Reusable Code

[jjmendo]

I'm createing a web form and have a dropdownlist. the dropdownlist lists all the states. I would be placing this dropdownlist in several different pages. I'm unsure as to how to create a class for the dropdownlist code to be reused. I've always placed the code in the codebehind and haven't created any classes. Could someone help as to how I would create the class and call it from the aspx page.
Thanx.

There's two approaches you can take:

1. Write a class in another assembly that you can reuse, that accepts a ListBox and populates it with your list of states. Call it from your code-behind by using the new operator on it (like any other class).

2. Create a custom ASP.NET control that is a state/province picker. You'll want a book like "ASP.NET Server Controls and Components" from Microsoft Press. This is much more difficult, but you gain a control that you can put in your toolbox and reuse just by dragging it onto your form.
