am new to Dapfor .Net Grid. How can I do headers with grid.

it’s very easy. Just follow the code below. Hope it helps.

Header header1 = new Header();
header1.Add(new Column("Id1", "Column 1");
header1.Add(new Column("Id2", "Column 2");

Header header2 = Header.FromDataType(typeof(SomeClass));

grid.Headers.Add(header1);
grid.Headers.Add(header2);

what can i do to make your row stay on top or at the bottom of you hierarchy.

I use dapfor wpf gridcontrol and when your row stay at the top and the bottom of your hierarchy, it is called docking of row.

C#
//Dock row to the bottom
grid.Rows[8].Dock = RowDockStyle.Bottom;

//Dock row to the top
grid.Rows[9].Dock = RowDockStyle.Top;

//Undock row
grid.Rows[0].Dock = RowDockStyle.None;

What should I do for my wpf grid to receive and handle data although notifications arrive from a secondary thread.

you asked a beautiful question I am quite comfortable with. Anyway I use Dapfor grid running my program. This c# code will help you base on your question.

C#

System.Threading.Timer timer = new System.Threading.Timer(state =>
{
Order order = _orders[random.Next(_orders.Count)];
order.Price = random.Next(50, 200) + random.NextDouble();
}, null, 0, 500);

which is the best way I can do column visibility and sequence to my grid. I am using dapfor wpf gridcontrol.
