I have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)

I'm about to begin an ASP.NET MVC project and I'm not sure how to approach an aspect of the design. Basically, there is a user site and an admin site. In the admin sites, administartors design a form and send an e-mail link out to a handful of people. When the users click on the link, they are sent to the form.
Essentially what I'm wondering is what are the best practices when the model resembles looks more like a dictionary than a table?
In other words, instead of:
CREATE TABLE FormResponse (ResponseId, FormId, UserId, FirstName, LastName, BirthDay, Comments)
...containing 1 row per complete response
It's more like:
CREATE TABLE FormResponse (ResponseId, FormId, UserId, QuestionId, Value)
...containing 4 rows. 1 for the FirstName, 1 for the LastName, 1 for the BirthDay, and 1 for Comments.

Why is a null parameter being passed to the following controller action?
public FileContentResult GetImageForArticle(ArticleSummary article)

if (article == null || !article.ContainsValidThumbNail()) return null;
return File(article.ThumbNail, article.ThumbNaiType);
}
from the following partial view:

Given the following view model and action using the DefaultModelBinder, it seems to ignore the dictionary, but bind all other properties correctly. Am I missing something here? Looking at the MVC source code this seems legit.
public class SomeViewModel

public SomeViewModel()

I have a form which uploads a photo to my database, and I use a view model to aid in this process.
View Model:
public class GalleryViewModel
{
//Members:
public Gallery _photo { get; set; }
public string _title { get; set; }[code]...
When I debug the code, I see that the in the post method in my controller, all the information from the form is updated in the view model except for the uploadFile which is null.In the form I use enctype = "multipart/form-data". When I use my master page the uploadFile is null but when I use the default MVC master page everything works fine.
Here is my master page:
<%@ Master Language="C#" MasterPageFile="~/views/Shared/GeneralMaster.master" Inherits="System.Web.Mvc.ViewMasterPage" %> [code]....

This might sound like a stupid question, is there a way to add an item to the very top of generic dictionary instead of adding it to end?
Here is my code snippet:

The following code has only thrown a NullReferenceException a handful of times over the last several months, but I'm not exactly sure why. The code isn't mine, but it looks pretty straight forward to me.
[Code]....
The only thing I can think of is that pageType is null when it's being used as a dictionary key, but apparently that is not possible.
The code that calls it is simple:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
_mypage = GetPage();
}
I also thought that the error might be with the _section.Pages, but section is never null and never sets anything. If .Pages[page] returns null, the MyPage constructor simply returns. So what am I missing?

I am using C#. I have got below format values in my SESSION variable ["FROMDATA"], I am using DICTIONARY to store the FORM Posted Data. see the related question.
Below are the some values in my SESSION Variable.
1) key - "skywardsNumber" value-"99999039t"
2) key - "password" value-"a2222222"
3) key - "ctl00$MainContent$ctl22$FlightSchedules1$ddlDepartureAirport-suggest" value-"London"
4) key - "ctl00$MainContent$ctl22$ctl07$txtPromoCode" value-"AEEGIT9"
.
.
....so on
Now I want to create a CLASS with METHOD in it, in which I will just pass the "KEY" and it will first check it for NULL OR EMPTY and then it will return its value from the SESSION Variable ["FROMDATA"].

if I use a Html.Hidden field in my view, when the value click to submit the form I would like to pass this data to the controller. This variable would contain int as key and string as value,
Dictionary<int, string> interestTable = new Dictionary<int, string>();
How can I specify the htmlAttribute fo this variable in my Html.Hidden code?
<% using(Html.BeginForm("Search", "SearchMembers")) { %>
<input type="hidden" name="ResearchInterests" id="researchInterests" value=""/>
<%= Html.Hidden("fullInterestsPath") %>,

I am having problem with rowdatabound, want to add if conditions intact, i am using teh following two if conditions and they don't look right. i found them on google.
If e.Row.RowState = DataControlRowState.Normal Or e.Row.RowState = DataControlRowState.Alternate Then end if
If e.Row.RowState = DataControlRowState.Edit Or e.Row.RowState = 5 Then end if
With datagrids i use these and they work excellent:
If e.Item.ItemType = System.Web.UI.WebControls.ListItemType.Item OrElse e.Item.ItemType = System.Web.UI.WebControls.ListItemType.AlternatingItem Then
end if.....

Say I have a Form model which contains a list of Field objects loaded from a database. Each field object has a type that defines whether it is a listbox, combobox, input or textarea.
What would be the best way for displaying the Field objects correctly? I was thinking in my View using a switch statement and calling a specific partial depending on the case.
[Code]....
Is this a valid approach? What other methods would people recommend to do this?

I have some questions in my mind after went through the video tutorials.
Is Model a entity class type? encapulated attribute and methods (business logic). because i see in videos , people use LINQ to generate models which can only use LINQ to modify/insert/delete data.
Is it a good practice to generate Model using LINQ?

I have a ASP.NET (C#) web page in which I want to enumerate a dictionary in a code render block:

But I get an error like:
Compiler Error Message: CS0246: The type or namespace name 'Dictionary' could not be found (are you missing a using directive or an assembly reference?)
How do I import System.Collections.Generic into the page itself? Here is my page directive:

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?
