Question

我正在使用WPF在C＃中将图像放置在网格布局中。我希望有一个鼠标单击事件，但如果未设置图像源，则永远不会触发该事件。有办法改变吗？无论是否设置了图像源，我都希望触发事件。

<Image Focusable="True" IsEnabled="True" Grid.Row="1" Grid.Column="0"
MouseLeftButtonDown="Image_MouseLeftButtonDown" MouseDown="Image_MouseDown" Stretch="Fill" />

除非设置了属性Source，否则永远不会触发鼠标事件。

Answer 1

将Image放入Grid并在网格上注册事件

<Grid Grid.Row="1" Background="White" Grid.Column="0" MouseLeftButtonDown="Image_MouseLeftButtonDown" MouseDown="Image_MouseDown">
  <Image Focusable="True" IsEnabled="True" Stretch="Fill" />
</Grid>

Answer 2

 <Grid>
 <Image Height="150" HorizontalAlignment="Left" Margin="218,18,0,0" Name="image1"   Stretch="Fill" VerticalAlignment="Top" Width="200" Source="path" MouseLeftButtonDown="image1_MouseLeftButtonDown" />
 </Grid>
