1、增加新行用InitNewRow事件,给新行某字段赋值。后结束编辑。

private void grdView_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e) 
{ 
DevExpress.XtraGrid.Views.Grid.GridView view = sender as DevExpress.XtraGrid.Views.Grid.GridView; 
view.SetRowCellValue(e.RowHandle, view.Columns["EnterID"], this.dS_MEnterStoreView.MEnterStore[0].ID); 
this.grdControl.EmbeddedNavigator.Buttons.EndEdit.DoClick(); 
this.grdView.UpdateCurrentRow(); 
}

2、如果进行行验证，就在换行时时行，用grdView_FocusedRowChanged事件

private void grdView_FocusedRowChanged(object sender, DevExpress.XtraGrid.Views.Base.FocusedRowChangedEventArgs e) 
{ 
WsClient.WS_MEnterStore.DS_MEnterStoreView.MEnterDetailRow row = (WsClient.WS_MEnterStore.DS_MEnterStoreView.MEnterDetailRow)this.grdView.GetDataRow(e.FocusedRowHandle); 
if (row != null) 
{ 
if ((this.OperState == Common.Enum.TOperState.UnConfirmNew) 
|| (this.OperState == Common.Enum.TOperState.UnConfirmEdit)) 
{ 
this.InitComboBoxValue(row, row.IsGoodIDNull()?0:row.GoodID, false); 
this.InitBatchComboBoxValue(row, row.IsGoodIDNull()?0:row.GoodID, false); 
} 
} 
}

3、如果需要改变行的某一列的同时改变其它的列用grdView_CellValueChanged事件

private void grdView_CellValueChanged(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e) 
{ 
if (this.grdView.FocusedColumn == e.Column) 
{
if (e.Column == this.colAmount) 
{
}
}
}

4、如果需在离开行的时候需要验证，则用grdView_BeforeLeaveRow事件.
