IRibbonExtensibility Interface


The interface through which the Ribbon user interface (UI) communicates with a COM add-in to customize the UI.

public interface class IRibbonExtensibility
public interface IRibbonExtensibility
Public Interface IRibbonExtensibility


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; 


The IRibbonExtensibility interface has a single method, GetCustomUI.



Loads the XML markup, either from an XML customization file or from XML markup embedded in the procedure, that customizes the Ribbon user interface.
