Questions concerning Creating a Master/Detail Form Using Two Windows Forms DataGridView Controls

Hello,

I'm using this walkthrough to learn what I can about the DataGridView control:

Walkthrough

I created a c# Windows Form program and it works real well. I just have some questions.

I'm not sure of why this line is in the code:

this.Load += new System.EventHandler(Form1_Load);

If I leave this in, my program seems to go through the Form_Load event twice.  If I take that line out, the Form_Load only executes once and the program seems to work fine.  Isn't the form supposed to load even if that line is not in the program?  I don't understand the purpose of it.  Am I supposed to leave it in?

Also, the walkthrough does not have an "InitializeComponent();" in it.  Mine does.  Should I put the code in from the walkthrough before the  "InitializeComponent();" or after?

Any help would be gratefully appreciated.

Thanks,
Tony
