Server Controls and Page Object Reference

This section provides a quick reference to the key objects described in this chapter. Space constraints prevent us from documenting every object in the .NET framework in this book. For the sake of brevity and conciseness, we include only the most important objects here. For more information on the other objects in the .NET framework, consult the .NET Framework Reference online help file.

Validation controls are covered in Chapter 12.

This chapter covers the Page framework classes in ASP.NET, including the Page object itself, its children, and user-interface controls (HTML controls and server controls). The following sections provide a brief reference to the properties, methods, and events provided by those classes.

AdRotator Class

Member of System.Web.UI.WebControls.

The AdRotator class enables you to display a graphical advertisement on your Web page, changing (or "rotating") the advertisement from a list of graphical URLs. Because they are stored in the form of URLs, the graphics and the pages they link to can reside anywhere on the Web.

The list of advertisements is stored in an XML file. Listing 3.29 shows an example of an XML file.

Listing 3.29 Using the AdRotator Class

<?xml version="1.0" encoding="utf-8" ?>
<Advertisements>
  <Ad>
    <ImageUrl>ad-1.png</ImageUrl>
    <NavigateUrl>http://www.redblazer.com/</NavigateUrl>
    <AlternateText>Advertisement Number One</AlternateText>
  </Ad>
  <Ad>
    <ImageUrl>ad-2.png</ImageUrl>
    <NavigateUrl>http://www.redblazer.com/</NavigateUrl>
    <AlternateText>Advertisement Number Two</AlternateText>
  </Ad>
</Advertisements>

The ImageUrl node denotes which image to display. The NavigateUrl note indicates the page to which the advertisement is linked. The value of the AlternateText node is displayed if the browser has graphics turned off in the browser.

You can have as many Ad elements as you want; the AdRotator will randomly switch between them. To see this, reload the page several times. (To avoid viewing a cached version of the page, be sure you press Ctrl+F5 rather than using the View, Refresh menu command in your browser.)

Note

The standard dimensions for a Web advertising banner is 468 pixels wide by 60 pixels high. You can, of course, use the AdRotator control to display images of any dimensions you want.

You link an XML file with an instance of an AdRotator control by assigning the name of the file to the AdRotator control's AdvertisementFile property. Listing 3.30 shows an example.

Listing 3.30 Using an AdRotator Control to Display Various Advertising Banners in an ASP.NET Page

<%@ Page Language="vb" debug="False" %>
<HTML>
<HEAD>
 <title>ASP.NET AdRotator Control</title>
</HEAD>

<body>
<form id="Form1" runat="server">
 <asp:AdRotator id="AdRotator1" runat="server" Width="468px" 
Height="60px" AdvertisementFile="ads.xml" />
</form>
</body>
</HTML>

As you can see, no event procedure code is necessary to use the AdRotator control (although the control does provide an AdCreated event you can use to intercept and reassign the properties of the advertisement before it is rendered on the page).

Button Class

Member of System.Web.UI.WebControls.

The Button class is the ASP.NET Web control equivalent of the HTML submit and button elements. The class abstracts both elements, adding a number of additional properties and events as well.

Code examples that use the Button object are given throughout this book. Essentially, only two members of the Button object are used with any regularity: the Text property, to display text on the button face, and the Click event, which generates a form submit.

Calendar Class

Member of System.Web.UI.WebControls.

The Calendar class renders a calendar in HTML. In most cases, you'll want to respond to a user selecting a date in the calendar; do this by handling the control's SelectionChanged event.

You can determine whether the check box is checked by inspecting its Boolean Checked property. Setting its Text property assigns a text label to the check box; the TextAlign property determines where the accompanying text label is displayed. Listing 3.32 shows an example.

Listing 3.32 Reading the Checked Value of an ASP.NET CheckBox Server Control

<%@ Page Language="vb" debug="False" %>
<HTML>
<HEAD>
 <title>ASP.NET CheckBox Control</title>
<SCRIPT runat='server'>
 Sub CheckChanged(Sender As Object, e As EventArgs)
  If CheckBox1.Checked Then
   CheckBox1.Text = "Thank you for checking this."
  Else
   CheckBox1.Text = "Check This!"
  End If
 End Sub
</SCRIPT>
</HEAD>

DataGrid Class

Member of System.Web.UI.WebControls.

