TabControl: Tabs with the same form but differente content, is it that way?

[Jvan]

I thougth that TabControl showed the same form but allowing the user to fill the form with different content, isn't it? what is the correct way to use it?

[Blaazen]

TTabControl: same components for all tabs

TPageControl: different components on each tab

[Jvan]

But components have the same values on each tab, I thought the values could be different.

Well you thought wrong! 

Use the Tab events to update the values on the screen .

Its a process that you need to implement.
