嗨
根据您的代码，我认为您应该只在DataGrid编辑模式下看到组合框
因此，请在更改绑定对象的值时检查，确保datagrid处于编辑"模式，然后它才可以工作.按代码执行就可以了.

hi
As per your code i think you should see the combobox in DataGrid Edit mode only
so check while changing the value of binding object, that datagrid is in Edit mode ,then only it will work.codewise it is ok.
