Answer 1

Maybe you have not added references in solution explorer..

I follow the steps below:

GridColumn col=new GridColumn();
col.Caption = "Samples";
col.FieldName = "Samples";
gridView1.Columns.Add (col)

Answer 2

Try the following code

GridColumn column = gridView1.Columns.AddVisible("FieldName", string.Empty);
gridView1.Columns.Add(column);

Answer 3

You should make the columns visible. try the following code:

gridView.Columns.Clear();
for (int i = 0; i < 8; i++){
               gridView1.Columns.Add(new DevExpress.XtraGrid.Columns.GridColumn());
gridView1.Columns[i].Visible = true;
}
