Multi-line textbox scrolled to bottom?

[Dav]

I need to enable a button when a multi-line textbox has been scrolled to the
bottom. Can anyone tell me if it's possible to do this with client-side
script and/or server code?

Thanks!

Hi,

Thank you for your post.

I think you can use javascript to check the current scroll position of the
textarea (multi-line textbox):

<script language="javascript">
function check()
{
form1.button1.disabled = !(form1.text1.scrollTop ==
(form1.text1.scrollHeight - form1.text1.clientHeight));
}
</script>

You do this check in the onscroll event of the textarea, you can set the
onscroll event in Page_Load:

text1.Attributes.Add("onscroll", "javascript:check();");

Hope this helps. Please feel free to post here if anything is unclear.
