ComboBox trouble.
-
Well... I load from database some tables in comboboxes. I want to display only a part of data (i work with adress (state, region, street, cp etc.)) so i use local datasets and load all of it in combobox with arraylist (datasource, displaymember etc.). But i can't just register every street in the country, so for a special place i register all of it, and for all other i want to make possible to register it if it's not registered. So i need to check if i write in combobox some text and then want to insert it in the database if this text is already in the combobox displaymember. So how can i search for an item in combobox by displaymember text?
