MVC :: Using "Model" To Display Page Data?
Jan 12, 2011
have my aspx page where I have a Model that has the data to display on the page. My question is, I am trying to make a link but the href="" is not working for me. Is there something else I can do?Here is that part from my page, the part that I am talking about is the "href='<%: linkItem.LinkUrl %>' does not work for me.
<% foreach (UrsWeb.Model.LinkGroup linkGroup in Model.LinkGroups) { %>
<div><%: linkGroup.LinkGroupTitle %></div>
<div>

I am a MVC newbie & am lost in various ways validation can be implemented in my application.
I created a custom model-level data annotation validator attribute, but am unable to display its error message in the view. Basically, I have let's say 5 properties in the Entity class Job (model-level custom attribute called UniqueKeywords defined on it):
1) LoginID: value comes in the URL
2) Title: Required property level attribute defined on it
3) CatID1, CatID2, CatID3 - 3 categoryIDs - these are dropdowns in the view with same list of keywords in all 3.
I want to mandate that the values picked by the user in all 3 category dropdowns should be different.
With reference to the code pasted below, here is the explanation of what happens:
When I submit the form without specifying a title or picking anything from any of the 3 category dropdowns, the validation occurs for the property level Required attribute as well as model level uniquekeywords attribute, but the error is displayed only next to the required field "Title". I can confirm that the custom validation also works by filling in some text in the Title field & then re-posting the form...this re-displays the view, but the error message "Category cannot be duplicated" is not displayed.
Only relevant code sections are pasted below:

I've got a view model that has some text properties. And I use Html.DisplayFor to display them on the screen. But those text data won't be post back, so in the case of failed validation, the returned view won't have those data. How do I handle this kind of situation?

I have one view page (MyView.aspx) and many data sources to bind on this page. Lets say it has Books, Publishers, Comments, etc. Each one of those has an object which provides a List, List, etc. In my view, what are my optiosn for multilple model biding? I want to check to see if each one is empty, and then enumerate it. But I can't check Model.Count() because wouldn't Model be made of all those objects if I set the page to inheriet from? What are my options? Should I load each content area in a control/partial view? Or can I just dump each object into ViewData and then check the count by casting in the view?

I've been used to decorating data model classes with data annotation attributes, but the purist in me baulks slightly at including purely presentational attributes such as display format here. I am, however, quite happy to keep validation centric attributes here. One good reason I have to continue keeping all annotations etc. in the data model is that my view model aggregates data model classes, e.g.
my ViewModelBase.DetailItem<TEntity> property in the view model is just a reference to an entity class in my data model. If I wanted to move presentational annotations to the view model, I would have to quite radically revise my design to one where I duplicate data model properties in my view model and use an object mapping tool to populate view model objects based on data model objects.

Say I have a Form model which contains a list of Field objects loaded from a database. Each field object has a type that defines whether it is a listbox, combobox, input or textarea.
What would be the best way for displaying the Field objects correctly? I was thinking in my View using a switch statement and calling a specific partial depending on the case.
[Code]....
Is this a valid approach? What other methods would people recommend to do this?

but I am new with MVC and database-driven applications.
I hava a table with Cities (ID,Name) and one with Businesses(ID,CityID,Name). The later has a foreign key relationship with the first table.
I used a linq-to-SQL class to create my models.
My problem is that I need to access the City Name(not the ID) when displaying the Business Model View.
How can I do this? if from my controller I call the View passing the auto-generated Business Model, I only have access to the ID.

Normally I work in ASP Classic, and am still a bit green on ASP.Net MVC.
I have my model with its fields or entities (might not be the right word hence why not able to find if previously answered, forgive me), and some of these will have null values such as hyperlinks, email address, specific types of phone numbers, etc.
What I want to do is not write certain blocks of HTML within the foreach loop if a field is empty.
In ASP Classic, I would have written an If statement along the lines of:
<% If RS.field <> NULL then %>HTML with <%=RS.field %><% End If %>
<% If RS.field2 <> NULL then %>HTML with <%=RS.field2 %><% End If %>
...
However, I don't know how to achieve the same result in ASP.Net MVC.In one of my current usages, a list of sellers returned for a specific set of search results, it runs through a foreach loop and returns the current HTML (in part):
Website: <a class="url" href="<%= seller.ContactWebsite %>" target="_blank" title="Visit the website for <%= seller.Name %>"><%= seller.ContactWebsite %></a><br />
So, if for example I have a field from the model, say seller.ContactWebsite, and this field was NULL, I would not want it to write this as part of the foreach loop.

I wanted to know peoples thoughts on ways of achieving the following:
1.I have a products page which is in a datalist.When i click the page how can i get the page data to display in a new page with all product details so customers can see everything about the product
2.Also i currently have an upload facility which allows admin users to upload products with descriptions and other info.But i have to add a colours option.My problem is how can i store this information for the product as there may be several colours available for the product.Would i have to create fields for different colours in the products table?
also how could i attach images for each colours when selected from dropdown? e.g when customer selects blue colour it will display the image attached to the blue product?

I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.
When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?

I made a few changes to the DB in SQL server management studio then right clicked on the .edmx doc to get it to update. That seemed to work fine but when i compiled the app everything that referenced the EF seems to be broken.The Error list now contains the below error for all classes that used it.
The type or namespace name '' could not be found (are you missing a using directive or an assembly reference?)

I have an issue of static variable in an asp.net application. Let's say I have a server with 8 CPUs running windows 2008 R2 hosting an asp.net webbsite, nothing fancy here, no funny configuration.
Is the following statement true? at any single time, there's one and only one process is running and accepting requests, even in the recycling stage. The reason I am asking is: I have a static field in my class, and I want to make that's the only static instance in the website. I've heard in some circumstances, IIS is recylcing your application, and it will start a new process, but the old process is still working, thus I will have 2 static instances in memory, which defeat the purpose of static field.
One step further, let's assume there might be 2 instances in memory, can I assume there are at most 2 instances at any single time? And can I assume once the second instance is up, the first instance will NEVER accept new requests?
Another question: Recently I have a problem with an applicationdomain concept. Looks like if an application domain causes a memory leak, unload the domain will not release the memory (Umanaged leak). So to what extent Application Domain is isolated?

I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted
<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>
This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });
This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }
But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.

I am having an issue with something that seems like it should be simple. I am just trying to use the sharepoint object model from an ASP.net page. It's running on Framework 3.5 (required by sharepoint), and I realize it needs to be set to build on x64 (also required by sharepoint from what I understand). The issue is when I do this it returns "Could not load file or assemply ". If I switch it to any CPU then it reports that the call to build SPSite can't find the site address.
Basically if I open a brand new web app project and switch it to framework 3.5 and build target x64 it will report this same error. It seems like I am doing something stupid but I have no idea what it could be.

I have a web page that I am developing in ASP.NET MVC. I have one page that is being opened to allow the user to edit some data. I have the data stored in a couple of tables, and when there is a "trip", the user needs to add the data for that trip. I first add the record to the table, and then have them edit that record. However, when my edit view comes up, it is dropping off the model.id and the page shows that the Id is required.
I am also using Fluent NHibernate, and have verified that the record is created, and has a value for Id.
