在C#中使用控件DataGridView直接增删改数据库表的内容
能不能不用按钮，在_CellBeginEdit和_CellEndEdit直接实现增删改？求代码，详细最好啊，--------------------编程问答--------------------
--------------------编程问答-------------------- 最后一行没法保存，而且修改好了直接关闭窗体再打开看没效果啊
private SqlDataAdapter sda;
private void Form3_Load(object sender, EventArgs e)
{
string connString = "server=.;database=test;uid=sa;pwd=Cdyouxi.kgen-1";
string selectTxt = "select * from a";
this.dataGridView1.DataSource = GetData(connString, selectTxt);
}
private DataTable GetData(string connString, string selectTxt)
{
SqlConnection conn = new SqlConnection(connString);
SqlCommand cmd = conn.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = selectTxt;
sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);
SqlCommandBuilder scb = new SqlCommandBuilder(sda);
return dt;
}
private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
this.sda.Update((DataTable)this.dataGridView1.DataSource);
}

除
--------------------编程问答--------------------
this.dataGridView1.DataSource = GetData(connString, selectTxt);this.dataGridView1.databind();//少了重新绑定。、 --------------------编程问答--------------------
补充：.NET技术 , C#
