Answer 1

Is this a Windows Forms app? If so, try attaching a handler to the TextChanged event of each TextBox on the tab control. When one changes, examine them all, and if they all have data to your satisfaction, enable the next tab and the Next button.

In ASP.NET, you can do something similar with JavaScript using the OnChange client-side event.
