Renderer Scope property

[bogc]

In Ext.Net 2.5 there used to be a Scope property which allowed one to specify a scope for the renderer JavaScript function.

This is from the Ext.Net\Utility\Renderer.cs 2.5.2 source code:

        /// <summary>
        /// The JavaScript logic to be called when this Renderer fires. The Handler will be automatically wrapped in a proper function{} template and passed the correct arguments for this event.
        /// </summary>
        [ConfigOption(JsonMode.Raw)]
        [DefaultValue("")]
        [NotifyParentProperty(true)]
        [Description("The JavaScript logic to be called when this Renderer fires. The Handler will be automatically wrapped in a proper function{} template and passed the correct arguments for this event.")]
        public virtual string Scope
        {
            get
            {
                return this.State.Get<string>("Scope", "");
            }
            set
            {
                this.State.Set("Scope", value);
            }
        }

In Ext.Net 4 there is no Scope property. What can I use instead to set the JavaScript scope. I have a case where I have a column renderer which needs access to some extra information.

Also, as a side note, the Margins property has been renamed to MarginSpec, however, I haven't found this in the breaking changes list for 3 or 4.

Thank you
