One of the most common questions I get is " How to maintain the scroll position-location when a postback occurs in our ASP.NET application? "

A lot of times when  we click on a e.g a button in our application and a postback occurs, our application "loses" its scroll position.

The default behaviour is to go back to the top of the page.

There is a very nice feature in ASP.NET that enables us to maintain the scroll position in ASP.NET.

The name of this attribute is MaintainScrollPositionOnPostBack.

We can set the  MaintainScrollPositionOnPostBack="true"

we can do that within the Page directive e.g

<% Page Language ="C#"  MaintainScrollPositionOnPostBack="true" %>

So now the browser remembers where it was before the post back occured and knows how to keep track of the scroll position.

This is of course achieved with client-side Javascript code that it is injected into the page for us.

So if you go to View -->Source in your browser window, you will see the generated Javascript code.

Hope it helps!!!!
