I suspect this question is answered her in the forums someplace, but not sure what keywords to search for. I have written plenty of custom controls in asp.net for use on my front-end (i.e. contact forms), but now I would ike to develop a custom control that is used for data-entry (with strict validation/formatting requirements) from the back-office. I want anyone that is a content-editor to be able to enter data into these new 'forms' (which will store data into custom tables which will then be used on the front-end via another set of custom controls).

Question is, where/how do I add custom controls to the back-end? Perhaps just a few pointers on what I should be searching for - I can do all the legwork myself, just need someone to point me in the right direction.

Thanks.
