I want to set an <asp:textbox> TextMode property to Password but also populate it with characters(so the user doesn't have to re-enter their password).
If I set the TextMode property to Password at design time and then try and set the Text property on my Page Load event, no characters appear.
If I try and set the TextMode property after setting the Text property, no characters appear:

txtPassword.Text = GetPassword()
txtPassword.TextMode = TextBoxMode.Password

When I do a watch(in debug) on the Text property the password does show up but it is not displayed(with the '*' character) on the page.

Any ideas would be greatly appreciated

Thanks
paul

Do this...In your Page_Load,

txtPassword.Attributes.Add("value", GetPassword().ToString())

While the response Greg gave will work, if a user does a view source on
the form, the password is visible as plain text and that is never good
from a security standpoint.

Rather, I would use Viewstate to hold the password value and if the user
doesn't change it then retrieve the value from view state.

In the page load event
ViewState["OrigPassword"] = userpassword.toString();

Password.Attributes.Add("value","**********")

In the postback (however you are doing it)

If(Password.Text != "**********")
ViewState["OrigPassword"] = Password.Text;

Then use the view state value in your update.

Hope this helps.

What I have done is encrypt the password at INSERT time into the database,
then if the user views the source he/she will only view an encrypted
password anyway. This is also more secure in the sense that if someone gets
access to the users table they will still only see encrypted passwords, and
will this not be able to manipulate the system as easy.
