如何制作一个只读文本框，在点击时选择所有文本
本文关键字：文本 选择 一个 只读 何制作 | 更新日期: 2023-09-27 18:27:11
我正试图让一个文本框看起来像一个文本块（没有白色背景或任何东西），这样我就可以在其中显示结果文本和数字。当用户点击文本时，我希望整个结果突出显示，以便于复制/粘贴。这适用于Windows Phone 8应用程序。谢谢
我试过使用这个：
<Style x:Key="TransparentTextBoxStyle" TargetType="TextBox">
<Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilyNormal}"/>
<Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>

但它使所有东西都是黑色或不可见的，直到你点击文本来突出显示它。
要使其看起来像TextBlock，必须将IsReadOnly属性设置为true，并修改ReadOnly视觉状态的控件样式（模板），如下所示：

要选择焦点上的文本，请将以下事件处理程序分配给GotFocus事件：
private static void OnTextBoxFocused(object sender, RoutedEventArgs e)
{
((TextBox)sender).SelectAll();
}
我能够回答自己的问题。
风格：
<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>
文本框：
<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>
