DataGrid with gridTableStyle: how to retrieve data

Question

Hi, I'm sorry for my english...I'm Italian...But i hope there is somebody how could help me...before understand me. I'have a datagrid populated with a dataset builded by hand to support the gridTableStyle wich include a BoolColum and a comboBoxColumn. I noticed that when i tried to retrieve data edited in the datagrid ( myDataGrid.item(row,column) ) I obtain the data from the dataSet and not the one present in the datagrid actually. Is my explanation clear? Could you help me? Thanks CicoBlues
