Question

如何在列表中的stackpanel上进行onclick？我有一个从WCF服务检索的数据列表。我目前的代码如下：

        <ListBox x:Name="Results" Height="450" HorizontalAlignment="Left" VerticalAlignment="Bottom" ItemsSource="{Binding Items}">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Margin="20,0,0,20"  >
                       <TextBlock Text="{Binding SearchVal}"  TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeMediumLarge}" />
                       <TextBlock Text="{Binding Category}"  TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeMedium}" />
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

我去了很多网站研究，我累了鼠标不能，Tap，Up了很多..

我已经使用了你提供的代码，但在ItemTapped中，我没有按钮，所以我改为按钮到TextBlock。但它不会起作用。

//I try changing button to TextBlock, wont work.
var selectedSearchBtn = sender as Button; //Assuming your trigger is a button UI element. 

        if (selectedSearchBtn != null)
        {
            var selectedVal = selectedSearchBtn.DataContext as TestMap.Classes.Global.Place;
            Classes.Global.searchedValue = "Test to get into the loop in main";

            if (selectedVal != null)
            {
                Classes.Global.posy = selectedVal.Y;
                Classes.Global.posx = selectedVal.X;

            }

            NavigationService.GoBack();
        }

See sample here

<ListBox x:Name="Results" Height="450" HorizontalAlignment="Left" VerticalAlignment="Bottom" ItemsSource="{Binding Items}">
                        <ListBox.ItemTemplate>
                            <DataTemplate>
                                <StackPanel Margin="20,0,0,20" Tap="ItemTapped">
                                    <TextBlock Text="{Binding SearchVal}"  TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeMediumLarge}" />
                                    <TextBlock Text="{Binding Category}"  TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeMedium}" />
                                </StackPanel>
                            </DataTemplate>
                        </ListBox.ItemTemplate>
                    </ListBox>

private void ItemTapped(object sender, GestureEventArgs e)
    {
        var element = sender as FrameworkElement; //

        if (element != null)
        {
            var selectedVal = element.DataContext as TestMap.Classes.Global.Place;
            Classes.Global.searchedValue = "Test to get into the loop in main";

            if (selectedVal != null)
            {
                Classes.Global.posy = selectedVal.Y;
                Classes.Global.posx = selectedVal.X;

            }

            NavigationService.GoBack();
        }
    }
