Where should code be placed?

[The Thing]

Hi folks, I'm wondering if it's bad practice in Visual C# to have code in the constructor like so

public Form1()
{

InitializeComponent();

//Some user generated code here like the examples below

method1();

method2();

etc, etc.....

}

or is it better to have methods called, variables declared, etc, in the app's
Form1_Load(...){.....} portion of the code as any code here will run when the form loads anyway.

Thanks for your help.
