	defaultValue As Object
)

Parameters

The default property for the control.

defaultValue
Type: System.Object

Use this constructor to create a new instance of the ControlValuePropertyAttribute class using the specified property name and default value. The following table shows initial property values for an instance of the ControlValuePropertyAttribute class.

Property

Initial value

Name

DefaultValue

The following code example demonstrates how to apply a ControlValuePropertyAttribute attribute that specifies a default property and value to a custom control. This constructor is called internally by ASP.NET to create a ControlValuePropertyAttribute object that represents the attribute.


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
