Answer 1

If you check the code, you are basically just adding the strings "Code", "Model" and "Itemdescription" to the combobox. I guess you want rather something like:

while (reader.Read())
{
   cbox_order.Items.Add($"{reader["Code"]} {reader["Model"]} {reader["Itemdescription"]}");
}

In this snippet I am using the reader to get values of the columns in the returned row from the DB and then displaying joining those values in a single string that is then added to the ComboBox as an item.

Update

If you know the column names, why not just do this?

public void FillComboBox()
{
    cbox_order.Items.Add("Code").ToString();
    cbox_order.Items.Add("Model").ToString();
    cbox_order.Items.Add("Itemdescription").ToString();
}
