listPicker wp8选择更改

我用windows phone工具包创建了列表选择器，代码如下:

<toolkit:ListPicker ExpansionMode="FullScreenOnly" x:Name="myLst" Header="Pilih Peta :" BorderThickness="2" BorderBrush="Black" SelectedIndex="-1" Grid.Row="2">
            <toolkit:ListPicker.FullModeItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding}" Margin="0 24 24 24" TextWrapping="Wrap" Style="{StaticResource PhoneTextTitle2Style}" />
                </DataTemplate>
            </toolkit:ListPicker.FullModeItemTemplate>
        </toolkit:ListPicker>

然后我添加数据在xaml.cs:

List<string> _tipe = new List<string>();
_tipe.Add("one");
_tipe.Add("two");
_tipe.Add("three");
myLst.ItemsSource = _tipe;

我想做的是在我的列表选择器中显示selectionChanged时显示MessageBox。如何?

在XAML中添加事件处理程序:

<toolkit:ListPicker SelectionChanged="ListPicker_SelectionChanged" 
        .......
        >
    .......
</toolkit:ListPicker>

使事件处理程序显示消息框:

private void ListPicker_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (myLst.SelectedItem != null)
        MessageBox.Show(myLst.SelectedItem.ToString());
}
