I have two textboxes and when I use the key tab to go from on to the other textbox four events will occur:

Textbox1.Valid
Textbox1.Lostfocus
Textbox2.When
Textbox.2.GotFocus

But if I do the same with mouse the events will occur like this:

Textbox1.Valid
Textbox2.When
Textbox1.Lostfocus
Textbox.2.GotFocus

Why the events occur not in the same order when I select a textbox with a mouse click or the tab key.
How I can change the order of these events?

Thanks in advents for the answer
