title: check combobox selected index changed in datagridview in vb.net
body: <p>Hi all I'm developing an accounting software for a small business where I'm facing an issue in invoice part where user is going to put item for buy / create invoice here I'm fetching data from items table to display as a combobox in data grid view but I want to fetch amount and item code when user will select a item in combo box also I want to hide the selected item from the next row so user is not able to select same item again and again. I had tried all possible solution available on internet mostly are for normal combobox or else in the c# which i'm not able to understand.</p>
