        set
        {
            // Provide implementation.
        }

Public Class customeditablebox

            Events.AddHandler(EventCustomTextChanged, value)
        End AddHandler

        RemoveHandler(ByVal value As EventHandler)

        End RaiseEvent
    End Event

    Public Property Text() As String _
      Implements System.Web.UI.IEditableTextControl.Text
        Get
            ' Provide implementation.
            Return String.Empty
        End Get
        Set(ByVal value As String)
            ' Provide implementation.
        End Set
    End Property
End Class

備註

當 TextChanged 屬性在貼文到伺服器之間變更時 Text ，就會發生此事件。 您可以在 或 控制項中找到 TextBox 這個事件的實作 ListControl 。
