Namespaces Overview

In Spread for ASP.NET, namespaces are organized to contain objects according to how they are used in the Spread component. The Spread component comprises six namespaces. The objects in the component fall into these categories:

objects that represent parts of the spreadsheet, like column, rows, and cells
objects that represent parts of the component for editing cells in the spreadsheet
objects that represent parts of the component for the underlying template or model of the spreadsheet
objects that represent parts of the component for rendering or displaying the spreadsheet
objects that represent the chart control
objects that represent data binding

For each of these there is a specific namespace. The namespaces are organized as follows:

Namespace	Description
FarPoint.Web.Spread	Provides the base classes, interfaces, enumerations, and delegates for Spread.
FarPoint.Web.Spread.Chart	Provides the base classes, interfaces, and enumerations for the Spread Chart component.
FarPoint.Web.Spread.Data	Provides the base classes and interfaces for data binding for the Spread spreadsheet component.
FarPoint.Web.Spread.Editor	Provides the base classes and interface for the controls used to edit cells.
FarPoint.Web.Spread.Model	Provides the base classes, interfaces, and enumerations for the Spread models.
FarPoint.Web.Spread.Renderer	Provides the base classes and interfaces for the controls used to render cells.

The spreadsheet objects and event arguments are in classes in the main Spread namespace. For a discussion of how to work with these objects, refer to Shortcut Objects.

The conceptual objects, the more abstract objects, are referred to as "models." These models are responsible for managing the style information, formatting, and data in the Spread component. These are found in the Model namespace. In Spread, you can use the default models or extend them through inheritance. Refer to Underlying Models for more information on models.

The spreadsheet and cell type objects call the model objects. If you are new to working with Spread, or are new to developing in an object-oriented environment, you might want to use the spreadsheet and cell type objects at first, as you become familiar with features of Spread. However, intensive use of these objects can degrade your application’s performance.

If you are an experienced programmer, you might want to use the model objects directly, instead of accessing them through the shortcut objects. If you want to extend Spread for ASP.NET, you must use the model objects to do so.
