restore dropList box after back button

[softweb]

I have a dropDown list (combo box) that is bound to a sqlServer table. A selection of an item from the list box redirects the site to another page where it displays an .HTM. When the back button is clicked, the dropDown list does not go back to listIndex = 0, it stays on the selected index item. I tried setting the listIndex to 0 on in the init of the sending .aspx, in selectedINdexChanged of the DL after the redirect .reset and other similar tactics, but can not get that index back to 0. Any ideas

You can set it using javascript
