让WPF文本剪切，复制和粘贴限制 [英] Make WPF textbox as cut, copy and paste restricted

问题描述

我怎样才能让一个WPF文本剪切，复制和粘贴限制？

How can I make a WPF textbox cut, copy and paste restricted?

推荐答案

剪切，复制和粘贴是常见的命令中使用任何应用程序，

Cut, Copy and Paste are the common commands used any application,

<TextBox CommandManager.PreviewExecuted="textBox_PreviewExecuted"
         ContextMenu="{x:Null}" />

在上面的文本框代码中，我们可以限制命令管理类

in above textbox code we can restrict these commands in PrviewExecuted event of CommandManager Class

和在后面的代码添加下面的代码，你的任务完成了。

and in code behind add below code and your job is done

private void textBox_PreviewExecuted(object sender, ExecutedRoutedEventArgs e)
{
     if (e.Command == ApplicationCommands.Copy ||
         e.Command == ApplicationCommands.Cut  || 
         e.Command == ApplicationCommands.Paste)
     {
          e.Handled = true;
     }
}
