Hi!
I'm looking for an approach for creating server data presentation (input) on client side.
I have a client application (Delphi) and server application ASP.NET.
Server can get different set of data (text, date, true/false etc).
Server can change required data set and than client should react on that change by changing controls for server data presentation.

So the question is: Are there any approaches or existing technologies to support such client-server interaction?

I suppose that it may be done via some intermediate user creating language in some xml format for example. But there are many others questions in such an approach:
How to create control events handling routines? (For example validation, etc)
