Hmm, Tellalca? What an answer is that?? If you want to comment threads like that, you better do NOT write at all. Otherwise you will be penelized, ok?
Sorry for inconveniances.
Ok, back to the thread`s topic, you can bind data from dataTable, which gets filled from database like this:
DataTable table = new DataTable();
using(SqlConnection sqlConn = new SqlConnection("connString")) //use your conn. string here
using(SqlDataAdapter da = new SqlDataAdapter(@"SELECT Id, Name FROM Person", sqlConn))
comboBox1.DataSource = new BindingSource(table, null);
comboBox1.DisplayMember = "Name"; //colum you want to show in comboBox
comboBox1.ValueMember = "Id"; //column you want to use in the background (not necessary)!
This is about it. Oh yee, rename the sql select query, and use your own names (table and field names) from database.
