关于Toolstrip中添加自定义控件DateTimePicker使用说明

如果代码中没有设置缺省属性，则在设计时使用过程中，会出现加不上自定义日期选择控件。以下我在实际代码开发中的组件类源码。此处为.net vb版。

Imports System.Windows.Forms
Imports System.Windows.Forms.Design
Imports System.ComponentModel

'Declare a class that inherits from ToolStripControlHost.
<ToolboxBitmap(GetType(DateTimePicker))> _
<DefaultProperty("getValue")> _
<ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.ToolStrip)> _
Public Class ToolStripDateTimePicker
    Inherits ToolStripControlHost

    Public Sub New()
        MyBase.New(New DateTimePicker())
    End Sub

    Public ReadOnly Property DateTimePickerControl() As DateTimePicker
        Get
            Return CType(Control, DateTimePicker)
