在 ax POS 形式的网格控件中添加一列并显示总计

Question

我正在使用 Devexpress 自定义 AX POS

打开 POS >> 收银任务 >> 取货 >> 转入/转出

在这里，我需要在 gvInventory 中添加一个名为 colDifference 的新列，它显示 orderedQty-Received

的差异我还需要在 gridView

底部显示 diffQty 总数

Answer 1

I need to add a new column in gvInventory named colDifference which shows difference of orderedQty-Received?

我建议您创建一个 Unbound Column in GridView and then calculate your difference at ColumnView.CustomUnboundColumnData 活动。请参阅下面的示例代码片段：

using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.Grid;
using DevExpress.XtraGrid.Columns;

private void Form1_Load(object sender, System.EventArgs e) {
   // ...
   gridControl1.ForceInitialize();

   // Create an unbound column.
   GridColumn unbColumn = gridView1.Columns.AddField("Total");
   unbColumn.VisibleIndex = gridView1.Columns.Count;
   unbColumn.UnboundType = DevExpress.Data.UnboundColumnType.Decimal;
   // Disable editing.
   unbColumn.OptionsColumn.AllowEdit = false;
   // Specify format settings.
   unbColumn.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
   unbColumn.DisplayFormat.FormatString = "c";
   // Customize the appearance settings.
   unbColumn.AppearanceCell.BackColor = Color.LemonChiffon;
}

// Returns the total amount for a specific row.
decimal getTotalValue(GridView view, int listSourceRowIndex) {
    decimal unitPrice = Convert.ToDecimal(view.GetListSourceRowCellValue(listSourceRowIndex, "UnitPrice"));
    decimal quantity = Convert.ToDecimal(view.GetListSourceRowCellValue(listSourceRowIndex, "Quantity"));
    decimal discount = Convert.ToDecimal(view.GetListSourceRowCellValue(listSourceRowIndex, "Discount"));
    return unitPrice * quantity * (1 - discount);
}

// Provides data for the Total column.
private void gridView1_CustomUnboundColumnData(object sender, CustomColumnDataEventArgs e) {
   GridView view = sender as GridView;
   if (e.Column.FieldName == "Total" && e.IsGetData) e.Value = 
     getTotalValue(view, e.ListSourceRowIndex);
}

GridColumn.SummaryItem 属性是一个 GridSummaryItem 对象，它允许您根据汇总计算的值设置字段、应用于字段值的聚合函数和汇总值格式。下图显示了如何分别通过 GridSummaryItem.SummaryType 和 GridSummaryItem.DisplayFormat 属性自定义列摘要类型和显示格式。

示例：

colUnitsInStock1.SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Sum;
colUnitsInStock1.SummaryItem.DisplayFormat = "Sum= {0:n2}";
