how to disable copy, Paste and delete features on a textbox using C#

Question

Can anybody please suggest how to handle Cut,Copy and Paste events on a Text Box in WinForms using C#?

Answer 1

To prevent users to copy/paste using the keyboard set ShortcutsEnabled property to false. To prevent users to copy/paste from the context menu set ContextMenu property to new ContextMenu().

if (copyPasteEnabled) {
   textBox1.ShortcutsEnabled = true;
   textBox1.ContextMenu = null;
} else {
   textBox1.ShortcutsEnabled = false;
   textBox1.ContextMenu = new ContextMenu();
}
