Derived class from Button

I derived a class from System.Windows.Forms.Button, named Cell.
I created Button, and than changed it be a Cell.
It was complied, and run.
BUT, if I change anything in the form, my cell is removed from the code.
What can I do?

do you have a sample snippet of the code that you are trying.
avoid writing in Initialize method, coz sometimes VS.NET editor with remove code , I have seen that

;)
