我应该使用什么方法或事件预填充扩展的ListView？

I've written an extended ListView in C# WinForms. It's purpose is to show a list of currently running applications using the WinAPI. However, If I try to populate the ListView in the constructor it works when I run the application, but if you try to put the control on any form it will crash VS 2008.I've written an extended ListView in C# WinForm
