This code will disable cut/copy and paste options( Ctrl+X,Ctrl+C and Ctrl+V) through keys.
C#
private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Control == true)
            {
                MessageBox.Show("Cut/Copy and Paste Options are disabled");
            }
        }

For disabling right click on your textbox:

Put a blank contextmenuestrip on your form and rename it for ex: mycontext, then set the Contextmenuestrip property of your text box in mycontext. User will not be able right click on your textbox.

For disabling copy and paste put this code on KeyDown Event handler of your textbox


C#
private void textBox1_KeyDown(object sender, KeyEventArgs e)
  {
   if (e.Modifiers == Keys.Control)
   {
     e.Handled = true;
    textBox1.SelectionLength = 0;
   }
  }

Good answer! 5!
Private Sub TxtPassword_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs)
           If e.Control And e.KeyCode = Key.V Then
               e.Handled = True
               e.SuppressKeyPress = True
           End If
           If e.Control And e.KeyCode = Key.C Then
               e.Handled = True
               e.SuppressKeyPress = True
           End If
       End Sub

Code was needed in C# (not in VB.NET) and that too in 2012. However, appreciate your efforts :)

~ Happy Coding
Friend, please find the code for same also use the true block to generate your custom event.

C#
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Control && e.KeyValue == 86)
    {
        e.Handled = true;
        e.SuppressKeyPress = true;

    }
}



please vote if this solution is accepted or relevant for you.

Thanks,
Ambesha
