How to make SFComboBox display error message that comes from error provider

Hi, I can't figure out how to make SFComboBox display error message that comes from error provider. 

I have SFComboBox on my form called sfCboId and error provider called epPurchaseOrders.
After I added error provider, few new properties appeared in the combo box property window in form designer. One of these properties is "Error on epPurchaseOrders". It's a text property and when I type something there, it just displays error icon and exactly the text I typed. But when I add native winforms controls (textbox, combobox, etc) that are bound to the same field, they display actual error message which is brought by IDataErrorInfo via epPurchaseOrders.

So how can I achieve the same behavior for SFComboBox? It doesn't matter if programmatically or via form designer (I use Visual Studio 2019).

Thank you.

While experimenting further I have found the resolution - selectedvalue of my combobox was originally bound to object property. When I did the following, it started working:
- added bindingsource to the form 
- bound bindingsource to my object
- bound selectedvalue of combobox to bindingsource's property (not to object's property directly).
