I can't invoke an action method via href

Gabor66 — Wed, 11 Nov 2009 01:28:38 GMT

In the sample appl. the ManageUser.aspx contains a list of user in a table. (p. 142). Every row contains a href link to the User/EditUser action, that picks up a memebership id parameter as querystring, and invokes the method with the parameter:

p. 143.

I tried to implement this code snippet in my own appl., but while this link is working in the TheBeerHouse application, doesn't in mine.

In my application the link invokes EditUser method without the user id.

Does anybody can explain me, what is missed in my application, that preclude the parameter pick up?

The delete action method is working, that uses the same user id.

I use the same web.config file.

Thanks

The forgot password doesn't work

Gabor66 — Thu, 05 Nov 2009 14:19:37 GMT

On p. 122. ForgotPassword action resets the password independently from the answer.

It seems likely, that Memebership.Provider.ResetPassword(username, secretAnswer) doesn't take into account the secret answer at all!

Does anybody else experienced this error, and can propose a solution.

What if the user forgot the username and password?

It would be better to get the e-mail address from the user instead of user name.

Thanks

Where can I download the latest version (2.1?) from

Gabor66 — Thu, 05 Nov 2009 07:34:42 GMT

I tried to find the download site of the latest version of the TheBeerHouse MVC, but found only the WebForm 3.5 version.

The development of the MVC version is terminated at all? I heard that the ver. 2.1 is the latest and test project is included. Anybody can me get some info?

Thanks in advance.

Html helpers doesn't work on site.master

Gabor66 — Wed, 04 Nov 2009 10:51:12 GMT

I try to create a new web application on the basis of the TheBeerHouse.

I imported the site.master, the user controller and views and related files from the content.

It is interesting, why in the register.aspx the html helpers work, but in the site.master doesn't.

What am I missed.

Thanks

DeleteShoppingCartItem error

ralphbethke — Tue, 03 Nov 2009 20:10:02 GMT

I get the following error in firefox.

[ArgumentException]: The parameters dictionary contains a null entry for parameter 'productId' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult DeleteShoppingCartItem(Int32)' in 'TheBeerHouse.Controllers.CommerceController'. To make a parameter optional its type should be either a reference type or a Nullable type.

It seems like it's looking for a dictionary pair???
This is similar to DeleteShippingMethod, except that works.
I'm at my wit...................s end.

Bug on demo site

The live demo site at www.thebeerhouseexample.com causes a server error when you try to make a forum post. If I ignore the post and reload the page, I can see the post. The one I made is "Which Becks is Best?". Please advise. Thanks.

New version, older technology?

Gabor66 — Thu, 29 Oct 2009 06:54:50 GMT

Hi,

I'm a bit confused, when the new book "ASP.NET 3.5 Website Programming: Problem - Design - Solution" released, because it seems, a lot of new features included in the project, that uses the outdated ASP.net webform technology instead of MVC.

So wich technology to use? I think, that MVC has many advanteges:

-better organization of the project,
-easily testable

but because of the lack of the MVC controls yet, maybe less productive, but this is a temporary issue.

Because we are before starting a new project, wich technology to use?

Any opinion will be greatly appreciated.

Thanks

Gabriel
