protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
string str = "Data Source=PC;uid=sa;pwd=lenovo;Initial Catalog=liuyanban";
SqlConnection conn = new SqlConnection(str);
conn.Open();
if (e.CommandName.ToString().Equals("add"))
{
string a = GridView1.SelectedRow.Cells[0].Text.ToString();
string b = GridView1.SelectedRow.Cells[1].Text.ToString();
string c = GridView1.SelectedRow.Cells[2].Text.ToString();
string d = GridView1.SelectedRow.Cells[3].Text.ToString();
string insertquery = string.Format("INSERT INTO dbo.display(姓名, 性别,时间,留言)values ('{0}','{1}','{2}','{3}')", a, b, c, d);
SqlCommand cmm = new SqlCommand(insertquery);
cmm.Connection = conn;
{
string str = "Data Source=PC;uid=sa;pwd=lenovo;Initial Catalog=liuyanban";
SqlConnection conn = new SqlConnection(str);
conn.Open();
if (e.CommandName.ToString().Equals("add"))
{
string a = GridView1.SelectedRow.Cells[0].Text.ToString();
string b = GridView1.SelectedRow.Cells[1].Text.ToString();
string c = GridView1.SelectedRow.Cells[2].Text.ToString();
string d = GridView1.SelectedRow.Cells[3].Text.ToString();
string insertquery = string.Format("INSERT INTO dbo.display(姓名, 性别,时间,留言)values ('{0}','{1}','{2}','{3}')", a, b, c, d);
SqlCommand cmm = new SqlCommand(insertquery);
cmm.Connection = conn;
先查找GridView1里的控件，然后添加事件。

中有示例。
居然是c++。。。少见呢。
自问自答？
你没触发事件，执行个鸟啊
有 conn.Open();
没有关闭连接，要我说什么呢
