ASP DropDown causes ViewState to appear in the address bar

If you visit this page in Internet explorer and select a value from the Current Media Releases dropdown at the top right, eventually IE will try to redirect you to an ugly URL containing this line:

__ EventTarget = selArchives & __ EVENTARGUMENT = & __ LASTFOCUS = & __ VIEWSTATE =

The page should only update the string value of the selArchives string.

The dropdown AutoPostBack is set to true and the codebehind is in VB, here is the event handler:

Private Sub selArchives_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles selArchives.SelectedIndexChanged
    Response.Redirect("index.aspx?selArchives=" + selArchives.SelectedValue)
End Sub

Obviously I could just write JavaScript myself, but I would like to find the source of the problem.

Not sure what exactly caused the problem. It looks like it was a combination of several factors.

thanks for the help

First, there are JavaScript errors on your page. Please correct them.

Second, you only see the ugly url when you select a date and hit the go button. But you have a dropdown for auto postback. Turn the button; you don't need that.



There's something entrusted with a button in your codeb. And a dropdown menu as it stops working after multiple uses.

You will need to post the source of your page for more help.

I went to the site. Apart from the javascript errors that show up, it works fine.

The problem only occurs in IE. It works great in Firefox and obviously in Chrome.

Works well for me and IE7 on XP2.

However, there is an expected error while loading the object. $ is undefined.
