i am working on MVC 2.0 , i would like to use gridview and list view as i am trying to display the product page for a shopping cart solution.
can i use them if yes then how and if not what could be the alternative solution to display product with shopping cart button and how can i pass parameter to display product when somebody click on the product view more detail.
I need to pass a list of Entity Objects from Controller to View but not put it in the Model context. It is the users homepage, but I am putting a list of alerts on the users home page(somewhat like facebook). So I need the User Context as the Model I pass but need to pass the Alert model as well so I can show the list of alerts.. How would I do that? The code below is what I have so far..
UserController

UserRepository

when I'm building a menu in a view I get following error when code reaches <% Next item%> :
System.InvalidOperationException was unhandled by user code
Message=The value of a property that is part of an object's key does not match the corresponding property value stored in the ObjectContext. This can occur if properties that are part of the key return inconsistent or incorrect values or if DetectChanges
is not called after changes are made to a property that is part of the key.
Source=System.Data.Entity
My view: (its a userview)
[Code]....
My Model
[Code]....
My Datasource

I use this way of looping frequent the only thing is that this is that this entity has a view as source and not a table, so I think it has to be related with that.
I'm having troubles remembering how to grab the list view's state, or page, so that when you leave the list, you can return to the list view page you left on. I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).
View 1 RepliesI have a dropdown list within a details view that allows me to set 1 or many categories to a perticular record(in this case a photo). The select command in this case only displays those catetegories that are not already attached to the selected photo.
all works well and as you select a category and add it to the database the category is removed from the dropdown list and is added to a gridview which shows all categories that photo is stored with.
My Problem is that when i delete the category from the gridview the dropdown list does not delete with said deleted item unless i do a "click in URL bar and press enter" to totally refresh the page.....
how to refresh the dropdown list in the details view after the gridview item has been deleted?

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

I am using a strongly-typed view to display a list of products, where every li-element gets a unique id:
<ul id="product-list">
<% foreach (var item in Model.Products)
{ %>
<li <%= "id="product_" + item.Id + """ %> >
<div class="item">
<%= item.Name %>
</div>
</li>
<% } %>
</ul>
Now I want to attach to the click-event of every single li-element, so that if the user clicks on a div-element, detailed product-informationen should be loaded asynchronously into a details-pane. I know how I can use jQuery to invoke an action-method ajax-style and also how to display the json-result which contains the product-details, BUT I have no idea, how I could attach the onclick-event to every single div, so that I can use the productId to load the details.
When I am creating Strongly Typed View I get lots of Classes in View Data Drop down. Classes like Automapper, ninject, Interface..., latebound... Due this its very hard to find my project classes. Is there any way to restrict dropdown to only display my project classes?

Let's say we have a entity to add - an Invoice with multiple Lines
public class Lines
{
public string ObjectName;
public string Color;
}
public class Invoice
{
public string DocumentID;
public DateTime InvoiceDate;
public List<Lines> lines;
public string Observation;
}
The Lines is valid if and only if it has ObjectName and Color
Now, when in AddMode , the requirements are to show enter a new Invoice with 10 Lines by default .
This was easy (binding to an object that contains list, right?) - but in validation mode, the ModelState.IsValid is validating all my 10 lines - regardless if the user have been entered only 2 lines.
I have tried to remove the empty lines by writing a Binder for Invoice, inheriting from DefaultModelBinder and removing the empty lines ( those for ObjectName AND Color both nulls or empty ) .But, no matter what overriding method (CreateModel , BindModel ) I have used , no success. The binding model occurs first.
I have tried to do ModelState.Clear() and ValidateModel(invoice) in the controller. But ValidateModel is not validating "sub-properties of complex properties" - see comments from
[URL]
If you know how to either :
a) re-validate all properties (including for complex object)
b) modifying the model before ModelState grab errors
c) ?

I want to create a view that draws from mutiple sources of data and creates a 'summary' view.This would include:An author (data source A) A list of the authors latest writings (data source B) A list of topics the author writes about (data source A)I notice I cannot pass into ...return View(author, articles, topics) from the controller.It seems you have to pick one.I want to construct my View from multiple partial views for each type.Not sure I am trying to do this the correct way.

