I'm building a new Umbraco 8 site based on a much older WebForms site. Most of the site is being rebuilt in MVC with proper Umbraco integration, but there are a couple of legacy pages which, for the moment, need to stay as WebForms pages - we just do not have the resources to rebuild them. I've been asked to see if we can incorporate the Umbraco-based Header and Footer views into the WebForms aspx pages in some fashion.
I just need to be able to pull a few facets of the HomePage ContentModel in - a list of its Children to construct the same set of top links as is in the MVC pages, and one of the properties of its IPublishedContent so that I can get the URL of a banner image. Is there any way at all that I can access Umbraco.ContentAtRoot() or the general UmbracoViewPage structure from within an aspx context? Can I get the information directly from Umbraco's SQL database tables?
to make use of the homepage.
I was then able to use a slightly modified version of Keith's answer from https://stackoverflow.com/questions/702746, melded with aarondcoleman's answer, to render the partial view as a string that I could then include in the WebForms page.
public static string RenderPartial(string partialName, object model)
{
//get a wrapper for the legacy WebForm context
var httpCtx = new HttpContextWrapper(HttpContext.Current);
//create a mock route that points to the empty controller
var rt = new RouteData();
rt.Values.Add("controller", "WebFormController");
//create a controller context for the route and http context
var ctx = new ControllerContext(new RequestContext(httpCtx, rt), new WebFormController());
//find the partial view using the viewengine
var view = ViewEngines.Engines.FindPartialView(ctx, partialName).View;
//create a view context and assign the model
var vctx = new ViewContext(ctx, view, new ViewDataDictionary { Model = model }, new TempDataDictionary(), new StringWriter());
// This will render the partial view direct to the output, but be careful as it may end up outside of the <html /> tag
//view.Render(vctx, HttpContext.Current.Response.Output);
// Better to render like this and create a literal control to add to the parent
var html = new StringWriter();
view.Render(vctx, html);
return html.GetStringBuilder().ToString();
}
(HeaderContent being declared as a public string in the partial class of the page)
(Incidental note, when I put
<%= HeaderContent %>
into the code of the aspx page, I initially got an error from Visual Studio that it couldn't find HeaderContent, but the error vanished once I compiled and actually ran the page, so I think that was just Visual Studio being weird.)
Umbraco 8 - getting umbraco-based information into WebForms legacy page
Hi folks
I'm building a new Umbraco 8 site based on a much older WebForms site. Most of the site is being rebuilt in MVC with proper Umbraco integration, but there are a couple of legacy pages which, for the moment, need to stay as WebForms pages - we just do not have the resources to rebuild them.

Is there any way at all that I can access Umbraco.ContentAtRoot() or the general UmbracoViewPage structure from within an aspx context? Can I get the information directly from Umbraco's SQL database tables?
Thanks
I eventually solved this one myself with help from Google.
For anyone else stuck with the same issue, if you include

and then in the code-behind Page_Load function,
