Examples

A Visual Studio Web site project with source code is available to accompany this topic: Download.

The following code example demonstrates how the Page class is used in the code-behind page model. Note that the code-behind source file declares a partial class that inherits from a base page class. The base page class can be Page, or it can be another class that derives from Page. Furthermore, note that the partial class allows the code-behind file to use controls defined on the page without the need to define them as field members.

using System;

public partial class MyCodeBehindCS : System.Web.UI.Page
{     
    protected void Page_Load(object sender, EventArgs e)
    {

        // Place page-specific code here.
    }

    // Define a handler for the button click.
    protected void SubmitBtn_Click(object sender, EventArgs e)
    {	

        MySpan.InnerHtml = "Hello, " + MyTextBox.Text + ".";
    }
}

Partial Class MyCodeBehindVB
    Inherits System.Web.UI.Page


    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        ' Place page-specific code here.

    End Sub

    ' Define a handler for the button click.
    Protected Sub SubmitBtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyButton.Click

        MySpan.InnerHtml = "Hello, " + MyTextBox.Text + "."

    End Sub

End Class

The following code example shows the .aspx file that corresponds to the preceding code-behind source file.

Important

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.

You must use the @ Page directive and use the Inherits and CodeFile attributes to link the code-behind file to the .aspx file. In this example, the Inherits attribute indicates the MyCodeBehind class and the CodeFile attribute indicates the path to the language-specific file that contains the class.

The following code example demonstrates the single-file page model and how to access the IsPostBack property and the Response property of the Page.

Remarks

The Page class is associated with files that have an .aspx extension. These files are compiled at run time as Page objects and cached in server memory.

If you want to create a Web Forms page using the code-behind technique, derive from this class. Rapid application development (RAD) designers, such as Microsoft Visual Studio, automatically use this model to create Web Forms pages.

The Page object serves as the naming container for all server controls in a page, except those that implement the INamingContainer interface or are child controls of controls that implement this interface.

The Page class is a control that acts as the user interface for your Web application, and as such should be scrutinized to make sure best practices for writing secure code and securing applications are followed. For general information on these topics, see Overview of Web Application Security Threats, Security Policy Best Practices, and Key Security Concepts. For more specific information, see Securing Standard Controls, How to: Display Safe Error Messages, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Introduction to the Validation Controls.
