QuestionPassword Field Padding with Question Marks (?s) Pin

Hello,

The strangest thing is happening and I can't track down the source of the issue. I have a form where users can edit their profile. On the form there is a password field. Here is the code:
<asp:textbox id="txtPassword" textmode="Password" runat="server" size="30">

In the SQL database I store the password as a binary, so the UPDATE statement looks as follows:
UPDATE Account SET Password=CONVERT(BINARY,'" & Replace(txtPassword.Text, "'", "''") & "') WHERE AccountID=15

When I retrieve the data, the SQL code looks like this:
SELECT CONVERT(VARCHAR,Password) FROM Account WHERE AccountID=15

Finally, when I pass the password to the text field, the code looks like:
txtPassword.Attributes.Add("value", dsResults.Tables(0).Rows(iRowLoop).Item(5))

I have used this code hundreds of times without any issues, however, for some reason the password in the form is being converted to the password plus a bunch of question marks to fill the remaining space. My password field is size 30, so if your password is "ketchup" then this gets placed in the password field:
ketchup???????????????????????

I looked at the value in the database and there is nothing padded on the end of the value. It seems that something really weird is happening on this line:
txtPassword.Attributes.Add("value", dsResults.Tables(0).Rows(iRowLoop).Item(5))

I am at a loss and am sure I am just overlooking something very simple. I even looked at another site of mine where I have this same pattern and everything looks identical...no clue where I am going wrong.

Thanks in advance for your help!

Frank
