提问by daewoosh
I have a form, which includes TextBlocks, Lables, Borders. And I want to be able to select text with the mouse like it would be some text in the table in MS Word or HTML table. And I can't use TextBox or RichTextBox instead. Is there a way to achive my goal?
我有一个表单，其中包括 TextBlocks、Lables、Borders。我希望能够用鼠标选择文本，就像在 MS Word 或 HTML 表格中选择表格中的一些文本一样。我不能使用 TextBox 或 RichTextBox 代替。有没有办法实现我的目标？
<Grid Margin="20">
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
</Grid.RowDefinitions>
<Border BorderBrush="Black" BorderThickness="1">
<StackPanel Orientation="Horizontal">
<TextBlock Text="some text in TextBlock" VerticalAlignment="Center"/>
<Label Content="another text in Label"/>
</StackPanel>
</Border>
<Border Grid.Row="1" BorderBrush="Black" BorderThickness="1">
<StackPanel Orientation="Horizontal">
<TextBlock Text="one more in TextBlock" VerticalAlignment="Center"/>
<Label Content="one more text in Label"/>

Use TextBox instead of a TextBlock, like the following code:
使用 TextBox 而不是 TextBlock，就像下面的代码：
<TextBox
Background="Transparent"
TextWrapping="Wrap"
Text="{Binding Desired, Mode=OneWay}"
IsReadOnly="True"
BorderThickness="0"/>
To make it cleaner, careate a template for the TextBlock and use the previous TextBox inside it.
为了使它更干净，请为 TextBlock 设计一个模板并在其中使用以前的 TextBox。

You can achieve it like this:
你可以这样实现：
<TextBlock Text="test2"
FontSize="16"
IsTextSelectionEnabled="true"
SelectionHighlightColor="Green"
x:Name="test"
Foreground="Black"
TextWrapping="Wrap"
TextAlignment="Left"/>
Just set IsTextSelectionEnabledto true.
You can also chagne color of selected text by changing SelectionHighlightColorproperty.
只需设置IsTextSelectionEnabled为true。您还可以通过更改SelectionHighlightColor属性来更改所选文本的颜色。
