Hi there!

I have a ComboBox (CBBUY) and a DataGrid (DGBUY).  
In the ComboBox, user choose Items Issues of a magazine).  
In the DataGrid appear as Objects all the chosen Items on three columns:  
Item number (nber\_dgc), kind (kind\_dgc) and quantity (qty\_dgc), default value = 1 (qty\_dgc is editable so user can modify it).  
kind\_dgc commands the prices to pay as there is single and double Items.

Questions:

How do I pull out the data contained in DGBUY with updated quantities and then calculate for each row the price to pay depending of the kind\_dgc parameter?  
Should I turn Objects in DGBUY to Strings?  
And how I extract the quantity from each Object in DGBUY?

In the future:  
I wish to use a DataGrid with CellRenderer.  
Where can I find a GOOD Tutorial for this task?

Thank you very much in advance for your answers!

Best regards,
