Short Name:
Host Items and Host Controls Overview

Type of Entity:
C#

Abstract:
In Microsoft Visual Studio 2005 Tools for the Microsoft Office System, the Microsoft.Office.Tools.Word.Document and Microsoft.Office.Tools.Excel.Worksheet classes are known as host items. These classes have designers that are the visual representation of the class, very much like a Windows Forms designer. Host items can be bound to data and are a container for controls such as host controls and Windows Forms controls. There is also a Microsoft.Office.Tools.Excel.Workbook host item, but it does not act as a container for host controls. The workbook functions as a component tray, enabling you to drag a component, such as the DataSet onto its design surface.
