Try to make an editable datagrid in wpf.
Figured out how to bind data to datagrid and edit them.
Figured out how to bing enum to combobox in datagrid with objectprovider by this answer.
However when i try change my program locale at runtime, the combobox items won't change it's content with locale resources.
Is there some way to make the combobox be able to bing an enum and able to locale with dynamic resources?
Here's my code:
