将一个对象属性初始化为DataGridView中另一个对象属性的值

Question

我试图将两个对象（列表LedgerEntries和列表BuyerSellers）绑定到单个DataGridView。 LedgerEntry包含Buyer_Seller的属性，我希望最终用户从DataGridView中的组合框（由BuyerSellers通用集合填充）中选择Buyer_Seller，并将LedgerEntries字符串BuyerSeller属性设置为Buyer_Seller字符串Name属性。

目前，我仅使用一个BindingSource，而没有定义自己的列； 它们是根据绑定到DGV的对象自动生成的。 让我有些迷惑的是如何确保将一个对象中的属性初始化为由另一个对象填充的组合框的值。 在此先感谢您的帮助。
