Devexpress GridView 单元格输入检验

实现效果

打开设计器 找到CellValueChanged事件

编写代码

        private void gvmain_CellValueChanged(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e)
        {

            string seq = gvmain.GetRowCellValue(e.RowHandle, colQaSeq).ToString();
            QualityInfo item = dataInfo.Find(x => x.Seq.ToString() == seq);
            //匹配是否存在栈板号，不存在则报错，存在则匹配对应id
            if (!_ListPalletNum.Select(b => b.PALLET_NUMBER).Contains(item.pallet_number))
            {

                MessageBox.Show($"该工单不存在 {item.pallet_number}栈板号，请重新填写", "错误提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                dataInfo[e.RowHandle].pallet_number = string.Empty; 
            }
            else
            {
                dataInfo[e.RowHandle].pallet_numberid = _ListPalletNum.First(b => b.PALLET_NUMBER == item.pallet_number).ID;
            } 

        }
