Question

I’m writting a Windows Phone App, in the GUI a have a listbox with many buttons, something like 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>

I need to obtain the content of the TextBlock “txtblockUrl” when I click on the Button, how can I obtain this value ?

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

        }

Answer 1

You can walk down the layout hierarchy as shown below

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.
