Need to format dates in dynamically built WPF DataGrid
提问by FarrEver
We are binding an unknown result set to a WPF DataGrid at run time. Some of our columns are going to contain DateTime values and we need to properly format these date time fields. Without knowing which columns are going to be DateTime fields at design time, how are we able to format the columns at runtime?
我们在运行时将未知结果集绑定到 WPF DataGrid。我们的一些列将包含 DateTime 值，我们需要正确格式化这些日期时间字段。在设计时不知道哪些列将成为 DateTime 字段，我们如何在运行时格式化这些列？
We are using a DataTable's DefaultView to bind to the WPF DataGrid.
我们使用 DataTable 的 DefaultView 绑定到 WPF DataGrid。

Format the binding by StringFormat:
通过StringFormat以下方式格式化绑定：
<DataGridTextColumn Header="Fecha Entrada"
Width="110"
Binding="{Binding EnterDate, StringFormat={}\{0:dd/MM/yyyy hh:mm\}}"
IsReadOnly="True" />
I think it's better than writing code behind pieces of code
我认为这比在代码段后面写代码要好

I figured out how to do this in code...hopefully there is a way to mimic this in XAML. (Please post if you find a working XAML sample.)
我想出了如何在代码中做到这一点......希望有一种方法可以在 XAML 中模仿这一点。（如果您找到有效的 XAML 示例，请发布。）
To accomplish this in code, add an event handler for the Grid's AutoGeneratingColumn event, such as:
要在代码中完成此操作，请为 Grid 的 AutoGeneratingColumn 事件添加一个事件处理程序，例如：
private void ResultsDataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
if (e.PropertyType == typeof(DateTime))
{
DataGridTextColumn dataGridTextColumn = e.Column as DataGridTextColumn;
if (dataGridTextColumn != null)
{
dataGridTextColumn.Binding.StringFormat = "{0:d}";
}
}
}

Hey you can set the locale culture info in the constructor of the WPF form as
嘿，您可以在 WPF 表单的构造函数中将区域设置文化信息设置为
this.Language = XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag);
this.Language = XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag);
Oryou can include the xml markup xml:lang="en-GB"in the window header markup
或者您可以在窗口标题标记中包含 xml 标记xml:lang="en-GB"

<DataGridTextColumn Header="Last update"
Width="110"
IsReadOnly="True"
Binding="{Binding Path=Contact.TimeUpdate, StringFormat={}\{0:dd/MM/yyyy hh:mm\}, Mode=OneWay}" />

I would use a DataTemplate with a DataType of Date or DateTime (depending on which it will come through as). Place a TextBlock in the DataTemplate with a StringFormat in the binding.
我将使用 DataTemplate 与 Date 或 DateTime 的数据类型（取决于它将通过哪个）。在绑定中使用 StringFormat 在 DataTemplate 中放置一个 TextBlock。
Something like this should work (untested)
像这样的东西应该可以工作（未经测试）
<DataTemplate DataType="{x:Type DateTime}">
<TextBlock Text="{Binding StringFormat={0:d}}" />
</DataTemplate>
Or if you want it to apply just in the Grid
或者，如果您希望它仅在网格中应用
<wpfToolkit:DataGrid>
<wpfToolkit:DataGrid.Resources>
<DataTemplate DataType="{x:Type DateTime}">
<TextBlock Text="{Binding StringFormat={0:d}}" />
</DataTemplate>
</wpfToolkit:DataGrid.Resources>
...
</wpfToolkit:DataGrid>

worked beautifuly
工作得很漂亮

The answer of FarrEver, May 11 is good, but by me it doens't function. i still get American mm/dd/yyy instead my German dd/mm/yyyy. So I propose to find the regional settings of computer and use it in StringFormat
FarrEver，5 月 11 日的答案很好，但我认为它不起作用。我仍然得到美国的 mm/dd/yyy 而不是我的德国 dd/mm/yyyy。所以我建议找到计算机的区域设置并在StringFormat中使用
Private Sub DGrid_AutoGeneratingColumn(ByVal sender As System.Object, ByVal e As Microsoft.Windows.Controls.DataGridAutoGeneratingColumnEventArgs)
If e.PropertyType Is GetType(DateTime) Then
Dim dataGridTextColumn As DataGridTextColumn = TryCast(e.Column, DataGridTextColumn)
If dataGridTextColumn IsNot Nothing Then
Dim ShortDatePattern As String = System.Globalization.DateTimeFormatInfo.CurrentInfo.ShortDatePattern
dataGridTextColumn.Binding.StringFormat = "{0:" + ShortDatePattern + "}" '"{0:dd/MM/yyyy}"
End If
End If
End Sub
