Creating a partial class for a form

Question

I would like to create a partial class for my form. I have a lot of events and this is getting messy, so I would like to partition the sections into my own files.

Problem: when I create a partial class of my form, say:

Partial Public Class Form1

End Class

Visual Studio decides I need a different form for this partial class.

Questions:
1. How to create a partial class for a form?
2. If I cannot do this, how can I split all the events in my form into different files?
