c# - タップ時にすべてのテキストを選択する読み取り専用のテキスト ボックスを作成するにはどうすればよいですか?

Question

結果のテキストと数字を表示できるように、テキストボックスをテキストブロックのように見せようとしています(白い背景などはありません)。ユーザーがテキストをタップすると、簡単にコピー/貼り付けできるように結果全体が強調表示されます。これは、Windows Phone 8 アプリケーション用です。ありがとう！

私はこれを使ってみました：

                </ControlTemplate>

        </Setter>
    </Style>

ただし、テキストをタップして強調表示するまで、すべてが黒または非表示になります。

以下に示すように、プロパティを trueTextBlockに設定し、視覚状態のコントロール スタイル (テンプレート) を変更する必要があるように見せるには:IsReadOnlyReadOnly

フォーカスのあるテキストを選択するには、次のイベント ハンドラーをGotFocusイベントに割り当てます。

private static void OnTextBoxFocused(object sender, RoutedEventArgs e)
{
    ((TextBox)sender).SelectAll();
}

Answer 2

私は自分の質問に答えることができました。

スタイル：

<phone:PhoneApplicationPage.Resources>
    <Style x:Key="CopyPasteTextBox" TargetType="TextBox">
        <Setter Property="Foreground" Value="White" />
        <Setter Property="IsReadOnly" Value="True" />
        <Setter Property="TextWrapping" Value="Wrap" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate>
                    <Grid>
                        <ContentPresenter x:Name="ContentElement" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</phone:PhoneApplicationPage.Resources>

そしてテキストボックス：

<ScrollViewer VerticalScrollBarVisibility="Visible" Width="396" Margin="31,231,41,106">
            <TextBox TextAlignment="Left" 
                 FontSize="30" 
                 Margin="0,0,0,0"
                 Grid.Row="2" 
                 Foreground="White" 
                 Name="resultbox" 
                 Grid.ColumnSpan="2" 
                 BorderThickness="0" 
                 Style="{StaticResource CopyPasteTextBox}" 
                 GotFocus="resultbox_GotFocus"/>
        </ScrollViewer>
