The Dnn Object in Different APIs

The Dnn object is a special object which is available in Dnn, but not in Oqtane.

Razor files inheriting from older base classes have a Dnn object, such as this example:

@inherits Custom.Dnn.Razor12
@{
  // Dnn.Tabs is a TabInfo
  // https://docs.dnncommunity.org/api/DotNetNuke.Entities.Tabs.TabInfo.html
  var pageTitle = Dnn.Tab.Title;
}

All the new base classes, such as Custom.Hybrid.RazorTyped don't have a Dnn object, as they are hybrid and work on Oqtane and Dnn.

Alternative using MyContext / CmsContext

Tip

If you think you need the Dnn property (eg. for accessing the Page Title), best first check if the MyContext / CmsContext can't be used instead.

It has most of the typical properties which you would look for in Dnn.

Example in v16+

@inherits Custom.Hybrid.RazorTyped
@{
  var pageTitle = MyPage.Title;
}

Example in v12+

@inherits Custom.Hybrid.Razor12
@{
  var pageTitle = CmsContext.Page.Title;
}

Get the Dnn Object in Modern Base Classes

You can also still get the Dnn object using this:

var dnn = GetService<ToSic.Sxc.Dnn.Run.IDnnContext>();

This is the same object as the Dnn object in the older base classes.

Warning

Using the Dnn object / service will make your code Dnn-specific and not work in Oqtane.
