AE開發——右鍵TOC中的圖層名顯示屬性表

　　這是我設計的主窗體

　　建立一個窗體，拖入一個datagridview控件，用來展示圖層屬性，Dock屬性設為Fill

　　在主窗體中設定一個OnMouseDown事件

private void axTOCControl1_OnMouseDown ( object sender, ITOCControlEvents_OnMouseDownEvent e )
{
　　//滑鼠右鍵
   if (e.button == 2)
   {
   　　esriTOCControlItem Item = new esriTOCControlItem();
   　　IBasicMap pMap = new MapClass();
   　　ILayer pLayer = new FeatureLayerClass();
   　　object pOther = new object();
   　　object pIndex = new object();
   　　//擷取滑鼠點選的圖層，通過ref參數傳回點選位置所關聯的圖層
   　　this.axTOCControl1.HitTest( e.x, e.y, ref Item, ref pMap, ref pLayer, ref pOther, ref pIndex );

   　　IMapControl2 pMapControl = (IMapControl2)axMapControl1.Object;
   　　IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;
   　　FrmAttribute pFemAttribute = new FrmAttribute( pMapControl, pFeatureLayer.Name );
   　　pFemAttribute.ShowDialog();
   }
}      

以下是屬性展示窗體的源代碼，其中包括了全屏顯示屬性、datagridview自适應form寬度、在表中點選字段名在主窗體中高亮顯示等功能

　　以下是運作效果，通過滑鼠右鍵TOC中的圖層名直接彈出屬性檢視窗體

　　目前正在寫一個隻顯示指定圖層的指定屬性的功能
