    I have problem. I placed RadNumericUpDown control and set its value to 15 for default.
    Now, I added event for ValueChanged:

    private void FVSdValue_ValueChanged(object sender, RadRangeBaseValueChangedEventArgs e)
           HSdValue.Value = 0.2 * FVSdValue.Value;

    When I start application I'm getting NullReferenceException - the object couldn't be found (Object reference not set to an instance of an object.)

    This happens also for other controls. What am I doing wrong?

    The HSdValue is also RadNumericUpDown, located below the FVSdValue.
