该文是博文http://blog.csdn.net/FlexMapServer/archive/2010/12/09/6064900.aspx，的系列之二，本文是查询POI兴趣点为Point，点击定位，并用图标表示，如下：

查询医院后，点击datagrid中的某行，即某个医院，则定位到地图中，并显示该医院的名称。

托管C#代码如下：

private void QueryDetailsDataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)<br /> {<br /> //MessageBox.Show(QueryDetailsDataGrid.SelectedIndex.ToString());<br /> QueryResultData result = QueryDetailsDataGrid.SelectedItem as QueryResultData;<br /> MessageBox.Show(result.SHAPE);<br /> string[] xyPoint = result.SHAPE.Split(new Char[] { ',' });<br /> double x = Convert.ToDouble(xyPoint[0]);<br /> double y = Convert.ToDouble(xyPoint[1]);<br /> ESRI.ArcGIS.Client.Geometry.MapPoint point = new ESRI.ArcGIS.Client.Geometry.MapPoint(x, y);<br /> MyMap.PanTo(point);<br /> GraphicsLayer graphicsLayer = MyMap.Layers["MyGraphicsLayer"] as GraphicsLayer;</p> <p> //string[] gpsNMEASentence = gpsNMEASentenceArray[i].Split(',');<br /> Graphic graphic = new Graphic()<br /> {<br /> Geometry = point,<br /> Symbol = GlobePictureSymbol<br /> };<br /> graphicsLayer.Graphics.Add(graphic);</p> <p> ESRI.ArcGIS.Client.Symbols.TextSymbol textSymbol = new ESRI.ArcGIS.Client.Symbols.TextSymbol()<br /> {<br /> FontFamily = new System.Windows.Media.FontFamily("Arial"),<br /> Foreground = new System.Windows.Media.SolidColorBrush(Colors.Purple),<br /> FontSize = 12,<br /> Text = result.CN_NAME<br /> };<br /> Graphic graphicText = new Graphic()<br /> {<br /> Geometry =point,<br /> Symbol = textSymbol<br /> };<br /> graphicsLayer.Graphics.Add(graphicText);</p> <p> }
