第一步：新建另外一个窗体

• 首先要定义一个全局变量 ILayer。
• 窗体要带参数，以便将 ILayer 传递过来。
• 获取属性列表。

  using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using ESRI.ArcGIS.Carto;using ESRI.ArcGIS.Geodatabase;namespace MyGIS{    public partial class Property : Form    {        ILayer pLayer;        public Property(ILayer layer)        {            InitializeComponent();            pLayer = layer;        }        private void Property_Load(object sender, EventArgs e)        {            IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;            IFeatureClass pFeatureClass = pFeatureLayer.FeatureClass;            IFeatureCursor pFeatureCursor = pFeatureClass.Search(null, false);            IFeature pFeature = pFeatureCursor.NextFeature();            IFields pFields = pFeatureClass.Fields;            DataTable pDataTable = new DataTable();            for (int i = 0; i < pFields.FieldCount; i++)//获取所有列            {                DataColumn pColumn = new DataColumn(pFields.get_Field(i).Name);                pDataTable.Columns.Add(pColumn);            }            while (pFeature != null)            {                DataRow pRow = pDataTable.NewRow();                for (int i = 0; i < pFields.FieldCount; i++)                {                    pRow[i] = pFeature.get_Value(i);                }                pDataTable.Rows.Add(pRow);                pFeature = pFeatureCursor.NextFeature();            }            dataGridView1.DataSource = pDataTable;        }    }}

  第二步：建立右键菜单项

  • 添加一个 ContextMenuStrip 控件，然后增加几个菜单项。
  • 特别注意加入一个菜单项为“显示属性”。
  • 判断在什么情况下显示右键菜单。

     ILayer pGlobalFeatureLayer; private void axTOCControl1_OnMouseDown(object sender, ESRI.ArcGIS.Controls.ITOCControlEvents_OnMouseDownEvent e)        {            if (e.button == 2)            {                esriTOCControlItem item = esriTOCControlItem.esriTOCControlItemNone;                IBasicMap pBasicMap = null;                ILayer pLayer = null;                object other = null;                object index = null;                axTOCControl1.HitTest(e.x, e.y, ref item, ref pBasicMap, ref pLayer, ref other, ref index);                pGlobalFeatureLayer = pLayer;//实现赋值                if (item == esriTOCControlItem.esriTOCControlItemLayer)//点击是图层的话，就显示右键菜单                {                    contextMenuStrip1.Show(axTOCControl1, new System.Drawing.Point(e.x, e.y));//显示右键菜单，并定义其位置，正好在鼠标处显示                }            }        }        private void 显示属性ToolStripMenuItem_Click(object sender, System.EventArgs e)        {            Property frm = new Property(pGlobalFeatureLayer);            frm.Text = "Attributies of" + pGlobalFeatureLayer.Name;            frm.ShowDialog();        }
