scrolling to end of text in textbox on ASP.NET page

[DaveC426913]

I'm designing an ASP.NET app and I have a multiline textbox to display a running series of event messages (the same way ws_ftp does). I want the last line to be always in the window, even as the text gets longer and longer.

How can I do this? If this were a VB app, I would use Text.scrolltocaret(), but that is not an option on a webpage textbox control.

I am also open to suggestions about how I can display these messages to the user in some other format (such as a different control.) It would be nice to be able to insert some rich text in my messages, such as colour or bolding on specific lines.

On the server you can use:
Place a literal control add the very end of the HTML page but within the <Form></FORM> tags.

The literal has an id of "MyLiteral"

MyLiteral.Text = "<script>window.setTimeout(""document.getElementById('" & MyTextArea.ClientID & "').scrollTop=10000"",500)</script>"

10000 is just a high number so the textarea scrolls to the end. If it is very large then use a higher number.

That's a whole lot of quote marks in there...

I've gotten this far:

<script language="javascript">
document.frmShowPP.MyLiteral.Text=window.setTimeout("document.getElementById('" & lblStatus.ClientID & "').scrollTop=10000",500)
</script>
...
<asp:Label ID="MyLiteral" Text="" />
Can't get it to recognize MyLiteral in the JavaScript.

Got it. This works:

<script language="javascript">
document.frmShowPP.MyLiteral.Text=window.setTimeout("document.frmShowPP.lblStatus.scrollTop=10000",500)
</script>