The DataGrid class enables you to display data in a tabular (row and column) format. Like all data-bound ASP.NET controls, the DataGrid need not be bound to a traditional relational data source; you can also bind to an array or one of the many collection objects provided in the .NET framework.

The HTML output of this control is a table, but the DataGrid class adds a number of useful additional accoutrements such as data paging and formatting.

You can find a number of code examples that utilize the DataGrid control in Chapter 12.

DataList Class

Member of System.Web.UI.WebControls.

The DataList class enables you to display data in a list. The control is similar to the DataGrid control, but instead of displaying multiple categories of data in a tabular (row-and-column) format, the DataList displays a single list of data in a single row. This row can wrap into multiple columns, however.

The various elements of the DataList (header, footer, and items) are divided up into sections and formatted according to templates. Templates are XML sections embedded in the script declaration of the control.

Listing 3.33 provides an example of a DataList control bound to a Hashtable object.

Listing 3.33 Displaying Data in a Hashtable Object in a DataList Server Control

<% @Page language="VB" debug="true" %>
<html>
<HEAD>
<TITLE>ASP.NET DataList Control</TITLE>

<SCRIPT runat="server">
 
  Sub Page_Load(sender As Object, e As EventArgs)
   If Not IsPostBack Then
    Dim h As Hashtable = new Hashtable()
    h.Add ("SF", "San Francisco")
    h.Add ("AZ", "Arizona")
    h.Add ("CO", "Colorado")
    h.Add ("SD", "San Diego")
    h.Add ("LA", "Los Angeles")

    DataList1.DataSource = h
    DataList1.DataBind
   End If
  End Sub
 
  </script>
 
<body>
 
  <form runat=server>

   <asp:DataList id="DataList1" runat="server"
      BorderColor="black"
      BorderWidth="1"
      CellPadding="3"
      Font-Name="Verdana"
      Font-Size="8pt">

     <HeaderStyle BackColor="#000000" ForeColor="#FFFF99">
     </HeaderStyle>

     <AlternatingItemStyle BackColor="#FFFF99">
     </AlternatingItemStyle>

     <HeaderTemplate>

      National League West

     </HeaderTemplate>
        
     <ItemTemplate>

      <%# DataBinder.Eval(Container.DataItem, "Value") %>
      [<%# DataBinder.Eval(Container.DataItem, "Key") %>]

     </ItemTemplate>

   </asp:DataList>

  </form> 
</body>
</html>

Note that, as with all data-bindable objects, you can bind the DataList to a wide variety of objects. We used the Hashtable object in this example for simplicity, but you could bind to an ArrayList, a DataSet, or any other list type.

DropDownList Class

Listing 3.34 shows an example of a DropDownList object that is bound to an ArrayList object.

Listing 3.34 Binding a DropDownList Control to Data Contained in an ArrayList Object

<% @Page language="VB" debug="true" %>
<html>
<HEAD>
<TITLE>ASP.NET DropDownList Control</TITLE>

<SCRIPT runat="server">
 
  Sub Page_Load(Sender As Object, e As EventArgs)
   If Not IsPostBack Then
    Dim list As ArrayList = new ArrayList()
    list.Add ("San Francisco")
    list.Add ("Arizona")
    list.Add ("Colorado")
    list.Add ("San Diego")
    list.Add ("Los Angeles")

    DropDownList1.DataSource = list
    DropDownList1.DataBind
   End If
  End Sub
  
  Sub Pick_Click(Sender As Object, e As EventArgs)
   Label1.Text = "You selected " & DropDownList1.SelectedItem.Text
  End Sub
 
  </script>
 
<body>
 
  <form runat=server>
   <asp:DropDownList id="DropDownList1" runat="server"
      BorderColor="black"
      BorderWidth="1"
      CellPadding="3"
      Font-Name="Verdana"
      Font-Size="8pt">
   </asp:DropDownList>
   <asp:button text="Pick" OnClick="Pick_Click" runat="server" /><BR>
   <asp:label id="Label1" runat="server" />
  </form> 
</body>
</html>

Use the SelectedItem object contained by the DropDownList control to return information about the item selected by the user. The SelectedItem object (an instance of System.Web.UI.WebControls.ListItem) contains a Text property as well as a Value property, enabling you to retrieve both the displayed value and the key associated with the selected value.

