Problem with ScriptManager.RegisterStartupScript

[Adam Hubble]

Hey,

I am working on an admin interface that has a radgrid with various filter combos above it. To save the user having to scroll down the page after results load I am using this:

ScriptManager.RegisterStartupScript(Page, GetType(Page), "ScrollScript", "Sys.Application.add_load(function_scrollme() {window.scroll(0,800);});", True)

So this works in that the page scrolls to the bottom when the results load in the radgrid, however, if the user then goes back to the top of the page and does something that causes a postback e.g. they select from a combobox that populates another combo using autopostback (ajax way), then the page still scrolls to the bottom - even though I have an ajaxmanager on the page hooked up to the combo boxes.

It seems that the above code seems to fire for every subsequent postback, even controls updating in an ajax way.

Any idea how I can stop this?

Thanks,
Matt

It appears that the problem does not occur if I remove AJAX. So I assume the radscriptmanager must be registering the startup script for EVERY asychronous call. I just want it to register it once for a specific action then go away.

Hi Matt,

Why don't you try the ResponseScripts property of the RadAjaxManager for your purpose?
As if it is more appropriate for your case.

Thanks a lot for replying Sam, that worked perfectly! Shame it dosn't appear to work from ajaxmanagerproxy, but that's no biggy.

Hello Matt,

In case you need to use the ResponseScripts property of the RadAjaxManager on a page you have RadAjaxManagerProxy, then you can try the below code:

RadAjaxManager.GetCurrent(Page).ResponseScripts.Add("alert(1)");

Thus you can get the main ajax manager instance and use it accordingly.
