因此，对于每个“稳定性级别”“windspeed类”对，windrose实例保留一个包含37个值和一个额外浮点值的数组

我不知道如何做两件事：

A. 我不知道如何创建这个表DataGrid。我希望能够更改根据所选NumberOfDirections动态生成的行数。 选定的NumberOfDirections还确定了步进360度除以两个后续行之间的NumberOfDirections

B 在x:Name=WSClass的网格中，我希望能够将_average数组的项绑定到文本框，以便每个文本框对应于表示风速级别的某个RadioButton 具有值_平均[选定的稳定性][相应单选按钮的风速]

2013年11月22日编辑： 我问了一个关于如何实现这一目标的简单机制的问题。 用户已经回答了。由于我不能要求他在这个问题的背景下重写他对我问题的解决方案，我决定正确回答这个问题的唯一方法就是回答我自己的问题

警告：长柱

模型类： 查看模型类： 风向： 当我创建一个数据类型类来保存我需要在datagrid行中显示的所有信息时

所以

它实现INotifyPropertyChanged接口 为要在datagrid中显示的每个列实现一个属性 AddModifyWindroseDialogViewModel: 视图中的组合框有一个ObservableCollection，StabilityLevel WindspeedClass的每个组合都有一个ObservableCollection。因为用户必须能够一次编辑所有这些信息，所以我们为其创建了一个锯齿状数组

基本上，我们的想法是，基于2个属性的值，这两个属性决定了稳定性水平和风速等级，我们通过第三个属性返回适当的ObservableCollection。如果用户更改整个windrose的方向数，我们将调用私有方法UpdateFilteredItems。拥有ObservableCollection实际上允许我们将其绑定到DataGrid的ItemsSource，然后自己定义DataGrid的列，并将WindroseWindDirection的各个属性绑定到这些列
