I am building a asp.net page dynamically.

The controls are laid out in advance, I then read a dataset and apply text to labels with corresponding text boxs.

The issuse I am running accross is that based on the label text, the input migh tbe that of a phone, or zip code or just a required entry.

Is there a method of extending or changeing the properties of the webtextedit box to that of a webmaskedit. This is all donw inthe code behind when the pageloads.
