how can i have a default value such as "password" string for textbox below (with asterisks) :

                    <asp:TextBox ID="headertxtPassWord" runat="server" Text="password" CssClass="header-login-input" ValidationGroup="A"
                        TextMode="Password"></asp:TextBox>  

Answer 1

In codebehind, you can do this:

headertxtPassWord.Attributes.Add("value", "ThePassword");

Use this to set the value, instead of setting the Text property. You can still read the value from the control via the Text property.

Answer 2

Ok I think I did not understand you correctly.

Here you can find the answer with some background and explanation Basically the point is that MS prevents showing default password from security reasons and this should be done in code behind to avoid unveiling password to others.

Hope this will help.
