Mousedown事件触发两次（WPF）
我目前正在尝试从简单网格上的图像捕获mousedown。我没有触发事件，只是它触发了两次。而且，由于两次单击最终将具有不同的状态（它将显示展开的图像），因此直接单击第二次会引起问题。
我当前的代码如下：
XAML
<Window x:Class=\"WpfApplication.MainWindow\"
xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"
xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"
Title=\"MainWindow\" Height=\"350\" Width=\"525\">
<Grid Background=\"Transparent\" x:Name=\"MainContent\" MouseDown=\"Generic_MouseDown\">
<Image Source=\"http://www.blogcdn.com/www.engadget.com/media/2011/05/welcome-kansas-city-google-high-speed-internet.jpg\" Height=\"100\" Width=\"100\" MouseDown=\"Generic_MouseDown\"/>
</Grid>
</Window>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Generic_MouseDown(object sender, MouseButtonEventArgs e)
{
if (((FrameworkElement)e.Source).GetType() == typeof(System.Windows.Controls.Image))
{
Console.Out.WriteLine(\"image clicked\");
}
else
{
Console.Out.WriteLine(\"grid clicked\");
}
}
}
