怎样在pageLayout控件中实现地图属性显示？

<P>怎样在pageLayout控件中实现地图属性显示？</P>
<P>我尝试了在mapcontrol 控件中能够用Identify,IArray实现，可是以下代码在pageLayout中parray总被赋空值。</P>
<P>ESRI.ArcGIS.Geometry.IPoint pPoint = new ESRI.ArcGIS.Geometry.PointClass();<BR>   pPoint = axPageLayoutControl1.ActiveView.ScreenDisplay.DisplayTransformation.ToMapPoint(e.x,e.y);<BR>   pPoint.SpatialReference=this.axMapControl1.SpatialReference;<BR>  <BR>   ESRI.ArcGIS.Carto.IIdentify pIdentify = new ESRI.ArcGIS.Carto.FeatureLayerClass();<BR>   ESRI.ArcGIS.esriSystem.IArray pArray = new ESRI.ArcGIS.esriSystem.ArrayClass();<BR>   ESRI.ArcGIS.Carto.IFeatureIdentifyObj pFeatIdObj = new ESRI.ArcGIS.CartoUI.FeatureIdentifyObjectClass();<BR>   ESRI.ArcGIS.Carto.IIdentifyObj pIdObj = new ESRI.ArcGIS.CartoUI.FeatureIdentifyObjectClass();<BR>   <BR>   ESRI.ArcGIS.Carto.IMap pMap = new ESRI.ArcGIS.Carto.MapClass();<BR>   pMap = axPageLayoutControl1.ActiveView.FocusMap;<BR>   ESRI.ArcGIS.Carto.ILayer pLayer = pMap.get_Layer(0);<BR>   pIdentify = pMap.get_Layer(0) as ESRI.ArcGIS.Carto.IIdentify;</P>
<P><BR>  <FONT color=#ff0000> pArray</FONT> = pIdentify.Identify(pPoint) as ESRI.ArcGIS.esriSystem.IArray;<BR>   if (pArray != null)<BR>   {<BR>    pFeatIdObj = pArray.get_Element(0) as ESRI.ArcGIS.Carto.IFeatureIdentifyObj;<BR>    pIdObj = pFeatIdObj as ESRI.ArcGIS.Carto.IIdentifyObj;<BR>    pIdObj.Flash(axPageLayoutControl1.ActiveView.ScreenDisplay);<BR>    MessageBox.Show("Layer:" + pIdObj.Layer.Name + "/n" + "Feature:" + pIdObj.Name);<BR>   }<BR>   else<BR>   {<BR>    MessageBox.Show("无");<BR>   }</P>

<P>建议用ISpatialFilter 来查询</P><img src="images/post/smile/dvbbs/em01.gif" />
