Disable Copy Paste Right Click Using JavaScript In Asp.Net TextBox

In this example i'm explaining how to Disable Copy Paste Right Click Using JavaScript In Asp.Net TextBox, Some time for many reasons we don't want to allow users to use right click to copy paste or by using ctrl+C , ctrl+v in textbox on a aspx page in asp.net, To disable this we can use javascript

we can achieve this in 2 ways

1. use this method when u don't want any alerts or message

<asp:TextBox ID="TextBox1" runat="server"
oncopy="return false"
onpaste="return false"
oncut="return false">
</asp:TextBox>


2. If you want to show alerts than use this method instead
Right this javascript function in the head section of aspx page, in this function we are disabling right mouse click and ctrl keys
<head runat="server">
<title>Untitled Page</title>
<script language="javascript">
function DisableRightClick(event)
{
//For mouse right click 
if (event.button==2)
{
alert("Right Clicking not allowed!");
}
}
function DisableCtrlKey(e)
{
var code = (document.all) ? event.keyCode:e.which;
var message = "Ctrl key functionality is disabled!";
// look for CTRL key press
if (parseInt(code)==17)
{
alert(message);
window.event.returnValue = false;
}
}
</script>
</head>

Now use this function on the textbox which we want to disable copy paste and right clicking
<body>
<form id="form1" runat="server">
<div>
<strong>
Right click disabled</strong> textbox
<br />
<asp:TextBox ID="TextBoxCopy" runat="server"
onMouseDown="DisableRightClick(event)">
</asp:TextBox><br />
<br />
<strong>Ctrl key </strong>disabled<br />
<asp:TextBox ID="TextBox2" runat="server"
onKeyDown="return DisableCtrlKey(event)">
</asp:TextBox><br />
<br />

Another method to disable<strong> Cut,Copy and paste
</strong>in textbox<br />
<br />
<asp:TextBox ID="TextBox1" runat="server"
oncopy="return false"
onpaste="return false"
oncut="return false">
</asp:TextBox>
</form>
</body>
Hope this helps
