MVC :: Pass More Than One Entity Into A View?

Feb 3, 2011

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.

MVC :: Error In View While Looping Trough IQueryable(of T) Entity From A SQL View?

Jan 18, 2011

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
[Code]....

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.

C# - How To Pass Model From A View To A Partial View

May 5, 2010

I have a view that is not strongly typed. However I have in this view a partial view that is strongly typed.How do I do I pass the model to this strongly typed view?I tried something like

public ActionResult Test()
{
MyData = new Data();
MyData.One = 1;
return View("Test",MyData)
}

In my TestView

<% Html.RenderPartial("PartialView",Model); %>

This give me a stackoverflow exception. So I am not sure how to pass it on. Of course I don't want to make the test view strongly typed if possible as what happens if I had like 10 strongly typed partial views in that view I would need like some sort of wrapper.

Entity Selection In View Without Using Dropdownlist?

Aug 31, 2010

I 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?

Creating A View And Updating An Entity Model?

Mar 13, 2011

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.

Adding And Removing Items Dynamically In One View With Entity Framework And MVC

Mar 1, 2011

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:

[URL]

and

[URL]

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).

ADO.NET :: Entity Data Model And Database View Returning The Same Columns As There Are In A Table?

Aug 19, 2010

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();

DataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?

Oct 18, 2010

I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):

Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub

And here's the markup for the datasource:

<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">
</asp:ObjectDataSource>

My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:

Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function

When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?

How To Retrieve A Subset Of Data From Entity Object Data Source And Pass To Another Page/

Oct 8, 2010

I am playing about just now trying to teach myself a little bit about the entity framework. I have a Gridview data bound to a Entity Date Source using the Entity Framework. If I select certain items in that list I then wish to redirect another page and populate another gridview with just the items selected (but with more detail, different includes/navigation properties)

This is probably the most simple thing but I have spent 2 hours banging my head on the wall trying to get this to work. Essentially I have a continue button which when clicked should identify all the UIDs (a column in the gridview) of the rows and allow me to subset to just these rows and pass them to another page to be rebound to another datagrid
