Is the id not transmitted?

Question

firebird

In combobox select I send the name of the country and its ID. When it comes to saving, it is not the id itself that is passed, but "COUNTRY_ID" (a word). PS: The name of the country in the combobox is displayed normally

Answer 1

reader2["COUNTRY_ID"].ToString() not?

Answer 2

Make sure COUNTRY_ID is a property, not a field. For two-way it is better to take some kind of ObservableCollection thread.
The pressed box can be taken like this (not by name, if you rename it will work)
var cmb = sender as ComboBox;

Answer 3

Too suspicion that COUNTRY_ID not property.