View 7 RepliesI have an EditTask View for editing the following properties for a Task that I am modeling.
[Task Name]
[Project Name]
[Assigned Employee]
Task Name and Project Name are just simple text boxes.
I want Assigned Employee to be a selection from all the available Employee's currently in the database. Dropdownlist is not really an ideal option because there could be hundreds if not more possible employees.
I'm thinking a link to show a select employee grid listing in either a popup or another page where filtering can take place (b/c employee has other properties such as Dept) and the selection is made and the EditTask view is updated would be ideal but not sure. I'm new to ASP.NET MVC so I'm a little lost on where to start to implement this.
What is the best way to handle this UI scenario in ASP.net MVC?
I'm trying to keep track of employees in my database. I have two tables, Employees and Departments. The Employees table contains a foreign key relationship with Departments through a column named DepartmentID.
Here's my entity:
[code]....
I have a page that contains a form to add an employee. I'm passing the entity to my view page, and calling <%: Html.EditorForModel() %>
The problem is that the view creates a textbox for the DepartmentID.
How can I force the view to display a dropdown for DepartmentID that contains all the Departments in my database as the dropdown's list items? Is there a way to do this by just adding a metadata attribute to the property in my entity?
I have a dropdown list on an ASP.NET MVC project that I am pretty sure is not binding to my model because of my nhibernate mapping. I have tried many variations on the asp mvc side resulting in this post here.
MVC side of things seems fine I believe the issue may be that my object is trying to bind, but my mapping is out of whack.
My mapping is:
<many-to-one name="Project" lazy="false"
class="AgileThought.ERP.Domain.Property.Project"
column="ProjectGUID" />
My View gives an error saying that the GUID from the dropdownList selected value is not valid. Which I think may be that it is trying to push the GUID into my related project object.
The value 'fd38c877-706f-431d-b624-1269184eeeb5' is invalid.
My related project list binds to the dropdown list just fine, it is just not binding to my models Project entity.
EDIT: This question is vague and will likely be of little use to anyone. I am awarding internet monies to the gentleman below whom "helped" me.Sorry that the title is a little vague. I am still new to asp mvc & EF. Here is my issue. I have a DB somewhat like this.
Employee
- ID
- Name
- Address
EmployeeJob
- EmployeeID
- JobID
- StartDate
JobTypes
- ID
- JobName
I want a create form that will show all the Employee fields as well as a list of JobTypes for the users to be able to select. Then I will post the results back to the controller and update the DB. I have started looking into custom viewmodels, but am still unsure of exactly how to put that together and get it to work.
I have a list on the page & I'm trying to add it a dropdown list to narrow down the results

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.
Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.
ASSET CONTROLLER:

I have tried many of the posts that refer to setting up drop down lists but can't set them up in the content because this is a List View.
I want to bind a field in a View to a property in a ViewModel. The object is "Program" and has the properties "Name" and "Level". So the user should be able to set the name of a program and the level of experience he/she has with this program.Program is a table in an Sql Server database, and is accessed through Entity Framework. So it would be easy enough to bind the Level property in the ViewModel to a textbox:
@Html.TextBoxFor(model => model.Level)
But I want a dropdownlist with a limited number of levels (1-5). So how do I do this and still have the dropdownlist bind to the ViewModel property?
I've been at this same question in different forms now for a while (see e.g. Entity Framework and MVC 3: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. ), and it's still bugging me, so I thought I'd put it a little more generically:
You have an entity object (using Entity Framework), say User. The User has some simple properties such as FirstName, LastName, etc. But it also has some object property lists, take the proverbial example Emails, to make this simple. Email is often designed as a list of objects so that you can add to that object properties like Address and Type (Home, Work, etc). I'm using this as an example to keep it generic, but it could be anything, the point is, you want the user to be able to add an arbitrary number of these items. You should also be able to delete items (old address, or whatever).
Now, in a normal web page you would expect to be able to add these items in the same View. But MVC as it seems designed only makes it easy to do this if you call up an entirely new View just to add the address. (In the template for an Index View you get the "Create New" link e.g.).
I've come across a couple of examples that do something close to what I mean here:

and

The problem is, although the sample projects on these sites work fine, with mock model objects, and simply lists (not an object with a child list), it's a different thing if you actually want to do something with the posted information - in my case save to database through the Entity Framework model. To adapt these cases to that, all of a sudden I'm in a maze of intricate and definitely not DRY code... Juggling objects with AutoMapper and whatnot, and the Entity Framework won't let you save and so on (see above link if you're interested in the details).
What I want to get at is, is it really possible that this is such an uncommon thing to want to do? Update a child collection in the same View as the parent object (such as the email addresses in this case)? It seems to me it can't be uncommon at all, and there must be a standard way of handling this sort of scenario, and I'm just missing it (and no one here so far has been able to point me to a straighforward solution, perhaps because I made it too abstract with my own application examples).
I'm using Entity Framework for my object-relational mapping, and jqGrid for my grid.
I have an Employee entity, that contains a ContactID field. I have a Contact entity that contains fields FirstName and LastName.
I want to display a list of Employees in a grid, and give the user the ability to sort by FirstName and LastName.
Here's what I have right now:
public JsonResult GridData(string sidx, string sord, int page, int rows)
{
var pageIndex = Convert.ToInt32(page) - 1;
var pageSize = rows;
var totalRecords = GetAllEmployees().Count();
var totalPages = (int)Math.Ceiling(totalRecords / (float)pageSize);
IQueryable<Employee> employees = GetAllEmployees().
OrderBy(sidx + " " + sord).
Skip(pageIndex * pageSize).
Take(pageSize).ToArray();
}
As you can see, this only gives me the ability to sort by fields in the Employee entity, so I can't sort by FirstName and LastName.
How can I modify this to accomplish that?
When adding a stored procedure into the Entity Data Model I can select whether the procedure returns a scalar, a (new) complex type or one of the entity types I already defined.I mean assuming I have a view like this
CREATE VIEW FilteredFoos as SELECT Foo.* FROM Foo join ... WHERE ...(that is a view that implements some involved filtering, but returns all columns from one table) how do I add it to the project so that I can use the entity set, but get the Foo objects, not some new FilteredFoo objects.
var foos = myDB.FilteredFoos.Include("Bar").ToList();
foreach (Foo foo in foos) { ...
I have an EDM, it includes the entities extension and history. My goal is to use history to keep track of all the changes made to extension entity. For example, if extension with ID 223 has its property 'Name_Display' changed - I want the history entity to record this.
I'm using ASP.NET with VB.NET. Where in my code do I put the hook to say, "update the history entity" and what should that hook look like?
How do you delete more than one entity at the same time in the designer Entities list. it seems that the designer interface only allows the selection of 1 entity at a time....
