    Yes.. Using the ASPNET AJAX ScriptManager and UpdatePanel Control will avoid those annoying flickers on the page.. see link below

    </head>

    <body onload="test()">

    Hi,

    Firstly, you need to install 'ASP.NET 2.0 AJAX Extensions 1.0':  http://www.microsoft.com/downloads/details.aspx?FamilyID=ca9d90fa-e8c9-42e3-aa19-08e2c027f5d6&displaylang=en  

    To achieve fetching without refreshing, you can put the button triggering into the UpdatePanel: 

            <asp:ScriptManager ID="ScriptManager1" runat="server" />
                <asp:UpdatePanel runat="server" id="HelloWorldPanel">
                <ContentTemplate>
                    <asp:Button runat="server" id="SayHelloButton" text="Hello, world!" onclick="SayHelloButton_Click" />
                    <br /><br />
                    <asp:Label runat="server" id="HelloWorldLabel" />
                </ContentTemplate>
                </asp:UpdatePanel>

    The available tutorials you can learn about are as below.

    http://ajax.net-tutorials.com/

    http://www.asp.net/ajax/documentation/live/

    Hope it helps.
