Hi. I am trying to answer a question on a course but can't find the info in the course books and as its a marked assignment I can't ask the tutor for help.
The question is this:
If a user adds some new stock using the Stockdialog form, then MainForm's StockBindingSource gets updates with this new stock. If a user then changes the size in one of the sizeComboBox combo boxes, the new stock record is lost. Explain why.
You can assume all forms, comboBox, bindingSources are working.
Any hint, clues, or actual answers would be appreciated.
