gridview单元格编辑添加数据

行号

private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
            if (e.Info.IsRowIndicator)
            {
                if (e.RowHandle >= )
                {
                    e.Info.DisplayText = (e.RowHandle + ).ToString();
                }
                else if (e.RowHandle <  && e.RowHandle > -)
                {
                    e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
                    e.Info.DisplayText = "G" + e.RowHandle.ToString();
                }
            }
        }

声明数据源

private BindingList<InvoiceDetail> DataSource;//发票数据源
//初始化数据源
private void frmAddindent_Load(object sender, EventArgs e)
        {
            this.outTaskListLog.RefreshParent += new RefreshParentHandler((object obj) => { SetForm((OutRequest)obj); });
            DataSource = new BindingList<InvoiceDetail>();
            dvginfo.DataSource = DataSource;
        }

添加新行事件

private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)
        {
            InvoiceDetail invoiceData = gridView1.GetRow(e.RowHandle) as InvoiceDetail;
            invoiceData.Price = ;
            invoiceData.Amount = ;
            invoiceData.Currency = cbDeclaredCurrency.Text;
            invoiceData.Quantity = ;
            invoiceData.QuantityUnit = "PCS";
            invoiceData.OriginCountryCode = "CN";
        }

单元格值，验证，离开事件
