A Web form can be identified by its ... filename extension

.aspx

Displaying a webpage steps

A computer must be running a Web server, which waits for browser connection requests, this occurs in two steps: Browser connects to server requesting a URL Server translates URL into a physical file located within the server's file system and sends the requested file, called a Web page, back to the browser Server breaks connection after sending Web page Web Browser interprets HTML and renders a Web page Postback occurs if client requests Web page again By clicking a button control or pressing the Enter key

A web form Also Uses a file name extension of .aspx Contains text, HTML tags, and HTML controls Also contains Web server controls such as text boxes, list boxes, and buttons Also known as ASP.NET Server controls Similar to Windows Forms controls

...provides several Web controls for displaying and updating a database from a Web application.

ASP.NET

Datasource control - One control is named... , for MS Access databases. The other is named ...., for SQL Server databases.

AccessDataSource SqlDataSource

AutoPostBack defaults to False for the following controls: ...

CheckBox, CheckBoxList, DropDownList, ListBox, ListControl, RadioButton, RadioButtonList, and TextBox.

The ....control looks like a group of check boxes, but works just like a ListBox.

CheckBoxList

When the user hovers the mouse over the image, the mouse cursor changes shape. When the user clicks the image, a ...event is generated.

Click

Contains Web forms and controls, HTML, and program logic in compiled VB code

Web applications use a specialized type of ASP.NET control for accessing databases, generally called a ...control.

DataSource

The ...control makes it easy to view, edit, delete, or add rows to a database table. To use it, you must create a data source, as you did in Tutorial 11-5.

DetailsView

The ...control lets the user select a single item from a list. There are two noticeable differences between the ...and its Windows Forms counterpart, the ComboBox. First, in a ...., the initial value of SelectedIndex is always 0, causing the first item to display when the form is loaded. Second, users cannot enter an arbitrary string into the DropDownList, as they can in a ComboBox.

DropDownList

The ...control offers the ideal way to display a complete table. Similar to the Windows control named DataGridView, it lets you sort on any column, select the column order, and format the data within columns.

GridView

.... can be used to design a Web application's user interface. ....provide a convenient way to align the elements of a Web form.

HTML tables

The ...control provides a simple, easy way to add a link to your page that lets users navigate from the current page to another page. Appears as underlined text

HyperLink

Button type controls

Hyperlink control - no click event/navigates to another url linkbutton control-linkbutton click event generated imagebutton - imagebutton click event generated button click - event generated

Web pages typically use clickable images as navigation tools. You can create the same effect with the ...control.

ImageButton

The ..control looks and behaves much like a HyperLink control, with one major difference: it generates a Click event.

LinkButton

A... runs under a Windows operating system utility named Internet Information Services (IIS).

Local IIS Web site

The ...property lets you limit the number of characters the user is permitted to type.

MaxLength

In Visual Studio, you select ...from the File menu when you want to open an existing Web application.

Open Web Site

The ... control displays a group of radio buttons

RadioButtonList

You can create individual RadioButton controls, but the ...is easier to use. Similar to a ListBox, it has SelectedIndex, SelectedItem, and SelectedValue properties.

RadioButtonList

A ... is also a web site located across a network, with a special requirement: It must be configured with Microsoft FrontPage Extensions.

Remote Site

You can arrange the buttons horizontally or vertically, using the ...property.

RepeatDirection

A ... automatically exists in every Web page. It is an instance of the HttpResponse class.

Response object

In your program code, you can tell the browser to navigate to another page in your application, or any other page on the Web by calling the....method

Response.Redirect

Each Web page in your application is designed using a Web form in Visual Studio. There are two ways to add a new Web form to a project:

Select Add New Item from the Website menu • Right-click the name of the project in the Solution Explorer, select Add, then select Add New Item

You can use a ....event handler to respond to selections by the user in any list-type control. There is one important consideration, however: the AutoPostBack property must be set to True if you want the user's selection to be detected immediately.

SelectedIndexChanged

You can use the ..property to determine whether users can select only a single item or multiple items from a ListBox

SelectionMode

Selectionmode The two possible choices are Single and Multiple.

The two possible choices are Single and Multiple. In Multiple mode, the user can hold down the ∏ key to select multiple individual items or hold down the s key to select a range of items.

When you set AutoPostBack to ... for a list-type control, users experience a short delay each time they click on the list.

True

In many ways, the... control is similar to the Windows forms ListBox control. It has an Items collection and a SelectedIndexChanged event. You can retrieve the following properties at runtime:

the web page to be retrieved

There are three common things you can do that will let a program move from a Web page we will call the source page to another Web page we will call the target page:

• Place the URL of the target page in the NavigateURL property of a HyperLink control. We discussed the HyperLink control in Section 11.3. • Write code in the Click event handler of a Button, ImageButton, or LinkButton control. In a moment, we will show how to call the Response.Redirect method. • Convert a block of static text to a hyperlink. Select a block of text with the mouse, click the Convert to Hyperlink button on the formatting toolbar (as shown in Figure 11-40), and enter the URL of the target page. Optionally, you can click the Browse button to locate a file within your project, as shown in Figure 11-41.

