Partial Rendering without Ajax?

[Guest]

I am trying to figure out how to do a postback that updates only changed
controls without having the entire page refresh and flash on the screen.
Seems to me this was available in ASP.NET 1.1, but I can't remember how it
was done (I did it in another project but can't remember how).

I do not want to use Ajax.

I tried a search but got so many hits related to Ajax that I gave up.

Thanks

It is probably SmartNavigation you are referring to.

Hey Teemu. Howsta nappa?

What is SmartNavigation?

 

[Teemu Keiski]

You can set SmartNavigation="true" on Page directive. It's the previous
mechanism (in ASP.NEt 1.x, obosolete but exists in v2.x) to prevent refresh
on postbacks, and to keep scroll positions etc.

Tried that. Now I get Stack Overflow on Line 0 if I click the submit button
more than once. This message comes after all the events in the page have been
fired, so I'd say the feature is not so well supported any more. Am I missing
something?

Nope, SmartNavigation didn't (doesn't) work out well so, best way *really*
is to stick to ASP.NET Ajax or some commercial Ajax library. In ASP.NEt 2.0
you certainly can use client callbacks (call backs to server-sise code) too,
in case you just want to deal with the client-side yourself

In ASP.NET 2.0 scroll position can be kep by using
MaintainScrollPositionOnPostBack="True" to @Page directive. Focus can be set
with SetFocus method of the Page.

You work a long day!

I figured out why I was getting the error. I also had
MaintainScrollPositionOnPostBack="True" set in the page. When I removed that,
the stack overflow went away. Apparently IE is not too happy with both turned
on. Thanks!
