How do you update a dynamically added control? Like for example a textbox, i have textboxes that are created from a database. The ids are created dynamicallyas well. Like a textbox for a name would be like " = "name" & primarykeyid"

Anyway how would i go about updating the text of each textbox? The way i have it currently when it updates it leaves the original ones there but adds new ones with the updated values. How can i get it to just update the existing ones?
