Exclude content types

Extend ContentListEntity

In order to exclude content types form the content list widget, you need to inherit and extend the ContentListEntity class and add TypeBlacklist paramater to exlclude content types or add Type paramater to specify a list of allowed contet types.

For example:

using Progress.Sitefinity.AspNetCore;
using Progress.Sitefinity.AspNetCore.Widgets.Models.ContentList;
using Progress.Sitefinity.Renderer.Designers.Attributes;
using Progress.Sitefinity.Renderer.Entities.Content;
namespace SandboxWebApp.Entities
{
/// <summary>
/// Extended entity class for the ContentBlock view component.
/// </summary>
public class ExtendedContentListEntity : ContentListEntity
{
/// <inheritdoc />
[ContentSection(Constants.ContentSectionTitles.SelectContentToDisplay, 0)]
[Content(
Type = $"{KnownContentTypes.ListItems}, {KnownContentTypes.News}",
TypeBlacklist = "Telerik.Sitefinity.DynamicTypes.Model.PressReleases.Pressrelease"
)]
public override MixedContentContext SelectedItems
{
get
{
return base.SelectedItems;
}
set
{
base.SelectedItems = value;
}
}
}
}

Then you need to register the entity in the Program.cs file:

builder.Services.AddSingleton<ientityextender, entityextender<contentlistentity,="" sandboxwebapp.entities.extendedcontentlistentity="">>(); </ientityextender,>
