ASP / ASP.net postback problems With VB.net 2010 - asp.net

Question

I'm working on a web app and i have the vb.net code working in the web form to only load setting in my controls once. but I'm using a google map control and every time my timer runs that control reloads it setting and wipes out any data i push in. i think i need some help in the asp.net/html side to stop on post back reloading the control.
here is my asp.net/html code.
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<table style="width:100%;">
<tr>
<td style="width: 668px">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<artem:GoogleMap ID="GoogleMap1" runat="server"
DefaultAddress="999 main st, new york NY, 10541"
EnableMapTypeControl="True" EnableOverviewMapControl="False"
EnableReverseGeocoding="True" EnableStreetViewControl="False" MapType="Roadmap"
MaxZoom="25" MinZoom="12" ShowTraffic="False" Zoom="18" Height="380px"
Width="550px" Key="13123123132132132132132123" >
</artem:GoogleMap>
<br />
</td>
<td>
<asp:Button ID="Button1" runat="server" Text="Button" />
<br />
<br />
</td>
</tr>
<tr>
<td style="width: 668px">
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
<asp:Timer ID="tmUpdateAlarms" runat="server" Enabled="False" Interval="30000">
</asp:Timer>
</td>
</tr>
</table>
My Timer Code

gotDeptGUID = foundGUID.DeptGUID
Next
Dim GetAlarms = From r In lqGetAlarms.AlarmDrops
Where r.DeptGUID = gotDeptGUID
Order By r.TimeDate Descending
Select r
If GetAlarms.Count = 0 Then
Exit Sub
End If
Dim myCBTable As New DataTable()

.Add("DateTime", GetType(String))

End With
For Each FoundAlarm In GetAlarms.Take(1)
If Not GridView1.Rows(0).Cells(1).Text.ToString = FoundAlarm.AlarmAddress Then
For Each updateAlarm In GetAlarms.Take(3)
myCBTable.Rows.Add(updateAlarm.TimeDate.ToString, updateAlarm.AlarmAddress, updateAlarm.AlarmType, updateAlarm.AlarmCrossStreets, updateAlarm.AlarmStatus)
Next
With GridView1
.DataSource = myCBTable
.DataBind()
