navigate back to same page on select-dropdown selection without clearing down controls?

I have a text box and a drop-down selection on a page, plus a bunch of urls.

Clicking on the urls navigate back to the page with an updated url (for MVC2 functionality). This does not cause the texbox to clear down.

On my dropdown "onchanged" event I call window.location = url; (with url being the pages url with a sortOrder in the query string)... but this causes the pages text-box text to clear down.

Is there any way I can get the drop-down to postback to the page on selection changed and NOT clear down the text box?




What do you mean with "clear down"? Does the dropdown lose it's selected item (e.g. gets reset to a default value)?
