我使用WPF的DataGrid绑定到自定义类的集合。网格中的XAML使用的AutoGenerateColumns =真，网格创建并填充就好了，但标题是属性名称，如人们所期望的。

I'm using the WPF DataGrid to bind to a collection of a custom class. Using AutoGenerateColumns="True" in the grid XAML, the grid is created and populated just fine, but the headings are the property names, as one would expect.

我试过，指定

<Display(Name:="My Name")> 

从System.ComponentModel.DataAnnotations命名空间，并且没有任何影响。我也试过

from the System.ComponentModel.DataAnnotations namespace and that has no effect. I also tried

<DisplayName("My Name")> 

从System.ComponentModel命名空间，但仍标题不受影响。

from the System.ComponentModel name space but still the headings are not affected.

请问有没有办法来指定列标题用的AutoGenerateColumns选项？

Is there no way to specify column headings with the AutoGenerateColumns option?

推荐答案

使用@马克的建议是该解决方案的开端，但它自己的考虑，自动生成的列仍然有属性名称作为标题。

Using @Marc's suggestion was the beginning of the solution, but taken on it's own, the AutoGenerated columns still have the property names as headings.

要获得显示名称，您需要添加一个程序（在$ C $落后三）处理GridAutoGeneratingColumn事件：

To get the DisplayName, you need to add a routine (in the code behind) to handle the GridAutoGeneratingColumn event:

Private Sub OnGeneratingColumn(sender As Object, e As System.Windows.Controls.DataGridAutoGeneratingColumnEventArgs) Handles Grid.AutoGeneratingColumn
    Dim pd As System.ComponentModel.PropertyDescriptor = e.PropertyDescriptor
    e.Column.Header = pd.DisplayName
End Sub

这是额外的，更好的解决方案是使用ComponentModel.DataAnnotations命名空间，并指定短名称：

An additional and better solution is to use the ComponentModel.DataAnnotations namespace and specify ShortName:

Public Class modelQ016
    <Display(shortname:="DB Name")>
    Public Property DBNAME As String
    ...

OnGeneratingColumn变为：

OnGeneratingColumn becomes:

        Dim pd As System.ComponentModel.PropertyDescriptor = e.PropertyDescriptor
        Dim DisplayAttrib As System.ComponentModel.DataAnnotations.DisplayAttribute =
            pd.Attributes(GetType(ComponentModel.DataAnnotations.DisplayAttribute))
        If Not DisplayAttrib Is Nothing Then
            e.Column.Header = DisplayAttrib.ShortName
        End If

请注意，属性在属性排列的顺序有所不同，所以你必须使用，而不是一个数值参数的GetType（......）......如此有趣！

Note that the order of attributes in the attribute array changes, so you must use the GetType(...) instead of a numeric parameter... Such fun!
