Hi,
You can write the code as follows,
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script language="javascript">
var txtBoxClientId = "<%= txtBox.ClientID.ToString()%>";
function Check(a)
{
if (a.checked == true)
document.getElementById(txtBoxClientId).disabled = false;
else
document.getElementById(txtBoxClientId).disabled = true;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtBox" runat="server"></asp:TextBox>
<asp:CheckBox ID="chkBox" runat="server" Checked="true"/>
</div>
</form>
</body>
</html>
in the codebehind file write as follows in the pageload event,
protected void Page_Load(object sender, EventArgs e)
{
chkBox.Attributes.Add("onclick", "Check(this);");
}
