1 axTOCControl有关
1.1 右键弹出菜单
using ESRI.ArcGIS.Controls;
using ESRI.ArcGIS.Carto;
private void axTOCControl1_OnMouseDown(object sender, ESRI.ArcGIS.Controls.ITOCControlEvents_OnMouseDownEvent e)
        {
           
            if (e.button != 2)   //响应右键点击事件
                return;
            System.Drawing.Point p = new System.Drawing.Point(e.x, e.y);
            System.Drawing.Point pPoint = axTOCControl1.PointToScreen(p);

            contextMenuStrip1.Show(pPoint.X, pPoint.Y);


        }
1.2 axTOCControl1中隐藏图例
private void HideLayerInfo(ILayer layer)
        {
            ILegendInfo pLInfo;
            pLInfo = layer as ILegendInfo;
            ILegendGroup pLGroup;
            int i;
            for (i = 0; i < pLInfo.LegendGroupCount; i++)
            {
                pLGroup = pLInfo.get_LegendGroup(i);
                pLGroup.Visible = false;
            }
            axTOCControl1.Update();
        }
1.3 axTOCControl1中显示图例
  private void ShowLayerInfo(ILayer layer)
        {
            ILegendInfo pLInfo;
            pLInfo = layer as ILegendInfo;
            ILegendGroup pLGroup;
            int i;
            for (i = 0; i < pLInfo.LegendGroupCount; i++)
            {
                pLGroup = pLInfo.get_LegendGroup(i);
                pLGroup.Visible = true;
            }
            axTOCControl1.Update();
        }

1.4 axTOCControl1刷新图例
axTOCControl1.Update();
1.5 axTOCControl1选中某个图层
axTOCControl1.SelectItem(layer, null);
1.6 axTOCControl1图层拖动
axTOCControl1.EnableLayerDragDrop = true;
1.7 axTOCControl1获得当前的图层
private void axTOCControl1_OnMouseDown(object sender, ESRI.ArcGIS.Controls.ITOCControlEvents_OnMouseDownEvent e)
        {

            esriTOCControlItem item = esriTOCControlItem.esriTOCControlItemNone;
            IBasicMap map = null; 
            ILayer layer = null; 
            object other = null; 
            object index = null;

            //Determine what kind of item has been clicked on
            axTOCControl1.HitTest(e.x, e.y, ref item, ref map, ref layer, ref other, ref index);
            MessageBox.Show(layer.Name);
}
