I'm failing at getting the selected item on a mvc dropdown list. I can't stand viewdata, and every example uses it. Here is my code,
//controller
public ActionResult Register(Models.Person APerson)

public class Person

public Person().............
i've got a problem with asp.net routing. My route looks like this:

but if there is a directory with the same name (in my case: "Articles") in my root directory, asp.net routing doesn't work and causes the error: "The resource cannot be found."
I'm working on a custom menu system in asp.net that populates a horizontal menu on the fly based on which menu item is selected from the website's main menu.This 2nd menu is populated from a custom XML file in the website's root directory.(See http://loganyoung.wordpress.com/2010/06/03/asp-net-horizontal-submenu-from-xml/ for details).At the time I'd written that post, it did work, but my development environment has changed and now I'm getting an error saying that the XML file can't be found.
View 2 RepliesOK, I was having some deployment issues on IIS 5.1, but at one point (right before the machine died) I was able to serve the files. I'm not certain what is lacking in my current case, but now I'm trying to deploy on IIS 6, and cannot get anything but "404 not found" errors. It's driving me nuts.
Just to be sure the site is working, because it isn't in the web root (virtual directory), I dumped a Web Forms website in there, and it worked just fine. I've tried setting up a wildcard in IIS by going to the properties of the site, and in the area under the file extension mappings, I clicked Insert to create a wildcard, assigning it to the aspnet_isapi.dll file. No dice. And yes, I remembered to uncheck the "Verify file exists" checkbox. Since this is IIS 6, I also made sure I had the Default.aspx page, with the code:
[Code]....
So all should be good. But it's not. I've combed over at least 6 websites and related links on getting MVC 2 to work on IIS 6, but nothing has worked so far. I cannot purchase the url rewritier mentioned in Steve Sanderson's blog, nor can I use the free version, since my application isn't the only web site running on this server. I can't use extensions for the pages, either. This is a crude hack I really don't want to deploy in a production application.
I'm using asp.net mvc 2 applications and while clicking on the link,it shows the error as "HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly."The site was deployed in my localhost (IIS 6) web server.For example the link
http://localhost/news/details/My_First_News_title shows the above error but the link
http://localhost/news/index works fine in the browser.And also we added wildcard in IIS configuration and unchecked the "verify file exists options in IIS.
I followed MVC 2 source to create a CheckBoxList helper.
I was able to identify the problem I am having but not able to solve it.
On my view I have the following:
[Code]....
The problem is in the bold part ...
The newSelectList is equal to selectList but all items were deselected.
What am I missing?
how can i disable first value in the select list when the checkbox is clicked
View 2 RepliesI'm working on a MVC3 web application. I want a list of categories shown when editing a blo from whe applications managements system. In my viewmodel i've got the following property defined for a list of selectlistitems for categories.
/// <summary>
/// The List of categories
/// </summary>
[Display(Name = "Categorie")]
public IEnumerable<SelectListItem> Categories { get; set; }
The next step, my controller contains the following edit action where the list of selectlistitems is filled from the database.
public ActionResult Edit(Guid id)
{
var blogToEdit = _blogService.First(x => x.Id.Equals(id));
var listOfCategories = _categorieService.GetAll();
var selectList = listOfCategories.Select(x =>new SelectListItem{Text = x.Name, Value = x.Id.ToString(), Selected = x.Id.Equals(blogToEdit.Category.Id)}).ToList();
selectList.Insert(0, new SelectListItem{Text = Messages.SelectAnItem, Value = Messages.SelectAnItem});
var viewModel = new BlogModel
{
BlogId = blogToEdit.Id,
Active = blogToEdit.Actief,
Content = blogToEdit.Text,
Title = blogToEdit.Titel,
Categories = selectList //at this point i see the expected item being selected
//Categories = new IEnumerable<SelectListItem>(listOfCategories, "Id", "Naam", blogToEdit.CategorieId)
};
return View(viewModel);
}
When i set a breakpoint just before the view is being returned, i see that the selectlist is filled as i expected. So at this point everything seems to be okay. The viewmodel is filled entirely correct.
Then in my view (i'm using Razor) i've got the following two rules which are supposed to render the selectlist for me.
@Html.LabelFor(m => m.Categories) @Html.DropDownListFor(model=>model.Categories, Model.Categories, Model.CategoryId)
@Html.ValidationMessageFor(m => m.Categories)
When I run the code and open the view to edit my blog, I can see all the correct data. Also the selectlist is rendered correctly, but the item i want to be selected lost it's selection. How can this be? Until the point the viewmodel is being returned with the view everything is okay. But when i view the webpage in the browser, the selectlist is there only with out the correct selection. What am I missing here? Or doing wrong?
Is there a way to remove items from a SelectList?
View 1 RepliesI cannot get my code to work with the usual workarounds. I have a model which exposes a SelectList and a value for the selected item in it. The list is built like: new SelectList(persons, "Id", "Name");
where persons is an array of type Person with a *string* property named Id and a string property named Name. My model has a SelectList property returning a list built as shown, and a SelectedPersonId *string* property which should be updated by the dropdown. Here's my view code:
Html.DropDownListFor(m => m.SelectedPersonId, Model.PersonList)
I can see the persons in the dropdown and select one item, but the model's SelectedPersonId property never gets updated (I get a null). Of the two workarounds I found googling around, one stated to build the SelectList in the model, using the constructor shown above; another recommended to ensure that the selected value is a string. I did both, but still it does not work.
I had been building my SelectLists in the View, but I found examples doing it in code that I liked better. Now I'm creating one of my SelectLists like this:
[Code]....
And all is good, but I'm not sure how to do two things. First, I'd like to add an initial SelectListItem that prompts the user to select a value. When instantiating the SelectList in a loop this is easy, but I was hoping to keep this approach. The second problem is setting the default selected item. In the constructor it shows the 4th parameter to be used for this purpose, but I'm not certain how to do it. There's a property of this object named "DefaultView". It's a boolean, and I'd like that to determine the selected state. Is this possible?

I have written an Enum extension method that allows me to create a view model and allows me to easily bind a generic Enum to a SelctList like:this.ProductStatusList = new ProductStatusTypes().BindToSelectList<ProductStatusTypes>

In my View I can then have:
<% using (Html.BeginForm()) {%>
<fieldset> [code]...
Notice I am using EditorForModel and then a seperate DropDownList. My question is: Is there a way to get the EditorForModel to be clever enough to pick up that I want to use a SelectList instead of a TextBox for status?
I'm trying to display a dropdown on my view page that has a custom text value.
I'm trying to display a list a Contacts. A Contact contains a ContactID, FirstName, and LastName.
<%= Html.DropDownListFor(m => m.ContactId, new SelectList(Model.Contacts, "ContactID", "LastName"), "- Select a Contact -") %>
Right now I'm just displaying the last name, but I'd like to display the first name and last name in the dropdown.
I'm having problems retrieving the values of a selectlist in my form collection. I've tried making a viewmodel with an attribute with the same name as the select list.
I'm honestly just realizing I REALLY don't understand how model binding works with selectlists. I've just been assuming that the following conventions apply:
Name the select list the same thing as the attribute on the model you want it to bind to. Apart from that, I really don't get it. I've looked at several books on it and they're useless frankly. How does a select list work with a) form collection and b) a particular model?
What do I use to set the dataValueField of the Select List when I'm using a list of strings. I want to be able to set the value of the option in the select. If i have:
List<string> list = new List<string>();
list.Add("apple");
list.Add("orange");
and I want my html to be:
<select>
<option value="apple">apple</option>
<option value="orange">orange</option>
</select>
