Empty Image Mouse Click

问题

I am placing an Image in a Grid layout in C# with WPF. I want to have a mouse click event for it, but if the Image source is not set then the event is never fired. Is there a way to change that? I want the event to fire regardless of if the Image source is set or not.

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

The mouse events are never fired unless the property Source is set.

回答1:

Place you Image inside a Grid and register the events on the Grid

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

 <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>
