I am trying to create an order form and on my DataGridView I want a column for product and a column for price. The DataGridView is not bound to anything, and neither is the combobox in the datagrid for products. I have the combobox get loaded at runtime. I am looking for a way that I can read when the user has selected an item in the combobox and then be able to insert the appropriate price into the price column. All I need to know is the selectedIndex of the combobox, not even the value because the selected index would correspond to the row in the dataset for the price.
