NumericUpDown ValueChanged事件会立即产生影响吗？(NumericUpDown ValueChanged event with immediate consequences?)

 我正在用C＃（.NET 4.0）编写一个小应用程序。 我想在numericUpDown中值更改时触发事件，但似乎当控件失去焦点或有多个更改时，numericUpDown ValueChanged将触发。 
 
 详细说明：我使用对象的属性绑定（OnPropertyChanged）numericUpDown，以便立即反映更改。 但我还需要使用这个新更改的numericUpDown值来计算某些内容（全局/与对象无关）。 但是如果我使用ValueChanged事件，那就太晚了。 
 
 简短的介绍： 
 
 我需要一个与OnPropertyChanged具有类似功能的事件。 
 
 我能做什么？ 
 
 编辑：在ValueChanged事件处理程序中，我对对象进行了一些计算，但是已更改的值尚未提交给object属性，因此我认为ValueChanged事件滞后。 
 
 感谢您的帮助。 

I'm writing a small application in C# (.NET 4.0). I want to fire an event when value changes in numericUpDown, but it seems that numericUpDown ValueChanged fires when control loses focus or when there are multiple changes.
 
Long description: I am binding (OnPropertyChanged) numericUpDown with a property of an object, so that the changes are reflected immediately. But I also need to calculate something (global / not related to object) using this newly changed value of numericUpDown. But if I use ValueChanged event, it fires too late.
 
Short description:
 
I need an event with similar functionality to OnPropertyChanged.
 
What can I do?
 
EDIT: In ValueChanged event handler I did some calculations on the objects, but the value that has changed wasn't yet committed to the object property, thus I thought that the ValueChanged event was lagging behind. 
 
Thank you for your help.
