Predefined Field Views

Dignite Cms Mvc has built-in view files for dynamic fields, named after the dynamic field type, placed in the /Views/Shared/ directory of the Dignite.Cms.Public.Web project:

Field

cms-field is used to display field values, passing the EntryFieldViewModel type view model to the view.

Taking the Service Project entry /Views/Entry/Service/Entry.cshtml as an example:

<cms-entry-field field-name="Services" entry="Model"></cms-entry-field>

Services is a matrix type field, which first calls the Dignite.Cms.Public.Web project /Views/Shared/Matrix.cshtml view file, and then internally calls the view of Fields/Matrix/{matrix-block-name}.

In the Service Project entry example, call the Fields/Matrix/service-item view, the complete view path is: /Views/Shared/Fields/Matrix/service-item.cshtml:

@using Dignite.Cms.Public.Web.Models;
@model MatrixBlockViewModel
@{
    var nameField = Model.Type.Fields.First(fd => fd.Name == "name");
    var descriptionField = Model.Type.Fields.First(fd => fd.Name == "description");
}
<h2 class="fs-2 mb-3 fw-bold lh-base">
    <cms-field field="nameField" entry="Model.Block"></cms-field>
</h2>
<div class="rich-text mb-5">
    <cms-field field="descriptionField" entry="Model.Block"></cms-field>
</div>

Parameters of cms-field

• field: An instance of type FormField
• entry: An instance of type IHasCustomFields
• partial-name: The partial view page used to display the field value
