如何根据从另一个组合框所做的选择填充组合框

Question

Hie, am using visual studio 2010 C#. i would like to populate my vehicle model combo box based on the vehicle make selected on the top combo box eg if someone select a honda for the make, the second combo box should only populate honda models thus crv, legend, hrv etc. i have also created a 2008 SQL server database that contains two tables, 1 for vehicle makes and the other 1 for model. thanx

Answer 1

You'll have to hook up the change event on your main combobox, and then filter or set the source of the other comboboxes depending on that selection

You could do that with properties, collections, hardcode, linq, and so on, but since you don't have any code, it's a bit hard to point you in a better direction.

Answer 2

  if (ComboVehicleMake.SelectedValue != null && Convert.ToInt32(ComboVehicleMake.SelectedValue) == 27)
    {
        try
        {
        .......// bind the other combobox
