How to update a collection of objects in a view model?

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :ASP.Net
I have been trying to design a form, which uses a view model that contains an object array. I want to set up this form so that when the submit button is clicked, all the members of the array are updated. Here is my code:The class definition of the array element:public partial class luSubject    {        public string Name { get; set; }        public bool FilledName { get; set; }public in MasterSubjectId{get;set;}        public luSubject()        {            FilledName = true;        }    }This is the view model I used for the form:public class TestModel    {        public luSubjects[] Subjects;        public int[] MS { get; set; }        public SelectList sl { get; set; }        public TestModel()        {            Subjects = new luSubjects[3];            for (int i = 0; i < Subjects.Length; i++)     &n

Model View Controller (MVC) for ASP.NET

Model View Controller (MVC) architectures, immediately wonder how the MVC pattern can be applied in an ASP.NET world. This article will demonstrate how the MVC pattern can be applied to an ASP.NET web application and still maintain the basic Microsoft supplied architecture.

The Model-View-ViewModel (MVVM) design pattern describes a popular approach for building Windows Presentation Foundation or Microsoft Silverlight applications. Robert McCarter shows you how the ViewModel works, and discuss some benefits and issues involved in implementing a ViewModel in your code.

Entity Data Model and database view returning the same columns as there are in a table


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. 

How do I do something similar for a view?

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) { ...

Thanks, Jenda

Executing Command Logic in a View Model

Through the use of the Windows Presentation Foundation's (WPF) advanced data-binding capabilities, the logical structure of a user interface can relatively easily be disconnected from its presentation. Bindable components can now contain nearly all of an application's user interface logic and in most circumstances, replace the need for controller objects from the classic Model-View-Controller (MVC) pattern. So it's no wonder that a new pattern for UI design has appeared

Can you have a different input and output model in a view?

So here is what I would like to do. Lets say I have a view that can do multiple things, and thus talk to several different controllers. For example, it might create a new group, or change the name of an existing group, or add a user to some group. Now, for the view to display correctly, it would only need the username, a list of groups, and possibly a list of users. Yet for the controllers to work they would need a different set of information, the userid to be added to a group, the name of a new group, or the name and id of a group to edit.With this setup, there would be a potential of several different models for both input to the view, and output to the different controllers. I like the idea of using the helpers Html.Textboxfor() ect. to create the different submission elements, but I don't so much like the idea of having one giant model (Even if it just a model that inherits or has several sub models) that gets passed around everywhere for this view. It seems... clunky.Perhaps there is a better way to do this (if so, feel free to smacking me around with a few "Your and idiot"s) but is there any way to have a separate input and output model for a view?

SSRS Subscription Management: Restart, Stop, View Status, update properties, etc

As SSRS admins, there are times when a user comes to us and ask: I didn't get my reported emailed to me today?or worst, a report subscription going to multiple people doesn't run and now you have lots of people missing their subscription - (suppose server crashed, or something happened).One idea of course would be to have the subscription owner re-schedule it to run now, or create a new -- but - i'm thinking - we should create a subscription adminstration tool.a .net app that queries the ssrs web service, gets a list of subscriptions in the ssrs system (or perhaps by folder) and then is able to 'restart a subscription', "stop a running one", 'view all subscription status, schedule, owner, etc' if I wanted to d this - what is the web service that I could use this for?and most importanly - has anybody dont anything like this that they can share?this is for ssrs 2005 & and I'm hoping 2008 can be called through the same .net app tool

Passing objects between View and Controller

 I would like to pass List<SelectListItem> (not selected item but the whole "List" object) back to controller.for example in my GET controller i would have thisViewData["list"] = some select list from repository;then on post I would like to get the list back from view..pretty much i'm trying to use ViewData["list"] as storage..this way I would use ajax to remove or add items to/from the list.what's the best approach ?thanks
