How to create/remove Textbox dynamically at runtime through a button click event -

[wo0ho0]

asp.net? I want to create as well as remove textbox control through coding. Ex. A registration form, user could click on add button to create textbox and fill in more telephone number. when there is a blank textbox (user wanted to delete off the ex. 4th entry number in textbox), i would require to perform a remove the textbox and move the previous textbox up.

Any idea would be greatly appreciated.

P.S: I knew asp could do it.. i am working on .net web app.

Regards.
