Hi, I want to display a logo on all the pages.

In my layout I have the following:

<!-- Main Container -->
<div class="container-fluid">
    <header>
        <div class="row">
            <div class="col-xl-3">
                @await Umbraco.RenderMacroAsync("LogoHandler")

            </div>

            <div class="col-xl-9">
            </div>
        </div>
    </header>

And this is the macro partial:

@inherits Umbraco.Cms.Web.Common.Macros.PartialViewMacroPage
@using Umbraco.Cms.Core.Services;
@inject IContentService Services;

@{
if(Model.Content.HasValue("logo")){      
    var mediaItem = Model.Content.Value<IPublishedContent> 
           ("logo");
    var imageHeight = mediaItem.Value<int>("umbracoHeight");
    var imageWidth = mediaItem.Value<int>("umbracoWidth");
    <div style="padding: 20px 0 20px 5px;"><img src="@mediaItem.Url()" alt="@Model.Content.Value("photoAlt")" class="img-fluid" /></div>
  }
}

The problem is that the logo only shows on home page , like, in the root (www.mywebsite.net) and not in any other page in the website

Because all on the other pages if(Model.Content.HasValue("logo")){ returns false.

My question is: can I refer to a parent model? The page in the content tree for the layout is the parent page for the whole website. I guess for any other page it looks for the logo in the current model and not find it.

So how do I make it in the code that in any other page than the home page it will look for the logo in the parent model?

Thanks
