The .EnsureVisible() method should be the solution you need. However, its effectiveness may depend on how the TextArea is being 
filled.

If it the text is being added by one or more event handlers, the .EnsureVisible() method may not have an opportunity to refresh 
the TextArea's display. You may need to do something like:

[code]
Response.EnsureVisible
Response.Refresh
Wait 0
[/code]

How is the text being added to the TextArea?
