                    gridView2.SetRowCellValue(GridControl.NewItemRowHandle, gridView2.Columns["BS"], rowGridView1["BS"]);
                    gridView2.SetRowCellValue(GridControl.NewItemRowHandle, gridView2.Columns["Repere"], rowGridView1["Repère"]);
                    gridView2.SetRowCellValue(GridControl.NewItemRowHandle, gridView2.Columns["Profil"], rowGridView1["Profil"]);
                    gridView2.SetRowCellValue(GridControl.NewItemRowHandle, gridView2.Columns["Quantity"], quantity.EditValue);

but when I run the code nothing happend,my grid control not binding to any type of data ,How do I solve this problem? , Thanks in advance.

Answer 1

Declare a class that will hold the data for a single Row

class GridRow 
{
   public string BS { get; set;}
   public string Repere { get; set; }
   public string Profil { get; set; }
   public int Quantity { get; set; }
}

then bind the grid's DataSource property to a list of rows like this

this.gridRows = new List<GridRow>();
this.grid.DataSource = this.gridRows;

then to add a new row do this

this.gridRows.Add(new GridRow() { BS = "some value", Repare = "Some value", Quantity = 10});
this.gridView1.RefreshData();
