WPF-TextBox中的文本无法选择？

Question

I am working on a project that dynamically loads text into a Text Box control. The problem is that, for some reason, the text does not seem as if it can be selected. I do not understand why as I thought that, by default, the text in a Text Box was selectable. Why is this and how can I fix it? Here is my XAML:

 <Window x:Name="viewWindow" x:Class="Games_Database.View"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="View" Height="300" Width="600" Loaded="windowLoad" ScrollViewer.HorizontalScrollBarVisibility="Visible">
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="77*"/>
        <RowDefinition Height="13*"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="57*"/>           
    </Grid.ColumnDefinitions>
    <ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" Width="550" Margin="21,5,21,10" Grid.RowSpan="2" IsManipulationEnabled="True">
        <TextBox x:Name="text" HorizontalAlignment="Center" Margin="5,0,0,0" TextWrapping="Wrap" VerticalAlignment="Center" IsHitTestVisible="False" Height="Auto" Width="500" Grid.RowSpan="2" ScrollViewer.CanContentScroll="True" FontSize="14" FontFamily="Times New Roman" IsInactiveSelectionHighlightEnabled="True" Text="" AutoWordSelection="True" />
    </ScrollViewer>
</Grid>

Any help would be greatly appreciated. Thanks much in advance!

Answer 1

The text cannot be selected because you have IsHitTestVisible="False" .

If you remove that attribute, the text box will once again be able to respond to mouse clicks from the user. Note that, with your current code, you can get the cursor inside the text box by pressing the tab key.

Answer 2

It's beacause you have IsHitTestVisible property set to false. Setting this property to false means that control will not respond on any mouse events. However you are still able to enter the control by using tab.
