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).
