Just to add to the last post.
What i am trying to eventually achieve with this is a tooltip of validation errors. So I have radtextboxes etc which ajax back and validate. If there is a problem with the validation the error is stored in session, the codebehind then shows the tool tip manager (which is using a user control
ctrl = Page.LoadControl("ToolTip.ascx");
This user control then reads from the session and displays a lit of all validation errors on the page. I want the tooltip to scroll up and down the page as the user does. What would be nice is if i could also put a link in the user control against the error. When the user selects the link it takes the user to where the validation error is on the page.
I realise I might trying to take the control a little to far but should this be feasible.
