屬性值
控制項的預設屬性。
範例
下列程式碼範例示範如何將 屬性套用 ControlValuePropertyAttribute 至自訂控制項來設定 Name 屬性。
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
備註
ControlParameter在未設定其 PropertyName 屬性的情況下定義 物件時,請使用 Name 屬性來判斷在執行時間系結至 ControlParameter 物件的預設屬性。
