                        </Style.Triggers>
                    </Style>
                </Image.Resources>
            </Image>
        </StackPanel>
    </DataTemplate>  

Is that binding creates the problem??
How to resolve it??

解决方案

Your setter looks wrong. You don''t provide values that are on the file system, but values that are resources in your app.
