我们考虑一个通过 ColumnView.CustomColumnDisplayText 事件定制单元格显示文本的示例。 假设网格的视图中包含 CurrencyType 和 Price 列。 如果货币类型等于 0，则以美元格式显示价格。 如果货币类型等于 1，则以欧元格式显示价格。 在 ColumnView.CustomColumnDisplayText 事件处理程序中，获取了 CurrencyType 和 Price 列的取值。 然后根据货币类型设置价格的格式，并把已设置格式的字符串指派到事件的 DisplayText 参数。

CultureInfo ciUSA = new CultureInfo("en-US");

      decimal price = (decimal)view.GetRowCellValue(e.RowHandle, View.Columns["Price"]);
      // Conditional formatting:
      switch(currencyType) {
         case 0: e.DisplayText = string.Format(ciUSA, "{0:c}", price); break;
         case 1: e.DisplayText = string.Format(ciEUR, "{0:c}", price); break;
      }            
   }
