You would use ASP.NET AJAX[^] to do this. Information tutorials are available at the address I gave you.

I'm assuming that you are using the ASP.NET AJAX library, and that you're attempting to perform your drop-down manipulation on the client side. If that is the case, then you may wish to have a look at the AJAX Control Toolkit's Cascading DropDown[^] control. If I understand your post correctly, it does exactly what you're looking for. As to whether it will improve performance or not, that is difficult to say. As with anything performance related, its much wiser to measure and not to speculate. Hope that helps. :)
