Problem with Autopostback

I have a relatively long page with a number of webcontrols with
"autopostba ck" set to true. The contents/items/datasources of the subsequent
webcontrols are dynamically populated depending on the selection of previous
webcontrols' selected item.

My question is : everytime the user selects an option from a webcontrol, due
to the autopostback being turned on, the page refreshes itself to populate
the subsequent controls. The problem I have is that when it refreshes, it
always ends up showing the top of my very long page.

Are there anyway i could somehow return to the location of the last selected
control that triggered that event or the next control after that? Anchors
does not work here, does it? If not, then how do i do it?

Please help!

To make a workaround in other browsers apart from IE5 and 6, you could
think of inserting a numbered bookmark with each control:
<a name="bookmark0 1">&nbsp</a>

Then, on postback, insert a script to go to the right bookmark:
Sub InsertScriptBlo ck()
Dim jScript As new System.Text.Str ingBuilder()
jScript.Append( "<script language='JavaS cript'>")
jScript.Append( "location.href= '#bookmark01';" )
jScript.Append( "</scr" & "ipt>")
Me.RegisterClie ntScriptBlock(" Bookmark", jScript.ToStrin g())
End Sub

I have a page that works fine. I am trying to optimize the page by overriding some of the Information that is being saved in the hidden VIEWSTATE. If I make the properties of the dropdown False for ViewState and True for AutoPostBack, it does reload the page but does not call the SelectedIndexChanged event. If I put the ViewState to True then it is called. Does this mean that I cannot get that event and deal with it in better code

why need to set autopostback property to be true?? I know autopostback event means to send the form to the server automatically. I tried checkbox, checkbox list, radio button, and radio button list, and they all need to set autopostback property to be true, in order to make the event of the control fires. I know this is the must, but I dont know why. Please advise! Thanks!

Hi, I have a form uses several dropdownlists to narrow a set of criteria. ( This is in turn used to control what is shown on a gridview. ) With each, the user selects an entry and then the next dropdownlist uses that control's selected value to drive what it shows. They're all set to autopostback. Everything works fine except where one of the levels only has one entry. This seems to mess up the next level down and you see the wrong
