1：页面代码：可以添加按钮测试执行SetPushPinsInfo或者SetPolylineInfo函数。

2：后台代码：就是构造向SetPushPinsInfo、SetPolylineInfo一样的js函数而已。
举个例子
string points = "new Array(";
for (int i = 0; i < routes.Tables[0].Rows.Count; i++)
{
DataRow row = routes.Tables[0].Rows[i];
string pid = row["PathID"].ToString();
points += String.Format("new VELatLong({0},{1})", row["Latitude"].ToString(), row["Longitude"].ToString());
points += ",";
}
points = points.Substring(0, points.Length - 1);
points += ")";
this.lbt_showRoute.Attributes["onclick"] = String.Format("SetPolyline({0},{1})", shipmentID, points);