In addition to binding the DropDownList object to a list object such as ArrayList, you can also hard-code the list definitions by using <asp:listitem> subelements in the DropDownList definition.

HttpApplication Class

Member of System.Web.

This object is typically accessed as the Application object contained in the ASP.NET Page object.

The HttpApplication class provides a way to store information that has application scope. The Application object contains instances objects such as Request and Response objects (instances of the HttpRequest and HttpResponse classes, respectively) that you can use to access the contents of conventional HTML forms.

HttpServerUtility Class

Member of System.Web.UI.

The HttpServerUtility class provides a variety of utilities for ASP.NET programmers, such as mapping a file request to the file system of the Web server (the MapPath method) and encoding data for use in a URL (the UrlEncode method). It is typically accessed by ASP.NET developers as the Server object contained by the ASP.NET Page object.

As with the HTML target attribute, you can specify the target window to navigate to by assigning a value to the control's Target property; special values such as "_self" and "_new" are recognized by the control.

Page Class

The Page class represents a page request. All controls on a page, as well as utility objects such as Request, Response, Server, and Application (familiar to ASP.old developers), are members of the Page object in ASP.NET.

The page class is the base class from which all ASP.NET pages derive. If you create a code-behind class, it must inherit from this object.

Listing 3.35 shows an example of a Repeater control used to display the contents of the ever-popular Hashtable object. Although you could have used another list control such as the DataGrid or DataList to perform the same work, you can see from the code that the Repeater gives you the capability to embed HTML formatting to have more granular control over the formatting of each row.

Listing 3.35 Using the Repeater Control to Build Customized Output of a Hashtable

<%@ Page Language="VB" debug="true" %>
<html>
 <head>
  <script runat="server">

  Sub Page_Load(Sender As Object, e As EventArgs)
   If Not IsPostBack Then
    Dim h As Hashtable = new Hashtable()
    h.Add ("SF", "San Francisco")
    h.Add ("AZ", "Arizona")
    h.Add ("CO", "Colorado")
    h.Add ("SD", "San Diego")
    h.Add ("LA", "Los Angeles")

    Repeater1.DataSource = h
    Repeater1.DataBind
   End If
  End Sub
 
  </script>
 
 </head>
 <body>
 
  <form runat=server>
 
    <asp:Repeater id=Repeater1 runat="server">
     <HeaderTemplate>
       <table border="0" cellpadding="5" cellspacing="1" 
        bgcolor="#000000">
        <tr>
          <td bgcolor="#FFFF99"><b>Team</b></td>
          <td bgcolor="#FFFF99"><b>Abbreviation</b></td>
        </tr>
     </HeaderTemplate>
       
     <ItemTemplate>
       <tr>
        <td bgcolor="#FFFFFF"> 
          <%# DataBinder.Eval(Container.DataItem, "Value") %> </td>
        <td bgcolor="#FFFFFF">
          <%# DataBinder.Eval(Container.DataItem, "Key") %> </td>
       </tr>
     </ItemTemplate>
       
     <FooterTemplate>
       </table>
     </FooterTemplate>
    </asp:Repeater>
  </form>
 </body>
 </html>

Remember that the Repeater, like all bound controls, can be bound to any list element, not just the Hashtable.

Note, too, that nothing about the Repeater control necessitates outputting data in an HTML table; you can use the Repeater to render data as a comma-delimited list or as a single-column list with line break (BR) elements, for example.
