    Hello,

    I am trying to replicate and extend the native breadcrumbs control. I have made a copy of the files but in the code behind, I am not able to compile the code because it uses Globals.DependencyProvider that is marked as internal to the platform. This is used to get the INavigationManager.

    In this PR ( https://github.com/dnnsof...orm/pull/2795 ) is the correct way of using DI, using the correct base classes, but for what I can see, this was not implemented in the SkinObjectBase. 

    So I think I have 2 options:
    - Request that SkinObjectBase also has access to the DI;
    - Use another class as base for this control. Ex: SkinBase already has a navigation manager accessible.

    Does anyone have some kind of advice on how to go from here?

    Thanks!

      Maybe not a direct anwer to your question but you can also create breadcrumbs using DDR menu.
      As that's fully templatable, there might not be a need to fork the breadcrumbs at all.

        Thanks Timo!
        I will give it a go and try to get away with DDR and xslt.
        Actually I also wanted to add some special context and rules on some nodes based on conditions stored in portal settings, but that might be done using custom tokens ou something similar I suppose.

        Anyway, I will keep looking for a workaround for this Dependency injection on SkinBase derived components.

          You can switch DDR to use a Razor template and do all of the programming that you need to do.

          I think that there are lots of us who have a lot to learn about using the new DI stuff ...

            Tanks Timo and Joe!

            Wow, the power of DDR is almost infinite.
            I managed to use it with one of the Timo's templates for breadcrumbs and added some TemplateArguments so I can implement my logic.
            The goal was to add special links connecting parent / child portals based on portal settings and that was accomplished.

            Thanks guys!

            In case someone else is looking for a similar solution, this is what I've done:
            Created an ASCX for my breadcrumb control.

            

            <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="AlgoBreadCrumbs.ascx.cs" Inherits=".....AlgoBreadCrumbs" %>
            

            <%@ Register TagPrefix="ddr" TagName="MENU" Src="~/DesktopModules/DDRMenu/Menu.ascx" %>
            

            <%@ Register TagPrefix="ddr" Namespace="DotNetNuke.Web.DDRMenu.TemplateEngine" Assembly="DotNetNuke.Web.DDRMenu" %>
            

            <ddr:menu id="mnuBreadCrumb" menustyle="Menus/Breadcrumbs" runat="server">


            In the code behind, I just add the template args when child controls are created:
            


            public partial class AlgoBreadCrumbs : SkinObjectBase
            
    {
            
        public string ParentPortalLink { get; set; } = "https://someportal";
            
        public string ParentPortalName { get; set; } = "Parent Portal";
            


                    /*DDR menu structure and parames takenfrom this thread:
            
        https://dnncommunity.org/forums/aft/1286#4501
            
        */
            
        public AlgoBreadCrumbs()
            
        {
            
        }
            


                    protected override void CreateChildControls()
            
        {
            
            base.CreateChildControls();
            
            SetMenuTemplateArgs();
            
        }
            


                    private void SetMenuTemplateArgs() {
            
            if (mnuBreadCrumb.TemplateArguments == null)
            
                mnuBreadCrumb.TemplateArguments = new System.Collections.Generic.List();
            


                        mnuBreadCrumb.TemplateArguments.Add(new DotNetNuke.Web.DDRMenu.TemplateEngine.TemplateArgument { Name = "ParentPortalLink", Value = ParentPortalLink });
            
            mnuBreadCrumb.TemplateArguments.Add(new DotNetNuke.Web.DDRMenu.TemplateEngine.TemplateArgument { Name = "ParentPortalName", Value = ParentPortalName });
            
        }
            
    }
            


             


            Finally I add the params to the xsl template:
            


            xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
            


            xsl:output method="html"
            


            xsl:param name="ParentPortalLink"
            


            xsl:param name="ParentPortalName"


            Once again, thanks guys!

              Yes, DDR is pretty powerful. So that's why, for most applications I use the UlTokens template!
