gridcontrol devexpress中添加新的自定义列, 条件显示

转自: https://www.it1352.com/1189152.html

using DevExpress.XtraGrid.Columns;
//...
GridColumn columnDiff = new GridColumn();
columnDiff.FieldName = "amountDiff";
columnDiff.Caption = "Diff";
columnDiff.UnboundType = DevExpress.Data.UnboundColumnType.Decimal;
columnDiff.UnboundExpression = "[TransactionAmount] - [AmountDroppped]";
gridView1.Columns.Add(columnDiff);

要有条件地突出显示某些特定行，我建议您使用样式格式条件功能：

using DevExpress.XtraGrid;


StyleFormatCondition condition = new DevExpress.XtraGrid.StyleFormatCondition();
condition.Appearance.BackColor = Color.Red;
condition.Appearance.Options.UseBackColor = true;
condition.ApplyToRow = true;
condition.Condition = FormatConditionEnum.Expression;
condition.Expression = "([TransactionAmount] - [AmountDroppped]) > 400";
gridView1.FormatConditions.Add(condition);
