private void ListeEntrees_Load(object sender, System.EventArgs e) { Table table = new Table (); dtClient = table.getTable ("Client"); // Get the Client table in a DataTable cboClient.DataSource = dtClient; // Bind the combobox to the DataTable cboClient.DisplayMember = "Client"; // Name of the field to display cboClient.ValueMember = "PK_Client"; // Primary key }The only way I can get this to work is to scan through the DataTable and fill up the combobox with the Add method. Not very pretty IMO and I don't know how to bind the primary key to the values that way.
