我创建了个 自定义控件重载了 BackColor 但在使用控件时颜色还是不能改变，下面是我写的 那位高手帮看看呀。

Public Class userdate1

Inherits System.Windows.Forms.DateTimePicker

Protected Overrides Sub OnPaint(ByVal pe As System.Windows.Forms.PaintEventArgs)
MyBase.OnPaint(pe)

'在此处添加自定义绘制代码
End Sub

#Region ""
Public Overrides Property BackColor() As System.Drawing.Color
Get
Return MyBase.BackColor
End Get
Set(ByVal value As System.Drawing.Color)
MyBase.BackColor = value
End Set
End Property
#End Region

End Class
