MVC :: Validating Objects Within ViewModel - Get Data From Three Tables And Display Them In 1 View

Apr 2, 2011

In my application, I need to get data from three tables and display them in 1 view. I have created a .dbml and created a ViewModel in my Models folder to deal with this. Here is my ViewModel:

[Code]....

My web application uses the Default ASP.NET Membership. So User [ u ] is of type aspnet_Users from the default Membership. This ViewModel allows all the CRUD opertation to be carried out. However on the Create and Update operations, I would LOVE some Model Validations, My question is:

1) Would the User [ u ] default validation kick into place in my ViewModel ? Cause I know by default ASP.NET Membership, has Model Validation.

2) For table SUserDetails (which I have created myself, not part of default) how do I add ViewModel validation to it for when someone does an Update or Create?

Display Data From Multiple Tables In A Single MVC View?

Nov 30, 2010

I am having a hard time solving the following with an MVC view. My goal is to display data from multiple tables in a single MVC view. The bulk of the data comes from a table called Retailers. I also have another table called RetailerCategories which stores the retailerid from the Retailers table and also a categoryid linking to a Category table. Note that there are multiple records for each retailerid in the RetailerCategories table.

In the view I want to show a list of retailers and with each retailer I want to show the list of categories applicable to them. What would be the best way to accomplish this?

C# - Is It Possible To Map Multiple DTO Objects To A Single ViewModel Using Automapper

Jan 24, 2010

I was wondering if it is possible to map multiple DTO objects to a single ViewModel object using Automapper?

Essentially, I have multiple DTO objects and would like to display information from each on a single screen in ASP.NET MVC 2.0. To do so I would like to flatten the DTO objects (or parts of them...) into the Viewmodel and pass said viewmodel to the view. If I had one DTO this would be easy, but I've never seen it being done with multiple. Obviously there are a number of roundabout ways to do this (outside of automapper), but this is the approach that I would like to take if possible.

This seems to work fine. My question to you good folks: Is there a correct way to do this? I tried following the making a custom model binder per the blog link I posted above but it didn't work (there was an issue with reflection, the code expected certain properties to exist) and I needed to get something going ASAP. PS - I tried to cleanup the code to hide specific information, so beware I may have hosed something up.

I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there.

Does 1 ViewModel Really Have 1 View

Feb 16, 2010

its said that 1 ViewModel has 1 View. 1 View is for me a UserControl. What if my UserControl has different areas filled with data from different entities, do I have then several Views and need to build several ViewModels? e.g: I display in a UserControl 3 entities: customer(listbox),order(datagrid),product(datagrid). Each of those "data areas" has add+remove buttons and textboxes to enter data.

Actually each of those "data areas" are put in its own GRID having so the posibility to set a individual datacontext.

1.) Should I now create 3 ViewModels CustomerVM,OrderVM and ProductVM?
2.) Are those 3 "data areas" seen as an own sort of separated View, although I have not put them in 3 UserControls.xaml files ???
3.) When this one UserControl is inside a TabControl`s tabpage where do I load the 3 entities related data? Inside the MainViewModel? I want to show/load that data only when the user clicks the tabheader.

C# - How To Post Form From View Strongly Typed To ViewModel?

Mar 31, 2011

I have a view model as such:

public class MyViewModel
{
public MyObject myObject{ get; set; }
public List<MyList> myList{ get; set; }
}

I have a view with a form strongly typed to MyViewModel This view allows you to enter values for the properties of MyObject, as well as create a list of MyList objects. The List part works fine although I thought that would be the more difficult of the two. Assuming MyObject has a property Description I create a textbox to enter the value as such:

@Html.EditorFor(x => x.myObject.Description);
The text box renders with an id of MyObject_Description...The problem is when I post this to my controller action, MyObject does not get bound at all(althought the list items do as they recieve the appropriate IDs of "MyViewModel_MyList[guid].myListValue")
What am I doing wrong here??
EDIT: more info
The first line of the view is:
@model MyApp.ViewModels.MyViewModel
And the Action method:
[HttpPost]
public ActionResult Create(MyViewModel myViewModel)
{
}
I am passing a new MyViewModel into the partial view to begin...
public ActionResult Create()
{
MyViewModel model = new MyViewModel();
return PartialView(model);
}
EDIT 2
Ok When I render my partial view that contains the forms I call :
@{Html.RenderAction("Create", "MyController");}
this is called from within a View of type @model IEnumerable<MyApp.Models.MyObject>
(this view displays a list of currently existing MyOjects, and at the bottom the partial is rendered to allow the user to add another MyObject to the DB)

Viewmodel - Mvc Strongly Typed View Model With Multiselect

Jan 5, 2010

I would like to know how i can bind my form values to my strongly typed view from a MultiSelect box. Obviously when the form submits the multi-select box will submit a delittemered string of my values selected...what is the best way to convert this string of values back into a list of objects to attach to my model to be updated?

public class MyViewModel {
public List<Genre> GenreList {get; set;}
public List<string> Genres { get; set; }
}

When updating my model inside the controller i am using UpdateModel like below:
Account accountToUpdate = userSession.GetCurrentUser();
UpdateModel(accountToUpdate);

However i need to somehow get the values from the string back into objects. I beleive it may have something to do with model-binders but i can't find any good clear examples of how to do this.

