Postback issue?

Mervin Williams

Postbacks cause a webform to re-display the page at the top. Well, I have a
fairly long form and would like the page display to be re-positioned where
the user clicked the button that caused the postback to occur.

Is there a way to do this?

That is the purpose of SmartNavigation . You can look into this. Be sure to
test your site thoroughly because the SmartNavigation architecture can cause
some problems with a site.

Thanks much!

By the way, is there an article that spells out some of the problems
encountered when using SmartNavigation ?

There might be, but what I know of SmartNavigation is though my own
questions on newsgroups. I have not seen any article that documents the
architecture's behavior.

It may just come through trial and error as you determine what does and does
not work.

Basically, here is how SmartNavigation works. When you turn SmartNavigation
on, the page is rendered with a hidden iframe (visible if you view the
page's source). This iframe is the container for all submit requests. If
you click the submit button, the form data is copied to the iframe and
submitted there. The iframe then returns from the server and some
JavaScript will copy the DOM from the iframe to the main page. That is how
the browser can stay at the same place, it is never reloaded.

If you dynamically create JavaScript that is returned from the server based
on posted conditions, then you may run into problems because the JavaScript
will run in the iframe, not the main page. Also, you cannot turn
SmartNavigation off once it is on because the main page is never refreshed.

I too have had problems with SmartNavigation , I personally would use set
focus to the control you want on postback.

PostBack IFrame src issue

I have a page which has an IFrame on it. The src of the IFrame is a page with a datagrid on it. The Datagrid has bound template columns.

Atlas Postback Problems

The problem comes when someone edits the first box and tabs to the second box. They have enough time to make a quick edit to the second box before the postback completes and then the value in the second textbox is reset to the original value. Is there anything I can do about this? It's really causing...
