Dear Sir I require to Create a New Row in DataGridView with a DropDownList of Items.
After selecting a Item Rate should be filled from Item Master .
After that when I input the Quantity ,  Amount should be calculated automatically.
Also a new row should be generated automatically or by Button Press.

When Save the Button the list of Items with  Quantity  and  Amount should insert into a table.

Select Items    Items           Rate    Quantity  Amount
DropDownList         INJ Charges IM    30    2        60
DropDownList         X-RAY            250    1        250
DropDownList                
                           Total Amount         310
