asp.net程序里调用google map api代码
请问有没有人做过在asp.net程序里调用google map api的，类似房产标注是怎么实现的？我需要加大量的标注信息，有什么好的思路？
和asp.net关系比较简单：主要是从后台传递。
先把google map api搞熟悉
下面是api的演示

1、关于传递数据从asp.net到javascript：方式很多.
在webform最直接简单的是 var data = '<%= variableName %>';
2、MS SQL 里面有一个特别的数据字段类型geography，看资料。里面有个功能可以判定一个点是不是在一个多边形里面

GoogleMapForASPNet1.GoogleMapObject.APIKey = ConfigurationManager.AppSettings["GoogleAPIKey"]; GoogleMapForASPNet1.GoogleMapObject.APIVersion = ConfigurationManager.AppSettings["GoogleAPIKeyVersion"]; GoogleMapForASPNet1.GoogleMapObject.Width = "100%"; GoogleMapForASPNet1.GoogleMapObject.Height = Convert.ToDouble(mapHeight)*0.88 + "px"; GoogleMapForASPNet1.GoogleMapObject.ZoomLevel = zoomLevel; GoogleMapForASPNet1.GoogleMapObject.ShowZoomControl = true;
//描绘点 GooglePoint GP1 = new GooglePoint(); GP1.ID = dsZd.Tables[0].Rows[i]["code"].ToString(); GP1.Longitude = Convert.ToDouble(dsZd.Tables[0].Rows[i]["GPSJ"].ToString()); //经度 GP1.Latitude = Convert.ToDouble(dsZd.Tables[0].Rows[i]["GPSW"].ToString()); GP1.InfoHTML = "<a style='text-decoration: none' href='Sjcx_lssj.aspx?zdsim=" + dsZd.Tables[0].Rows[i]["code"].ToString() + "' target=_blank><font size='2'>" + currentValue + "</font></a>"; GP1.ToolTip = "<div style='background-color:#FFF'><font size='2' color=" + color + ">" + titleStr + "</font></div>";//currentValue.Replace("<br>",Environment.NewLine); GP1.IconImage = img; GoogleMapForASPNet1.GoogleMapObject.Points.Add(GP1);
