右键图层打开属性表

TOCControl控件使用的是用伙伴控件中的数据地图，它控制图层是否在伙伴控件空显示以及和伙伴控件在符号上保持一致，TOCControl为用户提供了一个交互式的环境，如果TOCControl控件的伙伴控件是MapControl控件，当我们将TOCControl控件中图层删掉是，MapControl控件中相应的图层也会被删掉。
TOCControl最常用的就是右击它，然后弹出一个快捷菜单，进行操作。

鼠标右击，弹出一个菜单，选择之后弹出一个属性窗体

 

 代码如下：

namespace openAttributeTable
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
         
        private void Form1_Load(object sender, EventArgs e)
        {
            OpenFileDialog open = new OpenFileDialog();
            string fileName = string.Empty;
            if (open.ShowDialog() == DialogResult.OK)
            {
                fileName = open.FileName;
            }
            axMapControl1.LoadMxFile(fileName);
            axMapControl1.ActiveView.Refresh();
            axTOCControl1.SetBuddyControl(axMapControl1);
        }

        ILayer pLayer;//打开属性表的时候使用的图层
        private void btnOpenAttr_Click(object sender, EventArgs e)
        {
            //打开属性表            
            frmAttr frm = new frmAttr(pLayer as IFeatureLayer);
            frm.Show();

        }        
        private void axTOCControl1_OnMouseDown(object sender, ESRI.ArcGIS.Controls.ITOCControlEvents_OnMouseDownEvent e)
        {

            axTOCControl1.HitTest(e.x, e.y, ref item, ref basicMap, ref pLayer, ref Unk, ref Data);
            if (e.button == 2)
            {
