绑定到datepicker在datagrid rowdetails

我有一个数据网格。当单击行时，会显示rowdetails。在rowdetails中，datagrid旁边的另一个datagrid是DatePicker。绑定到datepicker在datagrid rowdetails

所以主DataGrid有一个自定义对象的集合。当单击一行时，子数据网格将绑定到selecteditem.Funds（另一个列表）（如下所示的代码）。 selectedItem也有一个datetime属性，我想绑定到我的DatePicker，但我无法让它工作。

我使用下面的一行，

<DatePicker SelectedDate="{Binding SelectedItem.DateEffective2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>

我认为（也许是错误的，因为日期选择在rowdetails我将能够绑定到selectedItem属性，你猜我错了？

<DataGrid Grid.Row="1"

在DataContext为的DatePicker应该已经是的SelectedItem，尝试将其更改为： –

谢谢，现在的作品！如果你把你的评论作为回答高兴地标记为正确 – mHelpMe

在DataContext为的DatePicker应该已经是的SelectedItem，尝试将其更改为：

<DatePicker SelectedDate="{Binding DateEffective2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>

ItemsSource="{Binding SelectedItem.Funds, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"

为：另外，你的子DataGrid的ItemsSource时，可以从简化

ItemsSource="{Binding Funds}"
