MVC :: Multiple Instances Of Same Partial (with Same View Model) Messes Up Validation?
Jan 27, 2011
This project I'm working on have this custom clientside JavaScript validation framework created for (which I cannot change) that show error messages/summary based on your data annotations and a "Validate" method in your ViewModel.
Like I said I'm not allowed to change this, so wont be able to go with suggestions doing that.
What the person that created this did not foresee, is that one might need put several partials of the same type and having the same view model (each in a form) on a view.
So I went ahead and did things the normal way (using Html.whateverFor<model => model.whatever) and wala!....the custom validation thing throws error messages for the specific form fields, next to each form in the view. I was suggested to create a "prefix" for each instance of the view model, and do something like this:
Change: <%: Html.HiddenFor(model => model.AccountNumber)%>
To: <%: Html.Hidden(Model.ElementPrefix + "AccountNumber", Model.AccountNumber)%>
Not to mention the tons of jquery selectors and all that I have to go change (and all my view inputs)
(I just hate having to find workarounds for this "custom" everything they created for this project)

I have a Order view with 2 user controls in it.
The first user control in the view is just to validate the customer and get some more details about the customer. This control is having one text box (customer name) with the button. When the user clicks the button it should validate the customer name in the client side using data annotations of customer model. if validation success then it should use some bussiness logic to verify the customer and show the customer details on the form.
The 2nd user control in the view is to get the address of the customer by searching for the house no and the postcode. This control is having 2 text box with the button.
The first user control is based on the strongly typed customer entity
The 2nd user control is bsed on the strongly typed address entity
The view with both the user control is based on the strongly typed order entity.
The issue here is with the validation. I have the validation summary in the view and client sider validation is enabled. When i click the search button on the first user control the client validation starts and throws validation error messages because when i search for the customer at that point of time i will not have values to may of the customer related fields in the order view.
The same thing happen when i click the search button on the 2nd view. It will throw client side validation for other fields.
What i want to achive is that when the user click the search button on the user control 1 then the validation should happen only to the customer name field (both in client and server).
When the user click the search button on the 2 nd user control the the validation should happen only for houseno and the postcode both in client and the server.
When the user clicks the save button on the order view all the fields in the form even the controls usere input fields should get validated. How to achive this in mvc?

i am creating a MVC2 application for pubs and bars. I have a model 'Opening_Time' with the following properties:
int Day,time OpeningTimetime ClosingTimeWhen adding/editing an Opening_Time, I want to validate an Opening_Time, to check the user isn't adding one for an existing Day (ie they can't have two entries for the same day).
How/Where is the best place to do this?
Preferably, I want to do it a Model level, so I can use Model.IsValid and the Html.Form helpers

'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:

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).

<%@ 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">

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

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 have a partial view called experience that is basic html markup.
I have a page that contains rows of records (experience records) and one of the columns in these rows is an "edit" link column. When I click that link I want to pass the id of that row to a method that will package up the details of that row (linq query to the experience table using the passed in id).
(this is the important part) ...... I want the partial view (experience.ascx) along with its new Model containing the experience details to load in a modal dialog box rather than another page.

have been unable to find any explanation of this anywhere.I have an .ascx partial view that's pulling data from a given model.I want to populate a drop-down list in my partial view using data from a table
outside the model (it is in the same database and entity framework).I don't know the syntax (I'm pretty much just learning MVC2 and jquery), and don't even know where to start. I've gotten about as far as <% foreach step in [???] %>, but don't know what to do with it. What do I put in the "[???]"???

Basic flow would be: "Search" updates the "Search Result Listing", click on CRUD actions in listing would show partial view in "action".
how do I call to refresh the "Listing" after I do any add/update/delete without having user click search again?

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.

I'm using ASP.NET MVC 2 and here's the issue. My View Model looks something like this. It includes some fields which are edited by the user and others which are used for display purposes. Here's a simple version
public class MyModel
{
public decimal Price { get; set; } // for view purpose only
[Required(ErrorMessage="Name Required")]
[Code]....
But doing this, I get an error on UpdateModel(rec): The model of type 'MyModel' could not be updated.

I have a question regarding validation of drop-down list values. I have a view that is bound to a view model type called ReservationData.
This object contains a property CustomerVehicles of type List<VehicleData>. VehicleDatahas two int properties VehicleMakeId and VehicleModelId.
On my view I am trying to loop over the number of items in the CustomerVehicles collection and displaying two dropdowns for each, a vehicle make dropdown and a vehicle model dropdown usingDropDownListFor.
When I try to submit and validate I do not see any validation errors displayed on the screen.
Just in case you are wondering I have added a ValidationMessageFor for each dropdown as well. I am not sure if this is an issue with the structure of my view model and its complexity and how the controls need to be named or how the ids need to be set.
Here is the code for the looping over the collection:
