UserControl 类

定义

表示从 ASP.NET Web 应用程序的宿主服务器请求的 .ascx 文件,又称用户控件。Represents an .ascx file, also known as a user control, requested from a server that hosts an ASP.NET Web application. 必须从 Web 窗体页调用此文件,否则将会发生分析器错误。The file must be called from a Web Forms page or a parser error will occur.

public ref class UserControl : System::Web::UI::TemplateControl, System::Web::UI::IAttributeAccessor, System::Web::UI::IUserControlDesignerAccessor

示例

下面的示例SimpleControl中定义的类继承了UserControl类,并可用作 ASP.NET 的代码隐藏类。The class defined in the following example, SimpleControl, inherits the UserControl class and can be used as an ASP.NET code-behind class. TextBox使用Label.TextLabelmyButton_Click Web服务器TextBox.Text控件并定义一个方法,该方法将属性值和两个字符串一起分配给属性。 ButtonIt uses the TextBox, Label, and Button Web server controls and defines a myButton_Click method that assigns the TextBox.Text property value, along with two strings, to the Label.Text property.

重要

此示例具有一个接受用户输入的文本框,这是一个潜在的安全威胁。This example has a text box that accepts user input, which is a potential security threat. 默认情况下,ASP.NET 网页验证用户输入是否不包含脚本或 HTML 元素。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 有关详细信息,请参阅脚本侵入概述For more information, see Script Exploits Overview.

using System;
using System.Web.UI;
using System.Web.UI.WebControls;

public class SimpleControl:UserControl
{

  public TextBox name;
  public Label output;
  public Button myButton;

  public void myButton_Click(object sender, EventArgs e)
  { 
    output.Text = "Hello, " + name.Text + ".";

  }
 
}
Imports System.Web.UI
Imports System.Web.UI.WebControls


Public Class SimpleControl
   Inherits UserControl
   Public name As TextBox
   Public output As Label
   Public myButton As Button
   
   
   Public Sub myButton_Click(sender As Object, e As EventArgs)

      output.Text = "Hello, " + name.Text + "."

   End Sub  

End Class

下面的示例为 .ascx 文件中包含的标记。The following example is markup contained in an .ascx file. 您可以使用SimpleControl在前面的示例中定义的类作为此 .ascx 文件中的标记的代码隐藏类。You can use the SimpleControl class defined in the previous example as a code-behind class for the markup in this .ascx file.

<%@ control inherits = "SimpleControl" src = "SimpleControl.cs" %>

<table style="background-color:yellow;font: 10pt verdana;border-width:1;border-style:solid;border-color:black;" cellspacing="15">
<tr>
<td><b>Enter your name here: </b></td>
<td><ASP:TextBox id="name" runat="server"/></td>
</tr>
<tr>
<td><b><ASP:Label id="output" runat="server"/></b></td>
</tr>
<tr>
<td></td>
<td><asp:button id="myButton" text="Submit" OnClick="myButton_Click" runat="server" /></td>
</tr>
</table>
<%@ control inherits = "SimpleControl" src = "SimpleControl.vb" %>

<table style="background-color: yellow; font: 10pt verdana;border-width:1;border-style:solid;border-color:black;" cellspacing="15">
<tr>
<td><b>Enter your name here: </b></td>
<td><ASP:TextBox id="name" runat="server"/></td>
</tr>
<tr>
<td><b><ASP:Label id="output" runat="server"/></b></td>
</tr>
<tr>
<td></td>
<td><asp:button text="Submit" OnClick="myButton_Click" runat="server" /></td>
</tr>
</table>

注解

UserControl类与扩展名为 .ascx 的文件相关联。The UserControl class is associated with files that have .ascx extensions. 这些文件在运行时编译为UserControl对象,并缓存在服务器内存中。These files are compiled at run time as UserControl objects and cached in server memory.

您可以通过在 Web 窗体页中的另一个 .ascx 文件中声明一个 .ascx 文件来嵌套用户控件。You can nest user controls by declaring one .ascx file in another including the latter in a Web Forms page.

用户控件包含在 ASP.NET Web 窗体页中,并为 Web 开发人员提供了一种简单的方法来捕获常用的 Web UI。User controls are contained in ASP.NET Web Forms pages, and offer Web developers an easy way to capture commonly used Web UI. 它们以类似于Page对象的方式实例化和缓存。They are instantiated and cached in ways similar to Page objects. 但与页不同,不能独立调用用户控件。Unlike pages, however, user controls cannot be called independently. 它们只能从页面或包含它们的其他用户控件中调用。They can only be called from the page or other user control that contains them.

如果要使用代码隐藏技术创建用户控件,请从此类派生。Derive from this class if you want to create a user control using the code-behind technique. 如果使用此方法开发 Web 窗体页,则建议使用此方法。This is recommended if you are developing Web Forms pages using this technique.
