Hi,
which Form event is triggered first during application startup? I need
to load data from a database before RowEnter event of a DataGridView
comes to life. I've put the loading code into Form_Load, but that is not
good enough, because RowEnter is triggered sooner. Hence, an exception
is raised when I try to work with the DataSet, which does not contain
any tables yet.

Thanks for any help.

With regards
Paul Jones.

You may want to consider calling a function from the constructor,
before InitializeComponent is called.

Justin, thanks for replying...

I'm kind of a newbie, could you please tell me how should I do it
precisely? I piece of code would be great.

Thanks for any further assistance.

All you need to do is place the code inside the Form constructor, like

public Form1()
{
    this.MyDataSet = new DataSet();
    ... code ...

    InitializeComponent();
}

That code will execute before any items inside that form even exist.

Thomas, thank you very much... I'll try it. Just one other question, can
I use MessageBox.Show() here before InitializeComponent() is executed?

Thanks.

Why don't you try it? ;)
It should work just fine, I've done it in Main() (Program.cs), works
just fine.

Well, because I'm not able to try it now... :) Nevertheless, you're
right, that was not a good question...