MVC :: Create Two Objects On Separate Tables Using One POST?

Jan 13, 2010

I'm trying to achieve something very similar to a forum. Two basic tables in a database, [Thread] and [Comment] (one to many relationship).

I need to create a form using MVC that creates the initial Thread, and also the very first comment row in the [Comment] table, which references that topic.

Would I need to create a custom object for the View Model? Is there any examples anybody knows of that demonstrate what i'm trying to achieve as I can't seem to find information..

The Model-Repository-Service-Validator-View-ViewModel-Controller Design Pattern

Jan 19, 2010

When I first heard about ASP.NET MVC, I was thinking that would mean applications with three parts: model, view, and controller.

Then I read NerdDinner and learned the ways of repositories and view-models. Next, I read this tutorial and soon became sold on the virtues of a service layer. Finally, I read the Fluent Validation documentation, and I'll be darned if I didn't end up writing a bunch of validators.

Tonight, I took a step back and thought about what had become of my project. It seems to have become the victim of the design pattern equivalent of "feature creep". Somehow I'd gone from Model-View-Controller to Model-Repository-Service-Validator-View-ViewModel-Controller. You want loosely coupled and DRY? We got your loosely coupled and DRY right here! But I'm wondering if this could be a case of too much of a good thing.

Am I right to be concerned? Or is this actually not as crazy as it sounds? On one hand, it seems crazy to have so many layers. On the other hand, every layer has a clearly defined purpose that makes sense to me. Have your MVC applications turned into MRSVVVMC apps too? If not, what do they look like? Where's that right balance?

Make A SQL View Showing Data From 3 Tables Like Crosstab

Nov 18, 2010

I'm using ASP.net membership system with SQL Server 2000 database. What I want to do is create a view (or stored proc if that's better) which will return a table with the following columns:

UserName | Role1 | Role2 | Role3 | .... | Role*N*

Where the columns (besides Username) are generated to include all the ASP.net Roles in the application.I need this to be generic (i.e. when I add a new Role, I want the procedure/view to compensate and list that new Role as a new column). I want the values in the Role fields to be 1 (True) or 0 (false) if a user in in that role. I can make a table that has such columns using Dynamic SQL to create the variable number of columns, but I cannot seem to populate them.

How can I accomplish this?Tables involved are shown below:

CREATE TABLE [dbo].[aspnet_Users](
[ApplicationId] [uniqueidentifier] NOT NULL,
[UserId] [uniqueidentifier] NOT NULL, [code]....

Combine Data From Multiple Tables Into One View Model

Dec 5, 2010

I'm fairly new to all this, but have slowly been teaching myself C# and ASP.net MVC over the past year or so...I really tried to search for this, but haven't been able to find anything - it may be I'm using the wrong terminology!I'm using ASP.NET MVC2 with EF4 connected to a SQL Express db. Situation: Without getting into too much specifics, I have one table called 'Plan.' Under 'Plan' are several different categories that are related to a single Plan item [say Category A, Category B, Category C and Category D]. Each 'Category X' table has a beginDate, endDate and other details specific to that category.

I'd like to be able to create a summary page that combines all items from Category A, Category B, Category C, and Category D and sorts by beginDate - but only need a few of the columns [eg - begin/end date, name, id].

MVC :: Select Data And Display It From Two Tables?

Mar 28, 2011

I really have no idea what i am doing here, but all I want to do is display a one to many list from two tables in the database in a view.

I have a ChartController with the following code:

public ActionResult ChartCategoryOne()
{
var chart = from e
in db.PTP_Exercise

[Code]....

Now I need a view. The view that VS2010 creates via the PTP_AthleteExerciseResult model looks like just what I need. But I get the following error:

The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery`1[PersonalTrainerPro.Models.PTP_Exercise]',
but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[PersonalTrainerPro.Models.PTP_AthleteExerciseResult]'.

I'm not sure why it is passing PersonalTrainerPro.Models.PTP_Exercise, which is one of my automatically generated models derived from the database in the edmx and I have no idea how to set it up to pass IEnumerable instead of DbQuery. I actually have no idea what it means or even if I'm heading in the right direction.
