What is the best way to retrieve the display name attribute for an item in your model? I see a lot of people using the LabelFor helper for everything, but a label isn't appropriate if I just want to list the data out. Is there an easy way just get the Name Attribute if I just want to print it out in, say a paragraph?
View 1 Repliesi would localize the text of DisplayName attribute: i know that at the moment is not possible (i hope that the next version of mvc will do it automatically) so i tried to search how to do it and i found this link:
LINK TO BLOG'S POST
but i didn't understand how to finish the lookup function.
So, I've got an contact form in my MVC 2 application.
I'd like to programatically email all properties of my "ContactModel".
Here is what I'd like to do in psuedo-ish code:
[Code]....
In case it matters...ContactModel sets up the DisplayName attributes like this:
[DisplayName("First Name")]
public string FirstName {get; set ;}
I'd like to keep this nice and DRY by not repeating the DisplayName names.
Specifically, I'd like to enumerate over each property in my ContactModel, get its DisplayName, and get its submitted value.
As explained in the bug report the MVC's LabelFor generates incorrect FOR attributes for labels.Just wondering what would be the best way to fix this and if anybody knows about the status of the issues?It seems it has not been looked after and marked as Low priority.
View 3 RepliesCan we set an id attribute as I would for something like a table column via: for an html dropdown list element that is created with a helper such as:
<% for (int i = 0; i < Model.Trx.TransactionHolidayCityCollection.Count; i++)
{%>
<%= i > 0 ? "," : "" %>
<%= DropDownData.HolidayDays().ToList().Find(item => item.Value == Model.Trx.TransactionHolidayCityCollection[i].HolidayCityID.Value.ToString()).Text %>
<%} %>
I am using VS2010 & MVC2 to develop a web app. I noticed that HtmlHelper.LabelFor doesnt contain an override that accepts either a css class or html attributes. I was thinking about writing my own override for this, but am struggling with it.
The current LabelFor method accepts a lambda expression and automatically extrapolates the property name, display name (if specified via [DisplayName] attribute and value and generates the label. How do I write my overridden to do the same, but also insert any htmlAttributes specified such as class, style etc.
Does LabelFor look for a template? Is it possible to provide a template for LabelFor?The issue i have is the "for" attribute of label matches a field "id" attribute. In the case of radio or checkbox lists my id's generally take the form of "propertyname_0", "propertyname_1" etc. Simply referencing "propertyname" in the for attribute is not effective.
View 5 RepliesI have a simple application roughly following the nerd dinner tutorial. I am trying to get [DisplayName("Fancy Name")] to pretty up the output from <%= Html.LabelFor(model => model.Booking.Name)%> in my create/edit view. I am using a form view controller which looks like this...
View 3 RepliesI need to build a custom html helper that generates Label and a tooltip Icon(based on the Display(Name = 'MyProperty', Description = 'ToMyToolTip') attribute). This is how my helper looks like so far:
[Code]....
The problem is that the label have a attribute called "for", I need to set this also but do not find the value in the metadata object? Do I have to manually create the value to the "for" attribute? And if so, how is the best way to do that?
Given the following object
public class CompetitionYear : IValidatableObject{public Guid Id { get; set; } [Display(ResourceType = typeof(Terms), Name = "Description")]public string Description { get; set; } [Display(ResourceType = typeof(Terms), Name = "Startdate")]public DateTime Startdate { get; set; } [Display(ResourceType = typeof(Terms), Name = "Enddate")]public DateTime Enddate { get; set; } }
In a View I want to show a table with in the headers the DisplayName of the respective properties.
The view is like this:
@model IEnumerable<CompetitionYear> @{ ViewBag.Title = "Index";} <h2>Index</h2> <p> @Html.ActionLink("Create New", "Create")</p><table> <tr> <th></th> <th> @Html.LabelFor(m => m.FirstOrDefault().Description) </th> <th> @Html.LabelFor(m => m.FirstOrDefault().Startdate) </th> <th> @Html.LabelFor(m => m.FirstOrDefault().Enddate) </th> </tr> @foreach (var item in Model) { <tr> <td> @Html.ActionLink("Edit", "Edit", new { id=item.Id }) | @Html.ActionLink("Details", "Details", new { id=item.Id }) | @Html.ActionLink("Delete", "Delete", new { id=item.Id }) </td> <td> @item.Description </td> <td> @String.Format("{0:D}", item.Startdate) </td> <td> @String.Format("{0:D}", item.Enddate) </td> </tr>} </table>
In the headers I want to show the DisplayName of the property. The only way I can get it working is as shown above. It really looks ugly and I can't imagine there isn't a better solution. Is there a better solution and how does it look like?
I got custom attributes to work on the server and client, now I want to DRY things up just a little more. How do you override the pattern for RegularExpressionAttribute to include the DisplayName?
Right now I am like this:

I would like to use DataAnnotations in my ASP.NET MVC application. I have strongly typed resources class and would like to define in my view models:
[DisplayName(CTRes.UserName)]
string Username;
CTRes is my resource, automatically generated class. Above definition is not allowed. Are there any other solutions?

Why is CultureInfo.DisplayName in [Sami][1] all of a sudden? I use it to display a list of country names. Not a good idea perhaps but it worked until recently and I'm quite sure it was in Swedish (I guess it could have been English.)

View 7 RepliesI have a Car class that I'm trying to display in an MVC 3 view using the WebGrid helper. Below are the Car and it's metadata class.

I am developing asp.net mobile application. I am using LINQ to XML to query XML file. I am using the following query to retrieve the name & value of the query dynamically as follows
var TotalManifolds = from MF in FieldRoot.Element("FIELD-DEFINITION").Element("MANIFOLDS").Elements("MANIFOLD")
join SLT in FieldRoot.Element("FIELD-DEFINITION").Element("SLOTS").Elements("SLOT")
on (string)MF.Attribute("MID") equals (string)SLT.Attribute("PARENT")
select new
{
SlotName = (string)SLT.Attribute("NAME").Value,
SlotValue = (string)SLT.Attribute("NAME").Value
};
In the following statement of above query I want to retrive the name of the attribure dynamically without explicitly specifying the name of the attribute SlotName = (string)SLT.Attribute("NAME").Value Here I am explicitly specifying the name. I want to code which can dynamically retrieve the name of the attribute. I am new to Linq to xml. how this can be done programatically? or can you provide me the link through which I can resolve the above issue ?
