ASPNet Membership Controls

[Rory Becker]

Hi All

I have a database which has it's own set of tables for users etc

I already successfully use the Login control by handling the Authenticate
event and checking the suitable values against my own DB.

Now I need to use the ChangePassword control but I cannot stop the system
from trying to create a database.

I would implement my own membershipprovi der but that really seems like a
lot of work.

Is there a way customising the ChangePassword control so it calls my code
to check if the change is valid and to actually perform the change?

Many thanks in advance

Create a custom membership provider rather than kludging all of the events.
Through a custom provider, you can tailor all of the processes to use your
table structure instead of the one MS provides.

Thanks for Gregory for the informative inputs on custom membership
providers.

Hi Rory,

If you just want to reuse the ChangePassword control without involving the
membership provider layer, I think you should register the
"ChangingPasswo rd" event and put your own changing code there. Also, make
sure you call "e.Cancel=t rue" in that event so that it code logic won't go
further to the built-in control's code logic( that's why you see it always
create thet default sqlexpress database).

For example:

=============== ========
protected void ChangePassword1 _ChangingPasswo rd(object sender,
LoginCancelEven tArgs e)
{
e.Cancel = true;

//your own password changing code logic here.

Response.Write( "<br/>Old Password: " +
ChangePassword1 .CurrentPasswor d);

Response.Write( "<br/>New Password: " + ChangePassword1 .NewPassword);
}
=============== ======

BTW, it is also possible that you create a custom control which derive from
the ChangePassword control. I have checked the ChangePassword control's
code in reflector, you can simply override the following code which is the
one that control the postback processing logic:

===
protected override bool OnBubbleEvent(o bject source, EventArgs e)
{
..............

==========

You can do your own work such as (call your own function that changing
password ) in this event

Hello Cowboy (Gregory A. Beamer),

Create a custom membership provider rather than kludging all of the
events. Through a custom provider, you can tailor all of the processes
to use your table structure instead of the one MS provides.

Here are a couple of links:
http://www.devx.com/asp/Article/29256

http://msdn.microsoft.com/en-us/library/f1kyba5e.aspx
and one video
http://www.asp.net/Learn/videos/video-189.aspx

Those are some great links. Thanks very much.

I also found this post "http://davidhayden.com/blog/dave/archive/2007/10/11/CreateCustomMem bershipProvider ASPNETWebsiteSe curity.aspx"
in which David hayden points out that you do not need to implement every
method and can in fact throw NotImplementedE xceptions for all others.

I finally created a Custom MembseshipProvi der as you suggested

The only methods I needed to implement were 'Initialize', 'GetUser', 'ChangePassword '
and 'ValidateUser'.

I also overrode al the properties but supplied only backing fields for these
and initialised all of these to suitable default values.

I reduced the 1200(approx) line file suggested in the video you linked to,
to (approx) 200 lines.

I'm sure I will need to implement more for some of the other controls that
I might want to use later on but this was fantastic.

Thanks very much

Hello Steven Cheng [MSFT],

Thanks Steven, this makes a great deal of sense.

I have recently discovered (as indicated in my reply to Cowboy) that the
implementation of a MembershipProvi der need not be as complicated as I thought
an so have gone in this direction instead.

I am curious however, from a theoretical standpoint... If I were to take
your suggestion and cancel the further processing within the ChangingPasswor d
event, how then would I get the control to visually react to the success
or failure of my attempt to change the password?

Thanks again for your help

Thanks for your reply Rory,

Yes, per your scenario, since you won't have much time to implement a
complete new membershp provider, simply intercepting the login control's
event and do your own code logic will be better.

For your new question. Yes, since you cancel the event, the built-in
behavior of LoginControl will not continue as normal. However, based on my
understanding, those LoginControl won't do much more for sucessful or
failure result. Therefore, I think you can also add your own code logic to
display the result. For example, put a label to display successful or
failure condition. How do you think?

Sincerely,

Steven Cheng
