Hi.. User Ajax Timer do the same.. You can use UpdatePanel to avoid page refresh.
Ex:
Html part..

ASP.NET

<asp:scriptmanager runat="server" id="ScriptManager1" xmlns:asp="#unknown" />
        <asp:timer id="Timer1" runat="server" interval="50000" ontick="Timer1_Tick" xmlns:asp="#unknown">
        </asp:timer>
        <asp:updatepanel id="UpdatePanel1" runat="server" xmlns:asp="#unknown">
            <triggers>
                <asp:asyncpostbacktrigger controlid="Timer1" eventname="Tick" />
            </triggers>
            <contenttemplate>
                
              // place your gridview here to avoid page refresh for regular interval of 5 minutes

            </contenttemplate>
        </asp:updatepanel>

Interval="50000" is equals to 5 minutes..

Code behind..

C#

protected void Timer1_Tick(object sender, EventArgs e)
    {
        //write code to load and bind data
    }
