Can someone please help me. I am currently using Sql server Express 5 and c# and I unable to update a Sql datbase table. I have the following windows forms, Form1 and Form3. Form1 is used to show the menu and on the menu is a button that displays a list in a datagrid which is on Form3. On Form3 also is a save button that I want to save any changes that are made to the list.
The problem am having is when I add a row to the list in the table the changes are not showing in the sql datbase when I press the save button. Below is the code I use for Form1 and the code for the 'save button' on Form3'
Thanks for nay help
