Hi rj1994 ,
Welcome to ASP.NET Forum .
I have a gridview with 8 columns and i need to add another column, which will display the sum (or) product of two specified columns. how can i do that?
Do you use DataGridView control in windows form ? If yes , you could try
DataColumn.Expression Property ,and please refer to below link for how to perform calculation in DataGridView column:
Creating a Calculated Column in the DataGridView Control
Since your question is related to winform , i would suggest you could post to winform forum :
