With that, you have a fairly complete functioning example of a custom data-bound control, created as a user control, containing other data-bound controls, and managed through a contained binding source Approaching things this way gives you a clean way to encapsulate functionality in a single control that can be reused in many places, and lets you harness the powers of the built-in Framework data-bound controls to their full extent without having to know anything about them beyond their public properties, methods, and events You could certainly continue to enhance the capabilities of this control by surfacing additional properties on your control that you then delegate in appropriate ways to the contained controls and components You might want to expose the contents of the filtered list so that other programmers can grab those filtered data items and do something with them as their own list Obviously, caching all the autocomplete values of every row for the selected filter field in the grid in memory can be a scalability concern if you try to use this control for very large data sets To address that, you would need to come up with a more robust way of populating the autocomplete listor do away with that requirement By doing things like this, you add capabilities to your control with minimal code, but limit what is exposed to the user of your control, which is a good approach to component-oriented development from an encapsulation point of view If you really want to expose the full API or a significant subset of it from the grid to the users of your control, you may want to expose just a property on your control that gives them direct access to a reference to the grid However, that still won't give them access to the designer capabilities of working with a DataGridView control, so if you need to support that as well, you might need to step back to deriving a class from the DataGridView control At that point you have to tackle the full complexities of integrating custom code into the processing model of the Framework control, which again requires pretty intimate knowledge of all of the control's internal details An alternate approach would be to create a custom designer class for your control that provides similar capabilities to that of the DataGridView, as discussed in the sidebar Supporting Rich Design-Time Declarative Programming" " The full FilteredGrid example and a sample hosting Windows Forms application are available in the CustomControls project download code for this book.

(2.7.19)

Although these steps proceed in roughly chronological order, they represent an iterative process. Designers can expect to cycle through Steps 3 through 5 several times until the requirements are stable. This is a necessary part of the process and shouldn t be short-circuited. A detailed description of each of these steps follows.

with (3 = V o~h. Hence, given the T-matrix elements, the scattering matrix elements for F can be computed according to (2.7.17).

In this section, we shall derive the unitarity and symmetry properties of the T-matrix. The unitarity property is a result of energy conservation for a nonabsorptive scatterer, and symmetry is a result of reciprocity.

Selecting a control in the designer and setting properties or using context menus to alter the behavior of that control is a form of declarative programming This is something that Windows Forms programmers have grown to expect from rich controls due to the support for this programming paradigm that Visual Studio provides You have seen a few simple examples of providing rich designer support in the attributes that you added to the DataSource and DataMember properties in the FilteredGrid You will see a few others with the ToolboxItem and ToolboxBitmap attributes in the next example You should also include Description and Category attributes for any properties that will be exposed in the Properties window You have seen that any properties added to your control that have types recognized by Visual Studio will be automatically displayed in the Properties window when your control is selected You will be able to edit those properties with the editors associated with that type in Visual Studio Visual Studio provides a great deal of capability that enables you to go well beyond this You can use a variety of other attributes to influence other design-time behaviors, and you can create custom type converters that allow the Properties window to convert input strings into complex types that the Properties window wouldn't ordinarily recognize You can design custom editors that can plug into the Properties window so you can edit your complex types in a rich graphical way, similar to the Anchor property on form controls or the Color selection dialog that is presented for properties of type Color

The total field is a summation of incident and scattered fields. We use (2.7.2) and (2.7.3) and also the fact that regular wave solution is a combination of outgoing waves (Hankel functions of first kind) and incoming waves (Hankel functions of second kind), that is, in = (h~l) + h~2 )/2. We use superscript (2) to denote that the spherical Hankel function of the seco~d kind is used in the vector wave function. Defining the scattering matrix S as
