How to display Orchard shape only once? - html

Question

I have a common shape that renders some HTML code to display an error dialog.
The HTML code needs to be included only once throughout the whole web site. For scripts and styles Orchard provides the Script.Include() and Style.Include() methods.
I wonder whether there is something similar for HTML code, any ideas?

So many options to do this
Can you add your code to Layout.cshtml in the theme
Create a new widget and attach the shape field then create it on the default layer (so on all pages) with the name of your shape in the shape field
Add the shape in a filter, or anywhere else you have access to the WorkContext :)
Code written from memory, may not compile
using System.Linq;
using System.Web.Mvc;
using Orchard;
using Orchard.DisplayManagement;
using Orchard.Mvc.Filters;
using Orchard.UI.Admin;
public class MyFilter : FilterProvider, IResultProvider {
private readonly dynamic _shapeFactory;
private readonly WorkContext _workContext;
public MyFilter(WorkContext workContext, IShapeFactory shapeFactory)
{
_workContext = workContext;
_shapeFactory = shapeFactory;
}
public void OnResultExecuting(ResultExecutingContext filterContext)
{
// should only run on a full view rendering result
if (!(filterContext.Result is ViewResult)) return;
// front end only
if (AdminFilter.IsApplied(new RequestContext(_workContext.HttpContext, new RouteData()))) return;
var body = _workContext.Layout.Body;
body.Add(_shapeFactory.MyShape());
}
public void OnResultExecuted(ResultExecutedContext filterContext) {}
}
