Answer 1

Have you tried use an Update Panel?

<asp:ScriptManager runat="server" />

<asp:UpdatePanel runat="server">
    <ContentTemplate>
       <obout:Grid id="grid1" runat="server"  CallbackMode="false" ... />
       <asp:Timer runat="server" id="Timer1" Interval="10000" OnTick="Timer1_Tick"></asp:Timer>
    </ContentTemplate>
</asp:UpdatePanel>

If the grid already exists, will be the easier solution to you. More information http://www.asp.net/web-forms/tutorials/aspnet-ajax

To automatically refresh your update panel, put a Timer control inside the update panel and set the Interval property with the time in milliseconds you want the Grid refreshed.

You can use AJAX http://www.asp.net/ajax. I recommend you JQuery library http://jquery.com/ for your task.

An example of AJAX useing JQuery (http://api.jquery.com/category/ajax/):

$.get('ajax/test.html', function(data) {
    $('.result').html(data);
    alert('Load was performed.');
});

Please also look in to SignalR with jquery and Jqgrid. Which can push notifications to the browser. Thanks
