Add css, js or other content to a views head from partial views

Question

I have found a few questions relating to this, but generally there are many different answers and they all seem very messy and complex.

If that is what needs to be done,

Answer 1

You can do this with sections. For example: I have more than two view which each other has same _Layout.My Index action in Company Controller has a sections as follow:

@model Invoice.Model.HelperClasses.CompanyViewModel

@{
   ViewBag.Title = "Companies";
   Layout = "~/Views/Shared/_Layout.cshtml";
}
@section usage{

}
@section other{



}
@section script
{
  
}

and Display Action in Invoice controller has same sections but different css and js as follow:

@model Invoice.Model.HelperClasses.InvoiceViewModel

@{
  ViewBag.Title = "Index";
  Layout = "~/Views/Shared/_Layout.cshtml";
}
@section usage{
@**@
}
@section other{
  
  
  
}
@section script
{
  
  
  
}

and then you can use this section in _Layout but its required argument should be false. Look at:

  @RenderSection("usage", required: false)

  @RenderSection("other", required: false)

  @RenderSection("script", required: false)
