I am writing a UserControl to dynamically create an Edit / Update form based on the properties of a Document Type.

I am using the following code:

var dataEditor = propertyType.DataTypeDefinition.DataType.DataEditor;
var fullTypeName = dataEditor.GetType().ToString();

but fullTypeName equals "umbraco.editorControls.textfield.TextFieldEditor" for both Textstring and TextboxMultiple properties!?

Is there a way to detect which type it is, so that I can create a multi-line text box if necessary?
