>>>Hi,

>>>Where do you recommend to make a call to initialize BIZ (typed data set), fill it, and bind controls to the Binding Source? I am reading a book where the examples they have are always in method OnFormLoad. In my tests I use method of the same name as the form class (do I understand correctly that this is equivalent to INIT of VFP?). What is better, OnFormLoad or INIT?

protected override void OnLoad(EventArgs e)
>>{
>>       LoadData()
>>       base.OnLoad(e);

You could swap the two statements around - but be aware of the subtle difference since any active Load event handlers will be called by the base.OnLoad(e) line and whether your data will be available at that point will depend on the order of those two statements.....

No. Maybe it's his own method and he's calling it from elsewhere or has it wired up to the Load event? If you use OnLoad you are overriding the base Form.OnLoad() method.

Pretty much - 'base' refers to the parent class. If you override OnLoad() and don't call the base implementation then the Load event won't be fired. i.e if you could see inside the Form.OnLoad() method it would probably look like this:

public virtual OnLoad(EventArgs e)
{
    if (Load != null)
      Load(this,e);
}
