In this post I have explain how to disable copy , cut and
paste using c# in asp.net without using java script.
Sometimes it is necessary to disable copy ,cut and paste
function for textbox in web page or website. It is basically used in re-inter
password or email account in registration page . So let’s do practically .
Open visual studion -> click on file -> open new
website -> click on empty website ->
gie a project name -> right
click on solution -> add new item -> click on web page -> click ok.
Drage a textbox on
design page and write the three main
command in textbox.
1.) oncopy="return false"
2.) oncut="return false"
3.) onpaste="return false"
Design you page like this:-
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" oncut="return false"
onpaste="return false" oncopy="return false" TextMode="MultiLine"
BackColor="#669999" Height="103px" Width="445px"></asp:TextBox>
</div>
</form>
</body>
</html>
