Hi Mike,

I would also like to extend the fromEditor to dynamicly set the pasted image folder for the grid rte. Did you find a solution for this?

Best regards,,

I looked for information in Google, but my attempts were not crowned with results :(

Very late to the party with this one, but I recently wanted to create a custom view for a Textbox property editor (late-ish into a project so didn't want to go through and change the property editor to a custom one). This was done in v10, but the idea is the same.

First make your new property editor, changing the setup that points to the new view:

using Umbraco.Cms.Core;
using Umbraco.Cms.Core.IO;
using Umbraco.Cms.Core.PropertyEditors;

namespace Something.PropertyEditors
{
    [DataEditor(
        Constants.PropertyEditors.Aliases.TextBox,
        EditorType.PropertyValue | EditorType.MacroParameter,
        "Textbox",
        "/custom_backoffice/views/propertyeditors/customtextbox/customtextbox.html", // This is the path to the view, 
        Group = Constants.PropertyEditors.Groups.Common,
        ValueEditorIsReusable = true)]
    public class CustomTextboxPropertyEditor : TextboxPropertyEditor
    {
        public CustomTextboxPropertyEditor(IDataValueEditorFactory dataValueEditorFactory, IIOHelper ioHelper) : base(dataValueEditorFactory, ioHelper)
        {
        }
    }
}

Then add your custom view to /wwwroot/custom_backoffice/views/propertyeditors/customtextbox/customtextbox.html. This can be whatever you want but as I am overriding the core Textbox I used that as a base (found here)

Lastly remove the core property editor from the collection (otherwise Umbraco will have 2 TextboxPropertyEditors referenced and throw a runtime error when it comes to rendering). You can do this in a composer:

using Umbraco.Cms.Core.Composing;
using Umbraco.Cms.Core.DependencyInjection;
using Umbraco.Cms.Core.PropertyEditors;

public class CoreComposers : IComposer
{
    public void Compose(IUmbracoBuilder builder)
    {
        builder.DataEditors().Exclude<TextboxPropertyEditor>();
    }
}

is working on a reply...
