Defining default values for subclassed NumericUpDown control

Question

I am subclass my NumericUpDown controls to name xNumericUpDown which appears now on top of toolbox in my IDE.
I would like that my new control set default values differently from original control.
Most important will be DecimalPlaces=2, Minimal=Decimal.MinValue, Maximal=Decimal.MaxValue and Increment=0.

I suppose for that I should make right properties in subclass. So I try as such:

 <DefaultValue(Decimal.MinValue), _
  Browsable(True)> _
Shadows Property Minimum() As Decimal
    Get
        Return MyBase.Minimum
    End Get
    Set(ByVal value As Decimal)
        MyBase.Minimum = value
    End Set
End Property

But this don't work. When placed to form my control have properties of original NumericUpDown.
Minimum=0, Maximum=100, DecimalPlaces=0, Increment=1.

How can I get desired functionality?

I don't know Vb.Net very well but here is c# where you create your own control giving the properties your default values.

public class MyNumericUpDown : NumericUpDown
{
    public MyNumericUpDown():base()
    {
        DecimalPlaces = 2;
        Minimum = decimal.MinValue;
        Maximum = decimal.MaxValue;
        Increment = 1;
    }
}

As I said I don't know vb.Net but I think this is the translation...

Public Class MyNumericUpDown Inherits NumericUpDown
{
    Public Sub New()
    {
        MyBase.New()
        DecimalPlaces = 2
        Minimum = decimal.MinValue
        Maximum = decimal.MaxValue
        Increment = 1   
    }
}

If you don't have a need to use NumericUpDown with constant defaults then creating a custom control wouldn't be of value and you should simply create different objects for each need.

    numericUpDown1 = New NumericUpDown()

    ' Set the Minimum, Maximum, and other values as needed.
    numericUpDown1.DecimalPlaces = 2
    numericUpDown1.Maximum = decimal.MaxValue
    numericUpDown1.Minimum = decimal.MinValue
    numericUpDown1.Increment = 1

You would only use the Shadow keyword to hide implementations in a base class for a class that you derived.
