Hi,
Using login control in my login.aspx page . when ever user checks "Remember me"  userId is stored in cokkie.
At Next login, userID is filled automatically.
This works fine....

Now i'm trying to do the same ..for teh password .... by storing password in cookie and at next login ...fill the password ...
BUt, i am getting this error when i'm trying to fill the Login.Password filed using ...
Login2.Password = Server.HtmlEncode(Request.Cookies["pwd"].Value);
Error:- Property or indexer 'System.Web.UI.WebControls.Login.Password' cannot be assigned to -- it is read only

can i accomplish what i need?

First off, it's a bad idea to store passwords in cookies.  But if you are dead set on doing this, you can access the password textbox by using FindControl, then set the text property of that TextBox.

Login login = (Login)MyLoginView.FindControl("LoginUser");

if (login != null)
    TextBox passwordTextBox = (TextBox)login.FindControl("Password");

if (passwordTextBox != null)
    passwordTextBox.Text = "mypassword"

Hi Nash 2334,

Though there is no error, password is not loaded automatically. Although userid is.

When i tried to debugg using the break points , under control Login2 -> Login2.Pawword  ="" & Login2.UserName = "username"

even though i'm using this line...
                TextBox mypassword = (TextBox)Login2.FindControl("Password");
               mypassword.Text = Server.HtmlEncode(Request.Cookies["pwd"].Value);
NO LUCK sir...

Sorry, use Attributes.Add:

mypassword.Attributes.Add("value", Request.Cookies["pwd"].Value);

You can use the FormsAuthentication encrypt method.  Good MSDN article here, very straightforward:

Good luck.
