C # DataGridView dynamically adding columns and rows

https://blog.csdn.net/alisa525/article/details/7350471

dataGridView1.ReadOnly = true; // disable editing functions

Method One: Add Datatable manually, and then bind dataGridView

DataTable dt = new DataTable (); // build data tables

dt.Columns.Add (new DataColumn ( "id", typeof (int))); // add a column of type int table

dt.Columns.Add (new DataColumn ( "Name", typeof (string))); // add string type of the Name column in the table

DataRow dr; // row
for (int I = 0; I <. 3; I ++)
{
      DR = dt.NewRow ();
      DR [ "ID"] = I;
      DR [ "the Name"] = "the Name" + I;
      dt.Rows.Add (dr); // add this line of the table's row object
}

dataGridView1.DataSource = dt;

If you want to add a column textbox effect, do the following processing

dt.Columns.Add(new DataColumn("选中", typeof(bool));

Method two: directly inserted in the dataGridView

        dataGridView1.ColumnCount = 4;
        dataGridView1.ColumnHeadersVisible = true;

        // Set the column header style.
        DataGridViewCellStyle columnHeaderStyle = new DataGridViewCellStyle();

        columnHeaderStyle.BackColor = Color.Beige;
        columnHeaderStyle.Font = new Font("Verdana", 10, FontStyle.Bold);
        dataGridView1.ColumnHeadersDefaultCellStyle = columnHeaderStyle;

        // Set the column header names.
        dataGridView1.Columns[0].Name = "Recipe";
        dataGridView1.Columns[1].Name = "Category";
        dataGridView1.Columns[2].Name = "Main Ingredients";
        dataGridView1.Columns[3].Name = "Rating";

        // Populate the rows.
        string[] row1 = new string[] { "Meatloaf", "Main Dish", "ground beef",
            "**" };
        string[] row2 = new string[] { "Key Lime Pie", "Dessert",
            "lime juice, evaporated milk", "****" };
        string[] row3 = new string[] { "Orange-Salsa Pork Chops", "Main Dish",
            "pork chops, salsa, orange juice", "****" };
        string[] row4 = new string[] { "Black Bean and Rice Salad", "Salad",
            "black beans, brown rice", "****" };
        string[] row5 = new string[] { "Chocolate Cheesecake", "Dessert",
            "cream cheese", "***" };
        string[] row6 = new string[] { "Black Bean Dip", "Appetizer",
            "black beans, sour cream", "***" };
        object[] rows = new object[] { row1, row2, row3, row4, row5, row6 };

        foreach (string[] rowArray in rows)
        {
            dataGridView1.Rows.Add(rowArray);
        }

Column inserted DataGridViewCheckBoxColumn

DataGridViewCheckBoxColumn column = new DataGridViewCheckBoxColumn();
{
column.HeaderText = "选中";

column.Name = isSelected;

        column.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
        column.FlatStyle = FlatStyle.Standard;
        column.ThreeState = true;
        column.CellTemplate = new DataGridViewCheckBoxCell();
        column.CellTemplate.Style.BackColor = Color.Beige;
    }
DataGridView1.Columns.Insert(0, column);
