Gridview Paging/Scrolling

I have a Gridview with more rows than can be displayed on the screen without scrolling. I added this to the page directive:

MaintainScrollPositionOnPostback="true"

This works great when I click edit/update/delete on a particular row the page keeps the scroll position.

However, the Gridview also has paging enabled with multiple page links. When I change pages the page keeps the scroll position at the bottom of the page.

I would like it to jump to the top of the page when switching between pages. However, I still want it to maintain scroll position on row actions edit/update/delete described above.

Any help would be greatly appreciated!

Solution

Here is the solution I put together:

In the .aspx file add:

<script>
    function ScrollToTop() {
        if (<%=(Scroll)%>) {
            window.scrollTo(0, 0);
        }
    }
</script>

...

<body onload="ScrollToTop()">

...

<asp:GridView ID="GridView1 OnPageIndexChanged="GridView1_PageIndexChanged"

...

In the code-behind .aspx.cs file added:

    protected string Scroll;

    protected void Page_Load(object sender, EventArgs e)
    {
        Scroll = "false";
        Page.MaintainScrollPositionOnPostBack = true;
    }

    protected void GridView1_PageIndexChanged(Object sender, EventArgs e)
    {
        Scroll = "true";
    }
