User Interface: Default.aspx

---

ASP.NET uses a WYSIWYG approach to build user interfaces. Developers “draw” the interfaces and the ASP.NET will convert them to CSS and HTML.

To create a page, the following ASP.NET options are used: “Project ⇒ Add New Item...” Pick the template “Web Form” and the option “Place code in separate file” if you do not want to put the C# code in the file such as Default.aspx, whose name is entered by you. The code will be saved in another file such as Default.aspx.cs.

This example includes two pages, Default.aspx (home page) and NextPage.aspx. Other than the four Labels or strings, the interface Default.aspx includes the following tools:

• Two TextBoxes with IDs “authorName” and “email,”
• Three Buttons with IDs “insert,” “delete,” and “search,” and
• One Repeater with the ID “searchResult” to display the search results in a table. On the ASP.NET IDE, switch to source view to edit the control’s templates.
