以下代码示例演示如何使用 ToolboxBrowsableAttribute 在自定义工具箱浏览器中启用自定义控件的可见性。

' Container for any general design-time metadata to initialize.
' Designers look for a type in the design-time assembly that 
' implements IProvideAttributeTable. If found, designers instantiate
' this class and access its AttributeTable property automatically.
Friend Class Metadata
    Implements IProvideAttributeTable

    ' Accessed by the designer to register any design-time metadata.
    Public ReadOnly Property AttributeTable() As AttributeTable _
        Implements IProvideAttributeTable.AttributeTable
        Get
            Dim builder As New AttributeTableBuilder()

            builder.AddCustomAttributes( _
                GetType(ButtonWithDesignTime), _
                New ToolboxBrowsableAttribute(True))

            Return builder.CreateTable()
        End Get
    End Property

End Class

internal class Metadata : IProvideAttributeTable

    public AttributeTable AttributeTable
    {
        get 
        {
            AttributeTableBuilder builder = new AttributeTableBuilder();

            builder.AddCustomAttributes(
                typeof(ButtonWithDesignTime),
                new ToolboxBrowsableAttribute(true));
