示例

下面的代码示例演示如何通过将 属性应用于ControlValuePropertyAttribute自定义控件来设置 Name 属性。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Samples.AspNet.CS.Controls
{
    // Set ControlValueProperty attribute to specify the default
    // property of this control that a ControlParameter object 
    // binds to at run time.
    [DefaultProperty("Text")]
    [ControlValueProperty("Text", "Default Text")]
    public class SimpleCustomControl : WebControl
    {
        private string text;

        [Bindable(true)]
        [Category("Appearance")]
        [DefaultValue("")]
        public string Text
        {
            get
            {
                return text;
            }
            set
            {
                text = value;
            }
        }

        protected override void Render(HtmlTextWriter output)
        {
            output.Write(Text);
        }
    }
}

Imports System.ComponentModel
Imports System.Web.UI

Namespace Samples.AspNet.VB.Controls

    ' Set ControlValueProperty attribute to specify the default
    ' property of this control that a ControlParameter object 
    ' binds to at run time.
    <DefaultProperty("Text"), ControlValueProperty("Text", "DefaultText")> Public Class SimpleCustomControl
        Inherits System.Web.UI.WebControls.WebControl

        Dim _text As String

        <Bindable(True), Category("Appearance"), DefaultValue("")> Property [Text]() As String
            Get
                Return _text
            End Get

            Set(ByVal Value As String)
                _text = Value
            End Set
        End Property

        Protected Overrides Sub Render(ByVal output As System.Web.UI.HtmlTextWriter)
            output.Write([Text])
        End Sub

    End Class

End Namespace

注解

ControlParameter在未设置其PropertyName属性的情况下定义对象时，使用 Name 属性确定在运行时绑定到该ControlParameter对象的默认属性。