There are two ways to insert a table when the Design view of a form is active:

• Select Insert Table from the Table menu. When you do so, the Insert Table dialog box appears, letting you set various table layout options (see Figure 11-32). • Select the Table control from the HTML section of the Toolbox window. A basic 3 × 3 table is placed on the form, which you can resize by dragging the handles along its right and bottom sides. A sample is shown in Figure 11-33

Web ListBox control is similar to the Windows forms ListBox control. It has an Items collection and a SelectedIndexChanged event. You can retrieve the following properties at runtime:

• SelectedIndex: returns the index of the selected item • SelectedItem: returns the currently selected item, a ListItem object • SelectedValue: returns the contents of the selected item's Value property

The HyperLink control does not generate any events, but it has three important properties as follows:

• The Text property contains the text shown to the user at runtime. • The NavigateURL property contains the location of the Web page you would like the program to display when the user clicks the link. The property editor has a Browse button you can use to locate Web pages within your project. • The Target property controls whether the new page will appear in the current browser window (the default) or in a separate window. To open in a separate browser window, set Target equal to _blank.

The following Web controls are the ones you are likely to use often. Except where noted by an asterisk (*), all have counterparts among the controls used on Windows forms.

• Button • CheckBoxList* • ImageButton • ListBox • LinkButton • DropDownList (similar to • TextBox ComboBox control) • Label • Image (similar to PictureBox control) • RadioButton • Calendar* • RadioButtonList* • HyperLink*

Web applications written for ASP.NET consist of the following parts:

• Content: Web forms, HTML code, Web forms controls, images, and other multimedia • Program logic, in compiled Visual Basic (or C#) code • Configuration information

The TextMode property has the following choices:

• SingleLine: permits the user to enter only a single line of input • MultiLine: permits the user to enter multiple lines of input • Password: characters typed by the user appear as asterisks

To run a Web application project you have two choices:

• Start without debugging: Press ∏+% to run the Web application without being able to use debugging tools such as single-stepping, stepping into, stepping over, and so on. This is the way that we run all of the Web application projects in this book. • Start with debugging: Press % to run the Web application with the ability to use the debugging tools. (Alternatively you can click DEBUG on the Visual Studio menu, and then select Start Debugging.) When you do this, you will see the window shown in Figure 11-7. Before you can use the debugging tools in a Web application, Visual Studio must modify the application's Web.config file. To continue running the Web application with debugging enabled, select Modify the Web.config file to enable debugging, then click OK. (If you decide at this point that you do not want to use the debugging tools, you can select Run without debugging and click OK.)

The HTML designer offers the following views of a Web page:

Design view: You can visually edit Web pages, using the mouse to drag controls and table borders. This view most closely resembles Visual Studio's editor for Windows Forms projects. • Source view: You use this view to directly edit the HTML source code that makes up a Web form. • Split view: This view displays the page's Design view and Source view in separate panels.

(TYPE OF CONTROL): Controls that let you automatically generate Web pages from database tables.

Three choices for running a web server

• The ASP.NET Development Server (also known as IIS Express) is installed automatically with Visual Studio. It is easy to use and requires no special security setup. • Internet Information Services (IIS) is a professional production tool, which is available as an option with various versions of Microsoft Windows. It must be configured carefully to ensure security against hackers. • A remote Web server is typically available through an Internet Service Provider (ISP) or a corporate Web server. You can copy your application to a remote Web server before running it. You must always have a username and password to publish on a remote server.

Web controls have similar properties to their Windows Forms counterparts. Examples of such properties are Text, Enabled, Visible, Font, BorderStyle, ReadOnly, and TabIndex. The following, however, are a few important differences between Web controls and Windows controls:

• The ID property of Web controls is the counterpart to the Name property of Windows controls. • Web controls have an important new property named AutoPostBack. • Web controls lose their runtime properties when the user moves away from the current page. Special programming techniques, called saving state, are available to overcome this challenge.

In preparation, a computer must be running a Web server. The server waits for connection requests, which occur in two steps:

1. A user running a Web browser connects to the server by opening a network connection and passing a URL to the connection. An example is http://microsoft.com. 2. Using the URL it receives from the user's Web browser, the Web server translates the URL into a physical location within the server computer's file system. The server reads the requested file, now called a Web page. The server sends the Web page over the network connection to the user's computer. The user's Web browser renders (interprets) the HTML. Output consists of text, graphics, and sound.

How web controls are processes

1a user connects to an ASP.NET Web page, a special process takes place, as shown in 2, the Web server reads and interprets the Web controls on the page and executes Visual Basic statements in the application's code-behind file. 3, the server creates a modified Web page consisting of standard HTML tags and controls. 4, the modified Web page is sent back to the user and displayed in the Web browser.
