嗨亲爱的，如果你使用TextBox控件作为用户名和密码，你可以按照这个。受保护 void btn_Click（ object sender，EventArgs e）
{
// GetValues（）;
HttpCookie cookie = new HttpCookie（ UserName）;
cookie.Values.Add（ this .userName.Text， this .password.Text） ;
Response.Cookies.Add（cookie）;
}
这里有一些javascript代码
< pre>函数readTheCookie（）{
var the_cookie = document 跨度> .cookie;
if （the_cookie！= ）{
document .getElementById（' <％= password.ClientID％>'）。value = the_cookie.split（' ='）[ 2 ];
}
}

Hi, everyone
i Need solution for the following concept in ASP.Net
When the user types username and password with the "Remember ME" checkbox checked it will stored the username and password in the cookie inside the system.
Whenever the user logins again, when username is entered in the textbox the password must be automatically loaded from the cookie. simultaneously the cookie must store multiple username and passwords.
Here is the code for
CS.aspx

Thanks in advance....
Try this:
Remember me next time in login control in asp.net[^]

Hi Dear if you are using TextBox controls for username and password you can follow this.protected void btn_Click(object sender, EventArgs e) { //GetValues(); HttpCookie cookie = new HttpCookie("UserName"); cookie.Values.Add(this.userName.Text, this.password.Text); Response.Cookies.Add(cookie); }
here is some javascript code<pre>function readTheCookie() { var the_cookie = document.cookie; if (the_cookie != "") { document.getElementById('<%=password.ClientID %>').value = the_cookie.split('=')[2]; } }
[Removed begging for vote]
Thanks
Good Luck
