Was putting this in a comment but it's easier as a solution ...
Further to SA's solution (which I do not disagree with in any way!)

Are you getting confused between "Columns" and "Cells"?

If a DataGridView has 2 "columns" then in the click event you can capture which "column" was clicked ... it is the Cell index on the row, and is passed in as e.ColumnIndex.

You can still access the other "columns" in the datagrid in the same event, you just have to know their column (Cell) index ...

For example, you could click on any column in the row but check if the first column matches the text ... using your code sample this would look like

C#

private void dataGridView2_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            DataGridViewCell cell = (DataGridViewCell)dataGridView2.Rows[e.RowIndex].Cells[0];

            if (cell.ValueType.ToString() == "Abhinav")
            {
                MessageBox.Show("Right Name");
            }
            else
            {
                MessageBox.Show("Wrong Name");
            }
        }

You cannot "fire" this event, you only can handle it. In .NET, you cannot invoke any event in any class/structure except from the code of the type where the event is declared. This is a .NET fool-proof feature for events; in this aspects, events are different from "regular" delegate instances.

So, in this respect, the question simply makes no sense. Also, the handling of the event you are asking about it totally irrelevant to the number of columns in anything. Maybe, you have some real problem, but you did not describe any.
