MVC :: Partial View Not Sending View Model To ActionResult Method?

Dec 29, 2010

'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:

MVC :: Model Folder - Partial Class And DataContext Class Are Not Communicationg?

Nov 26, 2009

I've created a one table contact DB, which has only 3 columns (Id, Name, and Phone). I've then created the ContactsDataContext using my table Contacts in the model folder. Finally, I create a partial class still in the model folder (public partial class Contact).now when I write this

public partial class Contact{ public string MyContact { get { string name = this.Name ?? String.Empty; } // ... Other lines omitted }}
I get the following error :"'ContactsManager.Models.Contact' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'ContactsManager.Models.Contact'
could be found (are you missing a using directive or an assembly reference?)"Is something wrong??? Even the Intellisense in not showing the properties from my DataContext class. Yet, I've written some partial classes in the past with no problem.

MVC :: View And Partial View Sharing The Same ViewData.Model?

May 3, 2010

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).

Web Forms :: Return Focus To A Method After Calling Method In Another Class?

Aug 28, 2009

I have a c# method that basically says

myMethod{
//refresh data
myDataGrid.DataBind();
//write out data to excel
myOtherclass.ExportToXL(myDataGrid)
//mark records as exported
embeded sql function
//refresh datagrid
myDataGrid.DataBind();
}

The problem is when I call the function of the other class (myOtherClass...) focus never retuns back to myMethod, and my embeded sql function, or the second databind never gets called.

Is there somehting like a 'Try { } Finally{ }' where the finally gets exicuted regardless of loss of focus?

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.

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)

MVC :: Calling Business Logic In Model From Submit Tag In View?

Jun 30, 2010

Currently I am working on a project at work that deals with MVC. I have never used MVC before, only dealt a little with ASP with VB, and that's it. I've dabbled in HTML but not much. I don't currently have the money for a book, so I'm using this forum. So there's a lot of jargon I may not pick up on or may ask a lot of questions, so please bare with me.Anyways here's what I would like to do, or understand. We're using ASP.NET Membership Security (not sure if that's what it's actually called) for passwords and accounts. My issue is that I've been working on other projects while the rest of my team has been working on this, so they know more about it than I do. And I don't want to take too long to understand it, but I have to find the best way to make sure the following doesn't happen:

1) When changing a password, it can't be within the last 10 passwords used for that user.2) When creating/changing a password, it cannot have dictionary words, names, phone numbers or personal data within it.3) The password must be a minimum of 16 characters.Number 3 is rather easy and completed I believe. However, 1 and 2 prove tenuous. We want to store the previous passwords hashed and we were going to save the salt used. However, I'm beginning to think that with the Membership class you can't specify the salt to hash a password. Is there a way to de-hash a password? We do not want to store the passwords as plaintext, so that is out of the question.I believe the best order (for 1 and 2) is to do 2 first (before it's hashed) and then 1. For two, I need to know how to call a function in the Model code from a <submit> tag in the View code. I've done a little research online but thought I'd ask and see if it gets answered while I'm looking for the answer.

In general, my questions are:1) How do I call a function in the ****Model.cs from a <submit> tag in the *******.aspx?2) What's the best way to compare previous passwords that are hashed? 3) If I know the salt, can I de-hash a password? (I believe the answer to this is no.)4) Can I specify the salt to hash a password? (I believe the answer to this is no.)5) If #3 and #4 are no, then should I do encryption instead of hashing?Details: MVC2, C#, Membership.

MVC :: HtmlHelper Extension Method V Partial View?

Jan 18, 2011

I would like to know what the pros and cons are of creating an extension method v a partial view. From my understanding, htmlHelper extension methods are better as they enable one to unit test the view.

e.g. Assert.AreEqual(Html.Price(), "<td><tr><td>Price</td><td>4.50</td></tr>");

where the Price() method contains the presentation logic.

Since both the extension method and partial view are reusable, what then is the point / benefit of a partial view?

MVC :: NullReferenceException In Model Class On Strongly-typed View

Jun 16, 2009

I created a LINQ to SQL class named Store that references a table Stores with id, servingArea as the properties. I added my controller then used the VWD GUI to Add a new strongly typed View and chose my Model which is JBBO.Models.Store and used the LIST option I also noticed in my view that it has Inherits="System.Web.Mvc.ViewPage" %> My problem is everytime I access the view, I get a NullReferenceException with the error: "Object reference not set to an instance of an object" This is on the "Model" of foreach (var item in Model) of the code it generated. I am able to fix the error by passing in the Model directly via my controller return View(new StoreDataContext().Stores); However, this seems like an extra step, and I can't find any mention of this in the tutorials. Am I supposed to be able to simply return View() and let the Inherit on the PAGE do the work?

MVC :: Store Model In Separate Class Library- Pass Model Objects?

May 19, 2010

I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.

When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?

Default Model Binder Does Not Bind Model Class

Dec 28, 2010

I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted

<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>

This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });

This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }

But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.
