是否可以在 WPF 中将 ListView（不是 DataGrid）绑定到事先未知列的矩阵（跨表）数据集？

以 Northwind 数据库为例：下面的简单查询将返回一个众所周知的数据集，该数据集可以轻松绑定到列表视图：

SELECT  Year(o.OrderDate) AS [Year], Month(o.OrderDate) AS [Month], 
COUNT(o.OrderID) AS [NumOrders]
FROM Orders o 
GROUP BY Year(o.OrderDate), Month(o.OrderDate)
ORDER BY 1, 2

替代文字

为了生成更有意义的报告，我们可能会运行上述查询的结果集（在报告程序中）以生成如下所示的内容：

SELECT  [Year], 
SUM(CASE [Month] WHEN 1 Then NumOrders ELSE 0 END) AS 'Jan',
SUM(CASE [Month] WHEN 2 Then NumOrders ELSE 0 END) AS 'Feb',
SUM(CASE [Month] WHEN 3 Then NumOrders ELSE 0 END) AS 'Mar',
SUM(CASE [Month] WHEN 4 Then NumOrders ELSE 0 END) AS 'Apr',
SUM(CASE [Month] WHEN 5 Then NumOrders ELSE 0 END) AS 'May',
SUM(CASE [Month] WHEN 6 Then NumOrders ELSE 0 END) AS 'Jun',
SUM(CASE [Month] WHEN 7 Then NumOrders ELSE 0 END) AS 'Jul',
SUM(CASE [Month] WHEN 8 Then NumOrders ELSE 0 END) AS 'Aug',
SUM(CASE [Month] WHEN 9 Then NumOrders ELSE 0 END) AS 'Sep',
SUM(CASE [Month] WHEN 10 Then NumOrders ELSE 0 END) AS 'Oct',
SUM(CASE [Month] WHEN 11 Then NumOrders ELSE 0 END) AS 'Nov',
SUM(CASE [Month] WHEN 12 Then NumOrders ELSE 0 END) AS 'Dec'
FROM
( 
SELECT  Year(o.OrderDate) AS [Year], Month(o.OrderDate) AS [Month], 
COUNT(o.OrderID) AS [NumOrders]
FROM Orders o 
GROUP BY Year(o.OrderDate), Month(o.OrderDate)
)t0
GROUP BY [Year]

结果是这样的：

我的问题是，是否可以将此最终结果绑定到 WPF 中的 ListView 或 Flowdocument 而无需事先了解结果列？

您可以以编程方式为 ListView 生成 GridViewColumns 并将绑定应用到它。循环遍历 DataSet 中的列，并将相应的 GridViewColumn 添加到 ListView 中。

var gridView = (GridView)list.View;
foreach(var col in table.Columns) {
   gridView.Columns.Add(new GridViewColumn{
      Header=col.ColumnName, 
      DisplayMemberBinding=new Binding(col.ColumnName)});
}

您可以使用附加属性将列动态添加到 ListView。查看CodeProject上的这篇文章，它准确地解释了......
