在WPF中，您可以将ListView（非DataGrid）绑定到Matrix（交叉表）数据集吗？

Question

是否有可能在WPF中将ListView（不是DataGrid）绑定到事先未知列的Matrix（交叉表）数据集中？

以Northwind数据库为例：下面的简单查询将返回一个可以轻松绑定到listview的已知数据集：

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

为了生成更有意义的报告，我们可以从上面的查询（在报告程序中）运行结果集来生成如下所示的一些内容：

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，可以将这个最终结果绑定到WPF中的ListView或Flowdocument，而无需事先了解结果列？

Answer 1

您可以使用附加属性动态地将列添加到ListView。查看CodeProject上的这篇文章，它完全解释了......

WPF DynamicListView - Binding to a DataMatrix

Answer 2

您可以以编程方式为ListView生成GridView列，并将绑定应用于该列。循环遍历DataSet中的列，并将相应的GridView列添加到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)});
}
