I'm using Model-View-Presenter framework. When Loading a page, I'm having trouble setting the selected item that came from the Database.
In view, I know I need:
protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e)
{
presenter.DdlStatusSelectedIndexChanged();
// what should this pass?
}
Then in Presenter:
public void DdlStatusSelectedIndexChanged()
{
view.DdlStatus = ???
// Should I pass the SelectedIndex?
}
I also think that part of my problem is that DdlStatus I have as a List.
Interface:
List<StatusDTO> DdlStatus { set; get; }
The best I found is here (but needs formatted!) ---> [URL]

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; }
}
[code]...

I have been reading about different model for development
model view control mvc
model view presenter MVP
Model view view model MVVM
i belive MVC has two big Advantage over webform 1) TDD 2) More control on HTML
MVP is bit variation in mvc model. rapid development as well as 1) TDD 2) More control on HTML (correct me if i m wrong) see the below link

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 got a domain model as follows: (and my repository expect an instance of this object)
[Code]....
And a view model (which my views are based on)
[Code]....
At the moment I got it like this and have my controller action manually create a new Person object from the PersonModel object before passing it on to the repository, which does not feel right.
So I tried to have PersonModel inherit from Person and pass that to the repository (also tried casting the PersonModel to a Person object first), but that don't work out.
What's the right way to have PersonModel automatically cast to Person? I want to keep this logic as my current structure allow me to keep things really loosely coupled, with the repository layer not having a clue how it's being used.

I have an entity object as model input in my view. Not sure if it's the best approach, but I use the object references to get values from a related object.Let's say I've got a car entity and a manufacturer entity.Here's how it would look in my view
[Code]....
I've get a nullreferenceexception where the car entitity does not have a reference towards manufacturer. I'd like to output a " " if no manufacturer exists.

've created a Search partial view and it works, except for my view model. What i mean is, the partial view sends a string to my ActionResult Method, but only a string, that is not related to the view model that the partial view is built in. If i tell my ActionResult method to receive the view model in which the partial view is built in, it always tells me that i have null values. Here's my code This is my partial view:

one thing that has been puzzling me since learning MVC2 is the following case scenario: I have a view which contains two latest news lists, a login form and a signup form. Every example I found on Views and View Models so far has a one-to-one example such as a simple login form etc. But how do I create a model that provides the properties and validation for a login and signup form and manages the data for the news lists. can I pass multiple models in the strongly typed view? When I created one model the form validation would fail as it expects all fields - login and signup to be filled. I am missing some advanced examples or information.

making my first steps with asp.net mvc and I actually create a (very) small website.I have 1 controller : TasksController1 view : Tasks/Index.aspx1 Partial View : Tasks/AvailableSorting.ascx In my controller I have 2 methods :
[Code]....
In my Tasks/Index.aspx, I add my partial view (<% Html.RenderPartial("AvaliableSorting"); %>)
That sounds simple. But, It just doesn't work : the Index return a list of Task and the parial view (should) return a list of string.The index.aspx works perfectly, but the partial view doesn't get the right model ! he gets the model of the Index page (list of Task).

I am totally a new bee in asp.net mvc. Let me now explain my issue. I have a strongly typed view which inherits from a view model Document. I want to have a partial view in that view itself. My code for this purpose is :
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<HexsolveMVC.Models.Document>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
DetailsDocumentTemplate
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<div>
<div>

Published</div>
<h1>

I have an asp.net 2.0 web application that will run on the same web servers as SharePoint Server 2007. The application should run in its own App Pool (IIS 6.0). The Web Application needs to call the SharePoint Object model API.
Is there a resource that explains the required configuration / security settings and other considerations? It is possible that I need to make some settings in SharePoint Admin Console itself; aswell as config files. Script files might need to be located in a specific location in order to be accessible. Assemblies may need to be signed.
I can only get partial success running my Web application. But only if it is deployed to a Virtual Directory that resides under the SharePoint Website (in IIS & File system). Even with this setup, I JQuery / Javascript throw errors when accessed (object null); and also images not loading.
I have made some changes to the Web applicaton web.config file which have allowed me to run the application albeit the above mentioned issues with scripts and images (Virtual directory properties also set to allow scripts and executables to run). Ajax functionality appears to work OK.

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.

I am working with a model which has the following, basically a Project can have a score between -5 and 5 and I'd like to show a dropdownlist of the available options, i.e 5,4,3,2,1,0,-1,-2,-3,-4,-5.
[Required(ErrorMessage = "Score is required")]
[Range(-5, 5, ErrorMessage = "Score must be between -5 and 5")]
[DisplayName("Score")]
public double Value
{
get { return value; }
set { this.value = value; }
}
What would be the best way to accomplish this using a dropdown list and how can I make the score of 0 the
default selection?

I figured this wouldn't be too difficult to do, but I can't seem to figure out how to do it. Is there a way to easily access the current item from a ListView data source? For instance, you can easily evaluate the current item's properties using Eval("propertyName"), but is there a way to access the object itself?
And if this isn't possible, what I ultimately want to do is get the Type of the object.
