When you write the "(" character after ..Columns.Add the intellisense presents you with two choices because the Add method has two overloads. Take some time to explore the intellisense box that is presented to you here. Read what it says and navigate it. You will see that one of the overloads takes a parameter of type DataGridViewColumn and the other takes two String type parameters (column name and header text). Now try to do what I have explained yourself. As you write more code you will see that the intellisense give you loads of information all the time and helps you complete almost any word you start to write.
