In a scenario when the current culture uses "." as a decimal separator make it possible to have "," as a parsing decimal separator and at the same time have the current culture separator displayed in the control and vice versa.

Make it possible to be notified when the Value has been changed by user interaction by using the Up/Down buttons

Hello,
it would be great if we can have more control about the formatting of the value in the up/down.
I have a scenario where I must use the control to edit a duration in minutes. When the duration is 1 hour or more, it should be displayed as 1:05, for example.
This scenario would be feasible if you had a FormatValue and a ParseValue virtual methods, so we can inherit from the base class and customize completely the display.

The Minimum and Maximum properties could be set automatically to the values set in the Range attribute if it's set to the property that is bound to the Value property of the control.

Currently we're parsing Key.Decimal the same way we're parsing Key.OemPeriod. 
Our clients want to always type the culture decimal separator when pressing the Numpad separator key (del). 

Currently if the client uses a French culture, which decimal separator is comma - pressing the Numpad separator key does nothing.

Workaround: Handling the RadNumericUpDown.PreviewKeyDown method:
private void RadNumericUpDown_PreviewKeyDown(object sender, KeyEventArgs e)
{
	 var num = sender as RadNumericUpDown;
	 if (e.Key == Key.Decimal || e.Key == Key.OemComma || e.Key == Key.OemPeriod)
	 {
		 var textBox = e.OriginalSource as System.Windows.Controls.TextBox;
		 if (!textBox.Text.Contains(num.NumberDecimalSeparator))
		 {
			 textBox.Text += num.NumberDecimalSeparator;
			 textBox.CaretIndex = textBox.Text.Length;
		 }

		e.Handled = true;
	 }
} 

I am in need of a two digit display format using the NumericUpDown control. As I have to display the integer value "0" as "00" in all cases. This is a big draw back as I have to be complient to other systems.
