Hi.
First i want to say this project is awesome :)
My problem is that i have a mobile webviw app that uses positions from a database.
I need to reposition the circle every 10 seconds from the database, but i can only manage this by reloading the whole map.
Is there any way to just move the circle?
Here is my code:
WEB code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" OnLoad="UpdatePanel1_Load" UpdateMode="Conditional">
<ContentTemplate>
<asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick" />
<asp:Label ID="lastupdate" runat="server" />
<div class="map-wrap" style="width: 100%; height: 100px;">
<artem:GoogleMap ID="GoogleMap1" runat="server" MapType="ROADMAP" Width="100%" Height="100px" />
</div>
</ContentTemplate>
</asp:UpdatePanel>
Code Behind:
protected void UpdatePanel1_Load(object sender, EventArgs e)
{
BuildMap();
}
protected void Timer1_Tick(object sender, EventArgs e)
{
//update the update panel every 10 seconds
UpdatePanel1.Update();
}
private void BuildMap()
{
double lat, lng;
string getLocations = "SELECT ChLatCurrent,ChLonCurrent FROM LatLonAuto WHERE UserID = 'paal';";
dt = dbClass.ConnectDataBaseReturnDT(getLocations);
lat = Convert.ToDouble(r["ChLatCurrent"]);
lng = Convert.ToDouble(r["ChLonCurrent"]);
GoogleMap1.Zoom = 15;
GoogleMap1.Center.Latitude = lat;
GoogleMap1.Center.Longitude = lng;
var circle = new GoogleCircle
{
Center = new LatLng(lat, lng),
Radius = 5
};
GoogleMap1.Overlays.Add(circle);
lastupdate.Text = DateTime.Now.ToString();
}
Thanks in advance
Paal
