The IRibbonExtensibility interface has a single method, GetCustomUI.


In the following example, written in C#, the IRibbonExtensibility interface is specified in the class definition. The procedure then implements the interfaces's only method, GetCustomUI. This method creates an instance of a SteamReader object that reads in the customized markup stored in an external XML file.

public class Connect : Object, Extensibility.IDTExtensibility2, IRibbonExtensibility 
public string GetCustomUI(string RibbonID) 
   StreamReader customUIReader = new System.IO.StreamReader("C:\\RibbonXSampleCS\\customUI.xml"); 
   string customUIData = customUIReader.ReadToEnd(); 
   return customUIData;
