无法在用户控件的DataGrid RowDetailsTemplate中填充DataGrid行

Question

尝试在我的用户控件中填充 DataGrid 时遇到问题，该用户控件嵌入在父 DataGrid RowDetailsTemplate 中。 子DataGrid （位于用户控件内）应填充从其父DataGrid继承的相关信息。不知何故，它没有按预期工作。但是，当我尝试在我的子用户控件中绑定文本块时，它可以工作！希望有人可以帮助我： - ）

非常感谢

这是我的父DataGrid：

这是我的子用户控件 - 其中包含另一个DataGrid

                     ItemsSource="{Binding}"
                     >

        <Custom:DataGrid.Columns>

Answer 1

这看起来并不正确：

ItemsSource="{Binding}"

或者您的物品实际上是收藏品吗？如果不是，您最好指定内部集合的路径。
