MVC :: How To Populate Form Fields Without Strongly Typing Model

Sep 28, 2010

I am facing few issues. I am using MVC2.I am developing a form which is being created dynamically based on its layout and all html attributes info stored in DB table. This dynamically generated form stores data(this table have all html field names as columns) in another db table(db is mysql).

I have created ViewModel class in which i get both design table entity objects and data table entity object. I, then, created strongly typed view based on that ViewModel. But the problem is when i rendering html fields using html helpers i.e

TextBox(Model.tblDesign.htmlField_name).it doesnt bind with the columns of Model.tblData whose names are same as of Model.tblDesign.htmlField_name. how can i bind fields of data table?

MVC :: Strongly Typing View To Custom Type?

Dec 31, 2010

I am integrating asp.net mvc with an existing asp.net web form application. All works well until I try and inherit my view from custom type.

[Code]....

Reference has been added to the assembly containing the above namespace to the web form project. I had manually create an aspx page since the mvc view templates are not available in web forms project. I guess the way view gets bound to the object by telling it where to inherit from or does asp.net mvc performs some hidden plumbing. There weird part was that I could not even bind it to IList<string>.

Url Variables To Populate Form Fields And/or Auto Submit

Nov 12, 2010

I have a shortcut on my desktop to a login page for a website I use quite often. Every time I go there I have to reenter my user name and password.

The desktop URL shortcut I have is

http://domain.com/service/Login.aspx

I've tried adding the following changes

http://domain.com/service/Login.aspx?username=ckimball&password=joshua1

But this doesn't auto populate the fields on the website when it loads. Is there something special I need to do so the webpage will fill in the fields on the form?

Also bonus if I could just auto submit to login so I don't need the page to load and have me click "login" but I don't think that's possible... or is it?

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 :: Razor: Strongly Typed View With Model Containing Collection Properties?

Jan 4, 2011

Note: I'm working with MVC3 RC and Razor views.I've got this model:

[Code]....

I want to have a strongly typed create view for this model, that allows you to insert 1 to many addresses and phone numbers as part of the view. Ideally, the Action is strongly typed as well:

[Code]....

What would this view look like to facilitate creating 1 to many Addresses and PhoneNumbers, as well as having the state re-created correctly if the ModelState fails when posting? I've tried a number of variations including EditorTemplates and can't figure out how to do this.

C# - How To Access Attributes Of Properties In The Model From Strongly Typed Custom HtmlHelper

Mar 18, 2011

I have a view that is strongly typed and its model is of type LogOnModel. That LogOnModel has anotated properties like this one:

[Required(ErrorMessage = "Please enter your password")]
[DataType(DataType.Password)]
[Display(Name = "Password", Description = "Your secreet password")]
public string Password { get; set; }

All of them has Display anotation with Display.Descripion property set. I want to create HtmlHelper extension method that will output <span> containg the value of Display.Description property. So for example if I called my extension method DescriptionFor than this code:

<%: Html.DescriptionFor(m => m.Password) %>

should produce following html: <span>Your secreet password</span>

C# - Creating A List Of Dataset Fields And Form Fields For Easy Updating?

Feb 25, 2011

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:

txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();

And conversely when it's time to submit.

formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();

I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.

So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.

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)

Best Practices Concerning View Model And Updates With Subset Of Fields

Jan 17, 2010

By picking MVC for developing our new site, I find myself in the midst of "best practices" being developed around me in apparent real time. Two weeks ago, NerdDinner was my guide but with the development of MVC 2, even it seems outdated. It's an thrilling experience and I feel privileged to be in close contact with intelligent programmers daily. Right now I've stumbled upon an issue I can't seem to get a straight answer on - from all the blogs anyway - and I'd like to get some insight from the community. It's about Editing (read: Edit action). The bulk of material out there, tutorials and blogs, deal with creating and view the model.

So while this question may not spell out a question, I hope to get some discussion going, contributing to my decision about the path of development I'm to take. My model represents a user with several fields like name, address and email. All the names, in fact, on field each for first name, last name and middle name. The Details view displays all these fields but you can change only one set of fields at a time, for instance, your names. The user expands a form while the other fields are still visible above and below. So the form that is posted back contains a subset of the fields representing the model. While this is appealing to us and our layout concerns, for various reasons, it is to be shunned by serious MVC-developers.

I've been reading about some patterns and best practices and it seems that this is not in key with the paradigm of viewmodel == view. Or have I got it wrong? Anyway, NerdDinner dictates using FormCollection och UpdateModel. All the null fields are happily ignored. Since then, the MVC-community has abandoned this approach to such a degree that a bug in MVC 2 was not discovered. UpdateModel does not work without a complete model in your formcollection. The view model pattern receiving most praise seems to be Dedicated view model that contains a custom view model entity and is the only one that my design issue could be made compatible with.

It entails a tedious amount of mapping, albeit lightened by the use of AutoMapper and the ideas of Jimmy Bogard, that may or may not be worthwhile. He also proposes a 1:1 relationship between view and view model. In keeping with these design paradigms, I am to create a view and associated view for each of my expanding sets of fields. The view models would each be nearly identical, differing only in the fields which are read-only, the views also containing much repeated markup. This seems absurd to me. In future I may want to be able to display two, more or all sets of fields open simultaneously.

MVC :: JQuery Disabled TextBoxFor Causes Model Fields To Be Null?

Jul 19, 2010

So i'm working on the form that i started MVC with - the problem is that i'm NOT using a ViewModel for the view, its an actual Linq to SQL object. And so far it works fine. This form is a beast and id rather not refactor it to use viewmodels....

My big problem now is that depending some condition, i pretty much set almost everything to disabled when a particular dropdown is selcted (to mimic a deactivated state) - when the user hits submit, the model fields are now null, even tho you can see them filled in (just greyed out and unselectable) and validation refuses them.

Is there anyway around this other than to refactor the Views to use ViewModels (and set different validation rules so submit works)?

MVC :: Query String Parameters And View Model Fields?

Feb 15, 2010

i just noticed that if my controller has a parameter with a name that matches the name of a field in my view model, and the view emits the value of the model's field, the value emitted is that passed in the query string, not the one set by the controller. is this by design?

here is what i mean:

my view model:

public class MyViewModel
{
int id;
string name; [code]....

sending a request to "create?id=1234" emits "1234" in the hidden field instead of "1".

MVC :: Model Validation Happens Automatically With LinqToSql DateTime Fields, But Not Other NOT NULL Fie...

Mar 15, 2010

I'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty.

My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields?

Sure, I have successfully added the MetadataType(typeof<t>) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?
