Field Views

Configuring field views in Konstrukt, the back office UI builder for Umbraco.

Field Views allow you to customize the markup used by a field when displayed in a list view. Field Views are implemented as .NET Core View Components that are passed a single KonstruktFieldViewsContext argument with information about the entity / field being rendered.

Defining a field view

You can define a field view in one of two ways.

1. A simple view file for the built in KonstruktFieldView view component

The simplest way to define a field view for non-complex fields is to place a view file in the /Views/Shared/Components/KonstruktFieldView folder with the following markup.

@model Konstrukt.Web.Models.KonstruktFieldViewContext
<!-- Insert your markup here -->

When registering a simple view file view you pass the name of the view file (excluding the .cshtml file extension) to the relevant API method.

2. A completely custom view component

To define a more complex field view you can create your own view component class (which can use dependency injection for any required dependencies) with the following signature

// Example
public class MyComplexFieldViewViewComponent : ViewComponent
    public async Task<IViewComponentResult> InvokeAsync(KonstruktFieldViewContext context)
        // Do your custom logic here

        return View("Default", model);

It's important to node that the KonstruktFieldViewContext parameter to the InvokeAsync method MUST be named context.

For the view element of your component, based on the example above, you would place a file Default.cshtml into the /Views/Shared/Components/MyComplexFieldView folder with the following markup

@model Namespace.Of.Model.Returned.By.Custom.ViewComponent
<!-- Insert your markup here -->

The field view context

Field view components are passed a KonstruktFieldViewContext object with the following information.

public class KonstruktFieldViewContext
    public string ViewName { get; set; }
    public object Entity { get; set; }
    public string PropertyName { get; set; }
    public object PropertyValue { get; set; }

Setting the field view of a list view field

A field view is assigned to a list view field as part of the list view configuration. See List View Documentation for more info.
