in this webform i create dataSet, add tables, add rows to that table and blabla,...
Then i (by clicking on button) redirect to another page where i select an article and all data is written in a dataSet
Then i go back to my first webform where i want to see that data add in my datagrid.

This can simply been done by rebind the datagrid to the OrderTabel (where data is stored in)

But i don't know how to handle with that Page_Load or other command...

Which event do i have to use, so that if my page load on the very first time add tables of part 1
otherwise, when it is load again from redirection it binds my dataGrid (as in my part 2)...

Txs in advance, Scoopie

(i could be it has smth to do with rendering, but i didn't understood as well the published article about this)
