I am using oracle as a backend. I have a table (item_trn) with 3 columns (item_no, no_of_item, value). i have bound this table to a DBgrid. But I want to also display the item_name from table item_master.(item_trn and item_master are related by their item_no). Also I want to update and add data to these two tables using DBgrid. I have one Unbound column in the DBGRID (i.e the item_name coming from item_master) Whenever the new row is invoked the item_name vanishes from the Grid. What could be the problem ?
