将特定表格与绘制线相关联？

Question

我正在开发一个GIS应用程序。我想用绘制的线条打开一个特定的表单。将打开的表单包含一个显示行长度的文本框。我可以选择该行。我能够得到线的长度。

我想将表单与每一行链接起来。并且只要选择该行，就应显示相同的表格。我该怎么做？ 我应该去序列化吗？或者有什么好的解决方案吗？

我知道这是与GIS有关的事情，但它更像是一个C＃问题。

代码：

 private bool amDigitizing = false;

    //Coordiant
    private List<DotSpatial.Topology.Coordinate> myDigitizedPoints = new List<DotSpatial.Topology.Coordinate>();
    private List<DotSpatial.Topology.Coordinate> myExtractedPoints = new List<DotSpatial.Topology.Coordinate>();

   // DEM Layer
    private DotSpatial.Controls.MapRasterLayer demLyr;
    // Line Layer
    private DotSpatial.Controls.MapLineLayer LineLyr;
    FormTableEditor ft = new FormTableEditor();



    public Form1()
    {
        InitializeComponent();
        appManager1.LoadExtensions();
        appManager1.CompositionContainer.ComposeParts(toolManager1);
    }



    private void map1_MouseMove(object sender, MouseEventArgs e)
    {
        Coordinate c_mouse = map1.PixelToProj(new System.Drawing.Point(e.X, e.Y));
        Xstrip.Text = "X:" + Convert.ToString(c_mouse.X);
        Ystrip.Text = "Y:" + Convert.ToString(c_mouse.Y);

    }



    private void btnDraw_Click(object sender, EventArgs e)
    {
        try
        {
            //map1.Layers.Remove(LineLyr);

        {

        }

        MessageBox.Show(" Click on the map to draw, double click to stop drawing");
        amDigitizing = true;

        myDigitizedPoints = new List<DotSpatial.Topology.Coordinate>();
        map1.FunctionMode = DotSpatial.Controls.FunctionMode.None;
    }

    private void map1_MouseClick_1(object sender, MouseEventArgs e)

            //double[] s = c.ToArray();

            //StartX = s[0];

        }
