Question

I m writting aWindows Telephone App, in the GUI a have a list Box with many htons, some such as this

    <ListBox x:Name="List">
                        <ListBox.ItemTemplate>
                            <DataTemplate>
                                <Button Width="460" Height="100" Click="Click_B">
                                    <Button.Content>
                                        <StackPanel Orientation="Horizontal" Height="80" Width="400">    
                                            <TextBlock Width="200" Name="txtblockName" FontSize="22" Text="{Binding Name}" Height="40"/>
                                            <TextBlock Width="200" Name="txtblockUrl" FontSize="22" Text="{Binding Url}" Height="40"/>
                                        </StackPanel>
                                    </Button.Content>
                                </Button>                            
                            </DataTemplate>
                        </ListBox.ItemTemplate>
</ListBox>

当我点击布顿时,我需要获得“txtblock Url”文本的内容,我如何能够获得这一价值?

private void Click_B(object sender, RoutedEventArgs e)
        {
            Button source = (Button)e.OriginalSource;

        }

Answer 1

你们可以打破下面所示的排位等级。

private void Click_B(object sender, RoutedEventArgs e)
{
  string s = ((((sender as Button).Content) as StackPanel).Children[1] as TextBlock).Text;
}

However, data binding a list of objects to your ListBox.ItemsSource is a better solution than this.

Answer 2

了解情况的另一个途径是,你想要获得受你吨约束的物体的<代码>Name财产的价值。您可在上找到这个物体。

If you replace MyType with the type of your bound object, something like this should do what you want:

private void Click_B(object sender, RoutedEventArgs e)
{
    Button source = (Button)e.OriginalSource;
    string name = ((MyType)source.DataContext).Name;
}

Answer 3

也许有一个更好的解决办法,但如果你希望直接提及,你就只能走下路。

private void Click_B(object sender, RoutedEventArgs e)
{
     Button source = (Button)e.OriginalSource;
     StackPanel stp = source.Content as StackPanel;
     TextBlock blk = stp.Children[1];
     //Whatever you needed could now reference blk.Text
}
