Gentlemen:

Does anyone have the answer to these 2 questions?

1. How to sum only those records for the month of March in column 4 in datagrid1 and display it in a textbox3 located in a Tab Control #2 named “Ventas”
2. How to sum ALL records in column 4 in datagrid1 and display it in textbox8 located in a Tab Control #2 named “Ventas”

Thanks
