Hi,
In module#1 I create a new object and write this to a database by clicking a button.
in module#2 I have a datalist which shows the name of all the stored objects.

The first thing in the module#2.page_reload is an "update list" method which fetches information about the stored objects in the database. Also I have a label in module# that displays a timestamp. When I create a new object in module#1 the timestamp in module#2 gets updated. However, the context of my datalist doesn't reflect that I've added a new object. When I click "refresh page" at the top of the browser the change is shown, but I want the change to show as soon as I click the button in module#1. How do I get module#2 to show that the context of datalist has changed?
I guess this has something to do with the communication between client and server... that I have to tell the server to repaint module#2.... but how!?
(I'm very new to asp so please, if you have a suggestion don't suggest doing something too  AJAX-like. I wan't it plain and simple)
Thanx!

Hi Stefan,
Thanks for replying!

Yep, module#1 and module#2 fetches data from the same table in the DB.
I do my timestamp by doing a Sometextbox.text = "updated: " +
 DateTime.Now.ToLongTimeString();
in the page_reload (I'm writing in c#).

I think that I'm onto something which seems to work. I've just discovered the existence of the "onPreRender" Event.
If I execute my databinding in here both module#1's and module#2's controls get updated clientside - which is what I want.

I've been messing a bit around with the dotnetNuke ClientApi and so, also javascript, however, sometimes things seem to work and other times not. As I'm just diving into ASP and DNN, I've decided to wait a bit trying to implement javascripts and client callbacks
 as  I'm often completely blank as to why my stuff isn't working. Hopefully, this will change when I get more into the workings of DNN and ASP.NET
However, If you know a good reference to how the DOM stuff works/functions and how the availability of the DOM tree is associated with page loading, let me know...
