server side controls are not displaing in browser

i have installed visual studio .net, windows application is working properly but web application is not working properly. i have created web form which contains some server side controls like textboxes, command buttons and i have set text property at design time but when i am excuting this page. these controls are displying as text on page rather than controls. ASP 3.0 page is working properly that means iis is not supporting serverside controls. so is any additional configuration required? please give solution with explainaton thank you in advance
