Windows Phone 7：当用户单击图像时，我该怎么做？

Question

I use windows phone 7, with silverlight. I have an image on my page and I want that when the user clicks on the image an event will raise. Moreover, If it is possible I would like to know on which point of the image the user clicked.

Answer 1

Try this you probebly have to consider the image location relative to coordinates.. the coordinates are probebly relative to the root element.

<Image MouseLeftButtonUp="image_MouseLeftButtonUp"  x:Name="image" />

private void image_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
    {
        string x = e.GetPosition((UIElement)sender).X.ToString();
        string y = e.GetPosition((UIElement)sender).y.ToString();
    }

Answer 2

The WP7 Silverlight Toolkit (http://silverlight.codeplex.com/) has GestureListeners where you can attach a Tap Gesture to your image and catch the event.

    <Image>
    <toolkit:GestureService.GestureListener>
                <toolkit:GestureListener 
                    Tap="OnTap"/>
    </toolkit:GestureService.GestureListener>
    </Image>

我检查了所有可以绑定到图像标签的事件，应该有一个名为MouseLeftButtonDown和MouseLeftButtonUp看看是否能使您进入正确的轨道。
