Challenges with implementing @Html.EditorForModel

Currently, I am developing a web application using asp.net's mvc-5 framework. In this project, I have implemented the following model class:

public class Details4
    {
        [HiddenInput(DisplayValue=false)]
        public string RESOURCENAME { set; get; }
        [Display(Name="Account Name")]
        [Required]
        public string ACCOUNTNAME { set; get; }
        [Display(Name = "Resource type")]
        [Required]
        public string RESOURCETYPE { set; get; }
        [DataType(DataType.Password)]
        [Required]
        public string PASSWORD { set; get; }
        [Display(Name = "Description")]
        [DataType(DataType.MultilineText)]
        public string Description { set; get; }
        [Display(Name= "URL")]
        [Url]
        public string RESOURCEURL { set; get; }
        [Display(Name="Owner Name")]
        [Required]
        public string OWNERNAME { set; get; }
        [Display(Name = "Resource Group Nam")]
        public string RESOURCEGROUPNAME { set; get; }
        [JsonProperty("Domain")]
        public string DomainName { set; get; }
        [JsonProperty("DNSNAME")]
        public string DNSNAME { set; get; }
         [Display(Name = "Department")]
        public string DEPARTMENT { set; get; }
         [Display(Name = "Location")]
        public string LOCATION { set; get; }
        public List<RESOURCECUSTOMFIELD> RESOURCECUSTOMFIELD { set; get; }
    }

 public class RESOURCECUSTOMFIELD
    {
        public string CUSTOMLABEL { set; get; }
        public string CUSTOMVALUE { set; get; }
    }

Instead of my usual approach of using @Html.EditorFor() and LabelFor() at the field level, for this model, I wanted to utilize @Html.EditorForModel to reduce markup on the view:

@Html.EditorForModel()

However, the outcome was not entirely as expected:

I would appreciate any advice on how to address these issues:

Is there a method to display the ResourceType field as a dropdown list? When rendering separate fields, I can use @Html.DropDownlistFor, but I'm uncertain about handling this when using @Html.EditorForModel.

How can I alter the generated layout? Typically, throughout my application, I maintain the label to text box layout as follows:

<div>
    <span class="f">@Html.DisplayNameFor(model => model.Resource.RESOURCENAME)</span> 
   @Html.EditorFor(model => model.Resource.RESOURCENAME) 
    @Html.ValidationMessageFor(model => model.Resource.RESOURCENAME)                                              
</div>

In this layout, the label and text are displayed on the same line, with the label wrapped in a class=f that renders it in bold font. Is it possible to modify the output from EditorForModel to showcase the label and text box on the same line instead of being on two separate lines?

Can I force the EditorForModel to render the columns of the RESOURCECUSTOMFIELD list?

Answer №1

EditorForModel default template doesn't offer much customization. Creating your own EditorTemplate is the solution to all your problems. Refer to this helpful tutorial. You'll need to manually define all properties once for each model and store the template in a folder named EditorTemplates/ for universal application usage. Addressing your concerns:

With your custom template, you have the flexibility to use different input types for properties. By default, the editor generates a textbox (or dropdown for enum).
You can design your own layout within the template, catering to your specific requirements.

Create an editor template for RESOURCECUSTOMFIELD and apply it in your main template. You can even create a template for

IEnumerable<RESOURCECUSTOMFIELD>

:

@model IEnumerable<RESOURCECUSTOMFIELD>
@foreach(var customModel in Model)
{
    @Html.LabelFor(m => customModel.CUSTOMLABEL )
    @Html.TextBoxFor(m => customModel.CUSTOMVALUE )
}

Incorporate it like this (in your main template):

   @Html.EditorFor(m => m.RESOURCECUSTOMFIELD )

If necessary, you can utilize a DisplayTemplate to modify the behavior of DisplayFor when working with the model.

1. If you want to customize the display of a model field, you can use [UIHint("custom_template")]. Here's an example:

public class Class1
    {
        public int id { get; set; }
        public string Name { get; set; }
        public string LastName { get; set; }

        [UIHint("gender_template")]
        public string Gender { get; set; }
    }

You'll need to create a gender_template.cshtml file in Shared/EditorTemplates as shown in the picture below.

An example code snippet for gender_template.cshtml:

@Html.DropDownList(
    "",
    new SelectList(
        new[] 
        { 
            new { Value = "Male", Text = "Male" },
            new { Value = "Female", Text = "Female" },
        },
        "Value",
        "Text",
        Model
    )
)

In your View page, add the following code:

@model MvcApplication2.Models.Class1 
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>
@Html.EditorForModel()

After running the view page, you'll see the customized result like this:

You can create more custom templates according to your needs.

To use @Html.DisplayFor syntax, similar to @html.EditorFor, you should create template files in Shared/DisplayTemplates and write your own HTML syntax in those template files.
