How to perform sum by row in a datagridview in C #

Good afternoon, I need a help, I have a datagridview that contains a column of Currency type and a column of total Currency. In the Currency Type column I can have up to 3 types of currency, euro currency, dollar currency and real currency. Now I need to make a currency sum. Ex add everything that is euro currency and show in txtboxEuro, then add everything that is dollar currency and show in textboxDolar. How can I do this?
