I have a page that has 5-6 HTML Editor Extenders attached to the Text boxes

We hvae a div that pops up on clicking a button.The Last Text box that the HTML Editor Extender is connected to is going to the edit mode.

To avoid this we added a new Text Box that has HTML Editor Extender attached at the end of the page and whose height is very small so that the users cannot see the text box.

Now when i clcik on any button on the page it is redirecting thepage to the bottom of the page where we have that text box.

How to avoid the page being redirected to the end of the page?
