Hi Matt,
If I get you correctly then are pointing towards that if you have BL or service layer then you would do away with Model? Correct me if I'm wrong.
But, please note that model is the manifestation of your view i.e. it is tightly coupled to your view. You should have that as well as Business layer where you would get the data (from DAL), do some processing and then pass the data onto the model. Also, note that model does not do away DTO as well which would be used to communicate between your various layers. A lot of the time DTO and models are pretty much the same but can differ based on the requirements.

Thank you, Rohit. But no, I know the model is necessary. What I'm referring to is: are data annotation attributes used for validation (like "[Required]") irrelevant when using a service layer?

But, Matt data annotations are for validations on the view side and nothing to do with your BL/service layer. Basically in MVC, models are responsible data validations.
I would still do the required validations on my BL/service side (required, null, etc.)

How do annotations pass through serialisation (JSON)?
Caveat: I am even less knowledgeable about MVC!
MVC, being server based can have the DAL/Models etc in the same project, eliminating the service component. I don't like that design and will need to look at a service component so this is relevant to me.
So the service would supply data based on the Table/View structure from the database via json and the MVC would then deserialise them into UI models.
This to me reduces the benefits of using EF spit as the DAL as it is bloody useless in a service.

Sounds like a permission issue.

No one can possibly know exactly what the issue is based on the tiny amount of information you provided.

Hi,
I am using Visual Studio 2010, VB.NET, my site has .NET 4, using Web Forms. I have a page with, among other things, two asp:ImageButton controls, each in its own little AJAX UpdatePanel. This page has been working since some time in 2013. One button is Add To Wishlist, the other Add To Cart. Both have an OnClick event and they are nearly identical, with the exception of the purpose and SQL Server stored procedure they call. As I said, they've both been working for quite a while. I made no changes to the page. Yet, suddenly, the Add to Cart button does not work...nothing happens, no error is thrown, it just doesn't do anything. the Add to Wishlist button still works as before. When they are updated, the image is changed. Add to Cart image is changed to "In Cart", Add to Wishlist is changed to "In Wishlist".
I've seen some complaints about ImageButtons not working in the latest IE, but this is in Firefox as well as IE.
I don't understand why one works and the other doesn't, and why it happened when no changes were made to the page.
My site is on a shared hosting plan at web.com, so there are many things that I cannot do. I only have access to certain things on the server.
Could a change they made cause this? But still, one button still works, same page, nearly the same exact code.
there are actually two pages, one is for pay items, one is for freebies. Both use the same code, and the Add to Cart button is not working on either page...both were working until recently.
I thought that perhaps the page was corrupted, so I re-uploaded the pay item page and cycled the application (I at least can do that), but it made no difference.
Help!

Can you clarify if it is the process that fails or just the change of image. IE is the record written to the cart table is SQL.

Nothing at all happens. It is as though I clicked on a word of text on the page. Nothing happens. The code in the OnClick event never fires, the data is not written, the image doesn't change.

Try using IE 9+ and pressing F12, then the bug button and run the page, see if an error is generated.
|

Thanks.
It actually did:
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0
Unknown error, code 0. Really helpful. 
The wishlist button does not throw this error.

Yes, I did:
Protected Sub btnAddToCart_Click(sender As Object, e As System.Web.UI.ImageClickEventArgs)
And the Add to Wishlist button:
Protected Sub btnAddToWishlList_Click(sender As Object, e As System.Web.UI.ImageClickEventArgs)

You may have a response.write in the code somewhere that runs in the update panel
|
|
|
|
|
Nope. And as I said in the original post, it was working since 2013, and the page wasn't changed. It just suddenly started this recently. The button is the only thing in the update panel.

I am going to try this again, with a screen capture. After several attempts to fix this, I reverted to the original code and now I am getting an error in Visual Studio (this error wasn't there before).
OK, there seems to be no way to add an image to my post. that's kind of useless.
The error message is:
'btnAddToCart' is not a member of 'Danas3D_MarketplaceProduct'.
But it most certainly is. I am extremely confused about this. The other ImageButton is in the same kind of container, with one exception...I have removed the AJAX UpdatePanel that was wrapped around the btnAddToCart.
Please, someone must have seen this behavior at one time or another. I tried Build Page thinking it would update something. The error is in the code behind, in:
Protected Sub btnAddToCart_Click(sender As Object, e As System.Web.UI.ImageClickEventArgs)
The line is:
oAddToCartBtn = Me.btnAddToCart
Please! This is driving me nuts! It makes no sense!

Why are you posting this in the ASP.NET forum and not the Article Writing[^] forum?
|
|
|
|

Wrong forum, and i checked your Link[^] , it is working fine only.
So much complexity in software comes from trying to make one thing do two things.

Hello
If I have this in the tags of my Site.master file:
<div class="navbar-collapse collapse">
<!--<ul class="nav navbar-nav">
<li><a runat="server" href="~/">Home</a></li>
<li><a runat="server" href="~/About">About</a></li>
<li><a runat="server" href="~/Contact">Contact</a></li>
</ul>-->
<asp:LoginView runat="server" ViewStateMode="Disabled">
<AnonymousTemplate>
<ul class="nav navbar-nav navbar-right">
<li><a runat="server" href="~/Account/Register">Register</a></li>
<li><a runat="server" href="~/Account/Login">Log in</a></li>
</ul>
..............
and this in the tags:
<link rel="stylesheet" type="text/css" href="logon.css">
Why can't my vb.net project see the logon.css file that I created:
.nav a:link { color: #ffffff; text-decoration: none; }
.nav a:hover { color: #ffffff; text-decoration: underline !important; }
and which appears in Solution Explorer (please see screenshot).
Basically, I am trying to change the colour of two links, 'Register' and 'Log on', to white.
Thank you.
