Chapter 38. The System.Web.UI.Design.WebControls Namespace

The types in the
System.Web.UI.Design.WebControls
namespace extend Visual Studio's design-time support
for creating web controls. Most types in this namespace are
designers that provide special design-time-specific HTML (which may
be only slightly different than runtime HTML) and custom
System.Drawing.Design.UITypeEditor classes that
provide the graphic interface for modifying some special properties.
The most detailed implementations of these features can be found in
the types used for the
System.Web.UI.WebControls.DataGrid and
System.Web.UI.WebControls.DataList controls, such
as DataGridComponentEditor and
DataGridDesigner. These classes provide
sophisticated property builders that offer complete design-time
customization in a multipage
"applet."

These designers, UI type editors, and component editors have no
effect on the runtime capabilities of a control. They are also not
used directly in code. That means that the
System.Web.UI.Design.WebControls namespace is
probably of most interest to developers who are interested in
creating controls and add-ins of their own and want to review
Microsoft's examples. Unfortunately, while you can
review the interfaces these types have and extend them in your own
code, the implementation details are not provided. Usually, it makes
most sense to create control designers that inherit from the base
System.Web.UI.Design.ControlDesigner class.

Figures Figure 38-1 and Figure 38-2
show the types in this namespace.
