Declarative vs. Advanced DataSource

[Jason Bourdette]

New be here. Just trying to get my feet wet and make sure I understand the different databinding techniques for the RadGrid.

So clearly I understand that Simple Data binding is only good if your NOT doing filtering, sorting, paging. Which of course I'm doing.

So between advanced and declarative I could not really find a comparison. Is one method preferred over the other. Any performance gains by using one over the other.

A some what sperate question but related:
Before switching to telerik, on my web page I had an ASP.NET timer control that was set to fire my databinding method after half a second. This way the web page and layout could fully load to the user, and the user would just see an ajax "loading..." type message while the grid data loaded.  Is this at all similar to the NeedDataSource method? Does the web page render before the NeedDataSource method fires? If not how could I achieve this same thing using the telerik framework?

Thanks
Jason

I did some more reading and i think i pretty much have my answer.

Seems like declarative is good a quick mock up but any real world app would probably want to use advanced mode.

Also found a post already on the forum that perfectly describes Late binding to a RadGrid.
