Ajax Updatepanel and Manual scroller

mirroras

Hi all !!
I have a difficult issue. I use the Manual Scroller script from dynamicDrive. This script is full working and is cross-browser. The url is for it, is http://www.dynamicdrive.com/dynamici...nualscroll.htm.
I am using a simple example. I have two updatepanels.
The first has a linkbutton inside so when I click it, I show some text in the second updatepanel. I want the scroller to contain the text of second updatepanel.
All the javascript code is inside the second updatepanel But when I run my aspx, i get two different errors: “movedown is not defined” OR “crossobj.offsetHeight is undefined”

If I remove the javascript, the aspx works perfectly.

thanks in advanced

There was a lot of unnecessary code, so I removed it. As you indicated this seems to be a JS problem. I'd like to say told you so, but I won't. I believe there is a problem with calling movedown within the function, I usually use it outside when it is called. I have seen it used inside conjunction with an object so this could be a referencing error, but never had the occasion to use this myself. HTH.
