在gridcontrol devexpress中添加新的自定义列 [英] Add new custom column in gridcontrol devexpress

问题描述

我是Devexpress的新手。现在我需要任何人的帮助才能继续。我在Windows应用程序中有一个gridcontrol。 gridcontrol中的数据使用EntityFramework无限制。里面有很多列。有两列名为AmountDroppped和TransactionAmount。我需要添加另一列来显示这些列之间的差异，如果此自定义列值大于400INR，我想使整行变红。有没有办法在不使用代码隐藏和存储过程的情况下执行此操作。希望可能有一个。

I am new to Devexpress. Now i need help from anybody to go ahead. I have a gridcontrol in a windows application. The Data inside the gridcontrol is unbounded using EntityFramework. There are plenty of columns inside it. There are two columns named AmountDroppped and TransactionAmount. I need to add another columns to display the difference between these columns and i wanna make reddish the whole row if this custom column value is greater than 400INR. Is there any way to do this without using code behind and stored procedure. Hope there might be a one.

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：

To conditionally highlight some specific rows I suggest you use the Style Format Conditions feature:

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);
