1. What property do I bind to (or both)? .Text or .SelectedValue ??

You don't bind to anything...

4. The SelectedValueChanged event is firing many times, and it seems to change the value I have selected. How best to deal with this event ... also with the SelectedIndex ?


If you've written your code correctly, and used the proper events, you shouldn't be seeing this problem.

I wonder if you would be able to outline how you would design an implementation to my ComboBox scenario ?

I can't figure out what your ComboBox scenario is!!

Let's see... Are you saying that you have a ComboBox bound to a table that has a list of Names in it? The user picks a Name, then another ComboBox is supposed to fill with some other information, based on the Name picked??

cgai:

I am using VB.NET 2005 and WinForms. I have a bound (dropdownlist) ComboBox who's selection list is based on another field (City) on the Form. The Combo part is a 1-field query (strName) and I am storing the exact same strName field in the database. My selection list is working OK.
