I was creating a program that will add the value of the first 2 columns in datagridview when you typed it in then the answer will be displayed in the third column... I want to auto update the third column that if I delete the value of one of first two columns the third column will be affected.
Is it possible to update the value of a cell if it already has a value?

Expression column.
Dim dt As New Data.DataTable dt.Columns.Add("No1", GetType(Int32)) dt.Columns.Add("No2", GetType(Int32)) dt.Columns.Add("Sum", GetType(Int32), "No1+No2") datagridView1.DataSource = dt
