Disable Copy/Paste in a Textbox in Your WinForms Application

The following two steps disable the Copy/Paste feature in a textbox:
  1. Disable the default menu and associate the textbox with an empty context menu that has no menu items (mouse actions).
  2. The user can still use the shortcut keys on the keyboard and perform these operations. So, override the ProcessCmdKey method as shown below:
    
       // Constants
       private const Keys CopyKeys = Keys.Control | Keys.C;
       private const Keys PasteKeys = Keys.Control | Keys.V;
    
      protected override bool ProcessCmdKey(ref Message msg, Keys   keyData) 
      { 
       if((keyData == CopyKeys) || (keyData ==   PasteKeys)){
               return true; }
         else{
            return base.ProcessCmdKey(ref msg, keyData);}
      } 
    
Note: Return true, which supresses the base class functionality.
