Sir,

I created website using asp.net with c#.Design and Source Coding is as

follows.

Design

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtUserName" runat="server"></asp:TextBox>
</div>
<div>
<asp:TextBox ID="txtPassword" runat="server" TextMode="Password" AutoCompleteType="DisplayName"></asp:TextBox>
</div>
<div>
<asp:CheckBox ID="chk" runat="server" />
</div>
<div>
<asp:Button ID="btnLogin" runat="server" Text="Login" onclick="btnLogin_Click" />
</div>
</form>
</body>
</html>

Source Coding

public partial class WebForm1 : System.Web.UI.Page
{
HttpCookie myCookie = new HttpCookie("yourInfo");
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.Cookies["UName"] != null)
txtUserName.Text = Request.Cookies["UName"].Value;
if (Request.Cookies["PWD"] != null)
txtPassword.Attributes.Add("value",Request.Cookies["PWD"].Value);
}
}

protected void btnLogin_Click(object sender, EventArgs e)
{
if (chk.Checked == true)
{
Response.Cookies["UName"].Value = txtUserName.Text;
Response.Cookies["PWD"].Value = txtPassword.Text;
Response.Cookies["UName"].Expires = DateTime.Now.AddMonths(2);
Response.Cookies["PWD"].Expires = DateTime.Now.AddMonths(2);
}
else
{
Response.Cookies["UName"].Expires = DateTime.Now.AddMonths(-1);
Response.Cookies["PWD"].Expires = DateTime.Now.AddMonths(-1);
}
}
}

i stored username and password in cookie as follows.

username - Ram

password - ram

username - Mahesh

password - mahesh

i typed username as Ram in txtUserName.

when i focus on txtPassword, ram should be filled automatically in txtPassword.

i need coding in asp.net using c# for this concept.

its urgent.

send me immediately.

Thanks in advance.

You can use Javascipt to set password to password textbox.
"onblur" event of username textbox set the cookies.


<script language="Javascript">
function getCookieValue(CookieName)
{
var iCount,varCookiesName,y;
var  arrCoo =document.cookie.split(";")

for (iCount=0; iCount<arrCoo.length; iCount++)
{
  varCookiesName=arrCoo[iCount].substr(0,arrCoo[iCount].indexOf("="));
  y=arrCoo[iCount].substr(arrCoo[iCount].indexOf("=")+1);
  varCookiesName=varCookiesName.replace(/^\s+|\s+$/g,"");
  if (varCookiesName == CookieName)
    {
       //set return value to Password TextBox
       document.getElementById("txtPass").value = unescape(y);
    }
  }
}
</script>

//call above javascript function on "onblur" event of Username Textbox
<asp:TextBox id="txtUserName" runat="Server" onblur="return  setCookieValue()">

hope it helps

Thanks

use login controls.that login control have username,password field, remember password, u just check the user info(Login_authenticate Event) and set the cookies. loginname control is used to display the username.and that is help to develop the forms based authentication system.
