Null Reference error when clicking on NumericUpDown control

[Bharathi]

Hi,

I have used NumericUpDown Control in my application. Clicking
continuously on it would result Null reference error.

System.NullRefe renceException: Object reference not set to an instance
of an object. at
System.Windows. Forms.UpDownBut tons.TimerHandl er(Object source,
EventArgs args) at System.Windows. Forms.Timer.OnT ick(EventArgs
e) at System.Windows. Forms.Timer.Cal lback(IntPtr hWnd, Int32 msg,
IntPtr idEvent, IntPtr dwTime)


I am not understanding why.. Could anyone give me suggestions as how
to avoid this exception.

Thank you,
Regards,
Bharathi
