Hi Erik sort of just trying to relate it back to my situation.

My Modul builder deck looks like this

//------------------------------------------------------------------------------ // //------------------------------------------------------------------------------

using System; using System.Collections.Generic; using System.Linq.Expressions; using System.Web; using Umbraco.Core.Models; using Umbraco.Core.Models.PublishedContent; using Umbraco.Web; using Umbraco.ModelsBuilder; using Umbraco.ModelsBuilder.Umbraco;

namespace IBDStarterKit.Models { ///

Window Tiles

[PublishedModel("IBDWindowTilesComponent")] public partial class IbdWindowTilesComponent : PublishedContentModel { // helpers

pragma warning disable 0109 // new is redundant

    [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Umbraco.ModelsBuilder", "8.1.6")]
    public new const string ModelTypeAlias = "IBD_Window_Tiles_Component";
    [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Umbraco.ModelsBuilder", "8.1.6")]
    public new const PublishedItemType ModelItemType = PublishedItemType.Content;
    [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Umbraco.ModelsBuilder", "8.1.6")]
    public new static IPublishedContentType GetModelContentType()
        => PublishedModelUtility.GetModelContentType(ModelItemType, ModelTypeAlias);
    [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Umbraco.ModelsBuilder", "8.1.6")]
    public static IPublishedPropertyType GetModelPropertyType<TValue>(Expression<Func<Ibd_Window_Tiles_Component, TValue>> selector)
        => PublishedModelUtility.GetModelPropertyType(GetModelContentType(), selector);

pragma warning restore 0109

    // ctor
    public Ibd_Window_Tiles_Component(IPublishedContent content)
        : base(content)
    { }

    // properties

    ///<summary>
    /// Heading
    ///</summary>
    [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Umbraco.ModelsBuilder", "8.1.6")]
    [ImplementPropertyType("windowHeading")]
    public string WindowHeading => this.Value<string>("windowHeading");

    ///<summary>
    /// Tiles
    ///</summary>
    [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Umbraco.ModelsBuilder", "8.1.6")]
    [ImplementPropertyType("windowTiles")]
    public IEnumerable<Ibd_Window_Tile> WindowTiles => this.Value<IEnumerable<Ibd_Window_Tile>>("windowTiles");
}

So I have added this declaration

public partial class Ibd_Window_Component {
    [ImplementPropertyType("windowTiles")]
    public IEnumerable<Ibd_Window_Tile> WindowTiles => RelatedContentComposition.GetRelatedPages(this);
}

But its not quit there RelatedContentComposition is underlined in red.

Hi Daniel,

You need to add your custom implementation in that place, you just copied my custom implementation ;)

You can do something like this:

 [ImplementPropertyType("windowTiles")]
    public IEnumerable<Ibd_Window_Tile> WindowTiles
    {
        get
        {
            // Do custom stuff here

            // This is what the basic modelsbuilder returns
            return this.Value<IEnumerable<Ibd_Window_Tile>>("windowTiles");
        }
    }

I suggest you create a new file with the partial class in so it doesn't get overwriten when you rebuild your modelsbuilder models.

Then you can rebuild your UmbracoModels (the basic implementation in the generated models file will then disapear)

Thanks Eric I understand that and I have my partial declaration in an other file etc.

And I have done this before to add new variables to the class. But they are new variables. not modifying the old ones so the extent of my knowledge there is to do something like

public partial class Ibd_Window_Component { // Where this is my doc type 
    public string AdditonalString {get;set;}
}

But this is not what Im trying to do.

I want to use it like this in a controller for setting my the content of the model to pass to a partial view

So this is the code I use at present that is a direct duplication of the doctypes. Which I are trying to get away from.

        Ibd_Window_Tiles Model = new Ibd_Window_Tiles();

        Model.WindowHeading = "Hello";
        Model.WindowTiles = new List<Ibd_Window_Tile>();
        ...........
        Ibd_Window_Tile Tile= new Ibd_Window_Tile();
        Model.WindowTiles.Appent(Tile);

etc.

the problem is that if I use the doctype version IbdWindowTiles_Componet etc then the error is that WindowHeading is read only.

Is my question is still, I know I need to put something in the // Do something here.

But I don't understand and cant find any examples of what to put here.

There must be a way of doing this without duplicating code.

Hi Daniel,

Perhaps I misunderstand you, but is it correct that you don't get the tile content from Umbraco (since you are populating it in code)?

If this is the case, why not create a custom viewmodel and pass this model to the partial view?

With the override example you can return whatever you want, for example:

[ImplementPropertyType("windowTiles")]
public IEnumerable<YourCustomModel> WindowTiles
{
    get
    {
        // Do custom stuff here
        return new List<YourCustomModel> {
            new YourCustomModel {
                Title =  "This is the title"
            }
        };
    }
}
