Is it possible to add text into ColumnHeader of the RowHeader. I put autoincrement into Rowheaders of my DataGridView and I would like to put \"No.\" above that.

So basically you need to display "No." in top left corner?
That area is called TopLeftHeaderCell. It is just like the other DataGridViewCell, you can set its Value property to achieve the task.

dataGridView.TopLeftHeaderCell.Value = "No.";
