I have an ASP:TEXTBOX with the TEXTMODE property set to "Password".  I'm loading it with data in the Page_Load event from a SqlDataReader.  The SqlDataReader has data.  When the Page_Load event is fired, the textbox shows the value in plain text instead of showing asteriks (*).  I need to show the value of the textbox in * and not in plain text

Thanks in advance !!!

The ASP.NET server control is designed to work this way... in order to get around this you can use the standard input type=password, or assign the password to the textbox via code by adding attribute "value"

Here is an example from googe groups.

  Private Sub Page_Load _
  (ByVal sender As System.Object, _
  ByVal e As System.EventArgs) _
  Handles MyBase.Load
    TextBox1.Attributes.Add("value", "thePassword")
  End Sub

I totally agree with razo here. If you dont want to show it then why load it and try and display it as *'s

Thanks for the reply !!!

My requirement is as follows :-

I need to show the user the values for the textbox in *'s, so that an user can modify his password without any breach of security i.e., no other person standing or sitting behind or beside the user cannot be able to see as well including the user himself or herself.  The textbox should populate with the *'s instead of text.  

Rodnex the code mentioned by you is already done by me but was not able to show the values in *'s.  I cannot use <input type=password> since I am not supposed to use it.  This has to be done using <ASP:Textbox> control only.

Thanks in advance !!!!!

You are not showing the user any value in the textbox, all you want to show is *'s for each character. All that would do is let someone onlooking calculate how long that users password is. It is of no value showing *'s. The user can type in a new password without the textbox being populated with *'s.

If you want to show something in the textbox, why dont you just populate it with an arbitary number of *'s, its not like it makes any difference???

The only place Ive ever seen a password field pre-populated is in Windows. Even then its only an arbitary number of *'s, it doesnt do a direct display of 1 * for each character in the password.

If you *really* do need to show the password as *'s, do the translation through your code-behind and display a * for each character in that users password.
