使用Reimer ASP.NET控件的Google Maps V3 [英] Google Maps V3 Using Reimer ASP.NET Control
问题描述
我正在使用reimers.dk的ASP.NET控件，并且能够查看地图，添加缩放/平移控件.在地图内平移和缩放都可以正常工作.我的问题是使地图以ASP.NET发送的点为中心，例如单击按钮即可.地图没有任何影响或改变.感谢您提供任何帮助.
I'm using the ASP.NET control from reimers.dk and I was able to view the map, add zoom/pan controls. Panning and zooming work fine from within the map. My problem is getting the map to center on a point sent from ASP.NET, like from a button click. There is no effect or change to the map. Any help with this is appreciated.
以下是页面和代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<%@ Register assembly="Reimers.Google.Map" namespace="Reimers.Google.Map" tagprefix="Reimers" %>

</Reimers:Map>

public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Map1.MapControls.Add(new Reimers.Google.Map.Controls.ZoomControl());
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Map1.SetCenter(new Reimers.Google.Map.LatLng(27, -82));
}
}
我也尝试了没有此控件的js.我得到了类似的结果.
I also tried with js, without this control. I got similar results..
先谢谢您.
推荐答案
我花了一些时间才弄清楚这一点.这段代码对我来说可以在Page_Load方法中设置中心:
It took me some time to figure this out. This code works for me to set the center in the Page_Load method:
LatLng laln = new LatLng();
laln.Latitude = 65;
laln.Longitude = -19;
Map1.Center = laln;
