How can merge a particular column header in DataGridView C#?

Question

I would like to take a column header text for tow columns. How would you do this? Like this

| FULL NAME |

| first | last

---

I show First & last in one column

Answer 1

I think that's not possible.

Instead try to put your merged data into a Property if you use CustomObjects or into a Column if you use DataSet/DataTable (you can use the Computed Column feature)
