c# - How can I remove the default "Paste" context menu entry of a TextBox control in a Windows 10 UWP app?

Question

I am building a small UWP app in C#, to scan EAN barcodes and assigning descriptions to it.

The default action when I click on my textboxes is to start speech recognition. And I want the textbox to go into manual editing mode, when I rightclick it (long tap on touch-devices).

Therefore I'd like to remove the default context-menu for my TextBox control. I know how to do this in Windows Forms applications (just add an empty TextBox.ContextMenu with visibility=Collapsed).

Can somebody here help me please, and tell me how to remove the default "Paste" context menu (or "flyout") entry from my textboxes? Is this even possible?

您可以禁用 TextBox 的上下文菜单，ContextMenuOpening 事件将为您提供帮助。下面是整个代码。

XAML:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <TextBox x:Name="textBox" Text="test" Height="80" Width="100"  ContextMenuOpening="TextBox_ContextMenuOpening" />
</Grid>

C#:
 private void TextBox_ContextMenuOpening(object sender, ContextMenuEventArgs e)
 {
       e.Handled = true;
 }
