Date of Birth field need help

I am creating a web application form. In the form, I need to have a date of birth field. What web controls should I use text box, drop down list or others ?

Hope someone can help me with this !!

Thanks

most commonly noticed option for collecting date of birth is three drop down list (day, month, year), user will be limited to select what's available in the drop-down list. you can also use a text box which require some custom validation code. You can also you a calendar component but it's not common for collecting date of birth.
