Disable copy paste in textbox

[D i x y]

Hello, how to disbale copy paste from and to textbox programatically

[Christian Graus]

You may be able to do this by catching the keystrokes and rejecting them. I don't think there's a paste event. You would probably need to reset the clipboard after a CTRL-Insert or CTRL-C, b/c it's probably already done.

Christian Graus Please read this if you don't understand the answer I've given you "also I don't think "TranslateOneToTwoBillion OneHundredAndFortySevenMillion FourHundredAndEightyThreeThousand SixHundredAndFortySeven()" is a very good choice for a function name" - SpacixOne ( offering help to someone who really needed it ) ( spaces added for the benefit of people running at < 1280x1024 )

hey you might be able to "catch" the event of(ctrl + c) and (ctrl + v) and not handle it... that might do the trick Hav fun

Like this: private void textBox1_KeyDown(object sender, KeyEventArgs e) { if(e.Control && e.KeyCode == Keys.C) { e.SuppressKeyPress = true; } else if(e.Control && e.KeyCode == Keys.V) { e.SuppressKeyPress = true; } }

private void textBox1_KeyDown(object sender, KeyEventArgs e) { if(e.Control && e.KeyCode == Keys.C) { e.SuppressKeyPress = true; } else if(e.Control && e.KeyCode == Keys.V) { e.SuppressKeyPress = true; } } this is good, but i do't want to this code paste in all control. i want this code type only one time

Do you mean you want this code to execute only once? If yes then just unbind it using this.textBox1.KeyDown -= new KeyEventHandler(this.textBox1_KeyDown);

Aside from the fact he probably shouldn't have just posted up this code as an instant solution (requiring the OP to do nothing for himself), the code only needs to be written once, you can bind one event to multiple controls.

What if the user copies or pasties using context menu of the textbox?

Just reinitialize the context menu of the textbox during form load without any items in it.

I actually found a bug, where you can still get the context menu even when you do that. If i remember right, to get the context menu to STILL appear, you right-click the text box and hold the button down - move you mouse off of the text box - and then release the button. Then the normal menu appears :confused:

Thanks for find. How about handling this in WndProc method then?
