In this article I will explain with example, how to make a GridView Header fixed (static) on scroll in ASP.Net using jQuery.
Version 2.0 Plugin available. Issues fixed:-
1. Alignment of header columns for GridViews that have more number of columns.
2. Alignment of header columns when external CSS is applied
 
 
HTML Markup
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="up" runat="server">
    <ContentTemplate>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
            <Columns>
                <asp:BoundField DataField="ContactName" HeaderText="Contact Name" />
                <asp:BoundField DataField="City" HeaderText="City" />
                <asp:BoundField DataField="Country" HeaderText="Country" />
                </Columns>
            </asp:GridView>
                <asp:Button ID="Button1" runat="server" Text="Refresh" />
    </ContentTemplate>
</asp:UpdatePanel>
 
 
Applying the Scrollable Grid jQuery Plugin
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="Scripts/ScrollableGridViewPlugin_ASP.NetAJAXmin.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $('#<%=GridView1.ClientID %>').Scrollable({
            ScrollHeight: 300,
            IsInUpdatePanel: true
        });
    });
</script>
 
Above you will notice I have referenced the jQuery and the Scrollable Grid plugin JS files. After that you need to initialize the GridView that you want to make as scrollable.
Parameters
ScrollHeight – Height of the Scrollable DIV
Width – Width of the Scrollable DIV (Optional)
IsInUpdatePanel – This parameter must be set to true when the GridView is inside an ASP.Net AJAX UpdatePanel.
