Examples

下面的代码示例演示如何从 TemplateControl 类派生名为 MyControl 的控件并重写 Construct 方法。The following code example demonstrates how to derive a control named MyControl from the TemplateControl class and override the Construct method. 初始化 MyControl 时,将调用重写的 Construct 方法。When MyControl is initialized, the overridden Construct method is called.

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Security.Permissions;

// The custom user control class.
[AspNetHostingPermission(SecurityAction.Demand,
   Level = AspNetHostingPermissionLevel.Minimal)]
public class MyControl : UserControl
{
    // Create a Message property and accessors.
    private string _message = "No message";

    public string Message
    {
        get { return _message; }
        set { _message = value; }
    }

    // Create an event for this user control
    public event System.EventHandler myControl;

    // Override the default constructor.
    protected override void Construct()
    {
        // Specify the handler for the OnInit method.
        this.myControl += new EventHandler(MyInit);
    }

    protected override void OnInit(EventArgs e)
    {
        myControl(this, e);
        Response.Write("The OnInit() method is used to raise the Init event.");
    }

    // Use the MyInit handler to set the Message property
    void MyInit(object sender, System.EventArgs e)
    {
        Message = "Hello World!";
    }

    // Render the value of the Message property
    protected override void Render(HtmlTextWriter writer)
    {
        writer.Write("<br>Message :" + Message);
    }
}

Remarks

TemplateControl 类是一个抽象类,该类提供 Page 类和 UserControl 类的公共属性和方法。The TemplateControl class is an abstract class that provides common properties and methods for the Page class and the UserControl class. 不会直接创建 TemplateControl 的新实例。A new instance of the TemplateControl is not created directly.

TemplateControl 类定义支持声明性数据绑定表达式的方法:The TemplateControl class defines methods supporting declarative data-binding expressions:

  • Eval 方法用于涉及数据源的数据绑定表达式,如简单的属性或表达式。Use the Eval method for data-binding expression involving data sources, such as simple properties or expressions.

  • 使用 XPath 方法来分析和计算 XPath 数据绑定表达式。Use the XPath method for parsing and evaluating an XPath data-binding expression.

  • 对包含 XPath select 语句的表达式使用 XPathSelect 方法进行数据绑定。Use the XPathSelect method for data-binding against an expression containing an XPath select statement. 结果是实现 IEnumerable 接口的节点集合。The result is a node collection that implements the IEnumerable interface.

有关数据绑定表达式的详细信息,请参阅数据绑定表达式语法到数据库的绑定For more information on data-binding expression, see Data-Binding Expression Syntax and Binding to Databases.
