Scroll to named hyperlink on page load

How do I cause the web page to scroll to a named hyperlink on page load?

I have an area on the page where a user uses a listbox to select sub-categories until they reach the desired level. Above this listbox I have a "bread crumb trail" of hyperlinks to the higher levels:

CurrentLevel : Rooty > Level 1 > Level 2 (Root, Level 1, Level 2 are hyperlinks back to this page)

[Listbox of subcategories for current selection] (subcategories for Level 2 in this example).

Since this "control" is towards the bottom of the page, when a user selects either the links, or a selection in the list box the page reloads and the page is positioned at the top.

I can get the hyperlinks to work by appending a #category to the link and adding a <a name=category></a> tag.

But how do I accomplish something similar when an entry in the listbox is selected (the listbox has AutoPostBack=true)

Thanks.

Hi sirk_a:

Try this:

    Page.RegisterStartupScript("GoToUsrCtrl", "<scriptlanguage='javascript'>self.location.href='#category'</script>")

on the where the listbox is triggered.  It will jump to where '#category' is placed on your page.

I'm pretty sure that if you use response.redirect, you'll lose your viewstate.  Not sure if that's what you want.

However, if you use  Page.RegisterStartupScript you won't lose your viewstate.  Taking the above example, you can do this:

  Private Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged
        Page.RegisterStartupScript("GoToUsrCtrl", "<scriptlanguage='javascript'>self.location.href='#category'</script>")
    End Sub

allanau20 - Thank you. The RegisterStartupScript was what I needed.


 hismightiness - Since allanau20's worked I did not pursue yours. Although I would need viewstate maintained and I agree that the response.redirect would have lost that.
