Escape/override MaintainScrollPositionOnPostBack C#

At the very first the requirement was to set position in same from where I pressed the button. So I set MaintainScrollPositionOnPostBack = true from c# or from page property.

After that I realized that, there is button I have to go to top after postback.

Now the problem is, I have to escape the MaintainScrollPositionOnPostBack only for that button.

What to do?

I searched a lot, tried a whole day with Javascript/JQuery and also from C#, but fails.

At last I did a little research on it. Actually the logic is the for MaintainScrollPositionOnPostBack to store the position in two JS variable, '__SCROLLPOSITIONX' and '__SCROLLPOSITIONY'.

Now I started to crack the code like that.

protected void BtnAddItems_Click(object sender, EventArgs e)
   {
       string script = @"<script language=javascript>
       var scrollX = document.getElementById('__SCROLLPOSITIONX');
       var scrollY = document.getElementById('__SCROLLPOSITIONY');
       if(scrollX != null && scrollY != null)
       {
         scrollX.value = 0;
           scrollY.value = 0;
           }
           </script>
           ";
       Page.ClientScript.RegisterStartupScript(Page.ClientScript.GetType(), Page.ClientID, script, false);
   }


And it succeed!!!!!
