如何在datagridview中增加行、列？？

Question

如题，在已有的datagridview中新增行、列，后填充数据。如何实现？？

Answer 1

指定资料来源后呼叫DATABINDING方法不就好了吗？

Answer 2

现在需要的是，自己填充指定数据。不通过数据源（datasource）
即象使用table（Web）或stringgrid（delphi）一样。

使用未绑定的 DataGridView 控件
using System;
using System.Drawing;
using System.Windows.Forms;public class Form1 : System.Windows.Forms.Form

    private Button deleteRowButton = new Button();    public Form1()
    {
        this.Load += new EventHandler(Form1_Load);
    }    private void Form1_Load(System.Object sender, System.EventArgs e)
    {
        SetupLayout();
        SetupDataGridView();
        PopulateDataGridView();
    }    private void songsDataGridView_CellFormatting(object sender,

Answer 4

上面这段代码是直接从.net framework2.0帮助中复制过来的，对lz来说，最有用的代码其实就几句而已：
string[] row0 = { "11/22/1968", "29", "Revolution 9", "Beatles", "The Beatles [White Album]" };
songsDataGridView.Rows.Add(row0);

Answer 5

但是如果想像使用table（Web）或stringgrid（delphi）一样“堆积木”般地灵活控制它，这恐怕不行
