Yep, pretty straight forward (hmm, should there be a hyphen in there?).
Check out the ASP.NET QuickStart to learn how to populate a dropdownlist
from the database, e.g.
http://samples.gotdotnet.com/QuickS...rl=/quickstart/aspplus/doc/webformsintro.aspx
http://samples.gotdotnet.com/QuickS...l=/quickstart/aspplus/doc/webdatabinding.aspx
Try out some samples and tutorials on your own. Once you're familiar with
ASP.NET, create a web form with 3 ASP.NET DropDownList web form controls on
it: make, type, model. In your Page_Load event, have some code like this:
if (!Page.IsPostBack)
{
// this code runs when the page first loads
// populate the make dropdownlist from the database
}
Double click the make dropdownlist in the web designer -- a
make_SelectedIndexChanged method will be generated and assigned to that
dropdownlist control. Add some code to the make_OnSelectedIndexChanged event
to populate the type dropdownlist and clear the model dropdownlist . So when
a user chooses something from the make listbox, the type dropdownlist will
get automatically populated.
Double click the type dropdownlist & add some code to it's
SelectedIndexChanged event to populate the model dropdownlist . So when a
user chooses something from the type listbox, the model dropdownlist gets
populated.
It's pretty easy once you get started. If you ever worked with VB6 forms
you'll find it's pretty similar -- click forms, add code for events, etc.
Good luck!
