Porting a custom property editor fomr V7 to V8
Trying to port a custom property editor to V8 from V7.

Been looking at https://our.umbraco.com/forum/umbraco-8/96241-rendering-custom-property-editor-in-v8 but I still seem like I'm getting basic errors.

Examples: 'SimplePropertyValueConverter.IsConverter(PublishedPropertyType)': no suitable method found to override

'PublishedPropertyType' does not contain a definition for 'PropertyEditorAlias' and no accessible extension method 'PropertyEditorAlias' accepting a first argument of type 'PublishedPropertyType'
```
using Umbraco.Core.Models.PublishedContent;
using Umbraco.Core.PropertyEditors;

namespace Simple
{
    public class SimplePropertyValueConverter : PropertyValueConverterBase
    {
        public override bool IsConverter(PublishedPropertyType propertyType)
        {
            return propertyType.PropertyEditorAlias != null && propertyType.PropertyEditorAlias.Equals("Simple.Editor");
        }
    }
}
```
From what I understand from that other forum thread, this should be working without any issues.

Hi Thomas

I have a property editor package which is available for v7 and v8

Here is the Property Value Converter for v7: https://github.com/prjseal/Giphy-Property-Editor/blob/umbraco-v7/GiphyPropertyEditorUmbraco7/PropertyValueConverters/GiphyPropertyValueConverter.cs

using System;
using Umbraco.Core.Models.PublishedContent;
using Umbraco.Core.PropertyEditors;

namespace GiphyPropertyEditorUmbraco7.PropertyValueConverters
{
    public class GiphyPropertyValueConverter : PropertyValueConverterBase
    {
        /// <summary>
        /// Gets a value indicating whether the converter supports a property type.
        /// </summary>
        /// <param name="propertyType">The property type.</param>
        /// <returns>A value indicating whether the converter supports a property type.</returns>
        public bool IsConverter(PublishedPropertyType propertyType)
        {
            return propertyType.PropertyEditorAlias.Equals("GiphyPropertyEditorUmbraco7");
        }

        /// <summary>
        /// Gets the type of values returned by the converter.
        /// </summary>
        /// <param name="propertyType">The property type.</param>
        /// <returns>The CLR type of values returned by the converter.</returns>
        public Type GetPropertyValueType(PublishedPropertyType propertyType)
        {
            return typeof(string);
        }
    }
}

And here is the Property Value Converter for v8: https://github.com/prjseal/Giphy-Property-Editor/blob/master/GiphyPropertyEditor/PropertyValueConverters/GiphyPropertyValueConverter.cs

using System;
using Umbraco.Core.Models.PublishedContent;
using Umbraco.Core.PropertyEditors;

namespace GiphyPropertyEditor.PropertyValueConverters
{

    public class GiphyPropertyValueConverter : PropertyValueConverterBase
    {

        /// <summary>
        /// Gets a value indicating whether the converter supports a property type.
        /// </summary>
        /// <param name="propertyType">The property type.</param>
        /// <returns>A value indicating whether the converter supports a property type.</returns>
        public override bool IsConverter(PublishedPropertyType propertyType)
        {
            return propertyType.EditorAlias == "GiphyPropertyEditor";
        }

        /// <summary>
        /// Gets the type of values returned by the converter.
        /// </summary>
        /// <param name="propertyType">The property type.</param>
        /// <returns>The CLR type of values returned by the converter.</returns>
        public override Type GetPropertyValueType(PublishedPropertyType propertyType)
        {
            return typeof(string);
        }

    }

}

The differences I can see are in the v8 version we are using the override keyword in the methods. And I don't know if it makes a difference but instead of .Equals the v8 version of mine is using ==

Hopefully this will help you.

Cheers

Paul

Thank you for your response, however it seems that U8 does not like the override

When I remove and use the code seems to be without errors.
```
return propertyType.EditorAlias == "GiphyPropertyEditor"; 
```
instead of
```
return propertyType.PropertyEditorAlias.Equals("GiphyPropertyEditorUmbraco7");
```
which returns Severity Code Description Project File Line Suppression State Error CS1061 'PublishedPropertyType' does not contain a definition for 'PropertyEditorAlias' and no accessible extension method 'PropertyEditorAlias' accepting a first argument of type 'PublishedPropertyType' could be found (are you missing a using directive or an assembly reference?)

I will check it out further, thank you
