gridview无法更新,已经开了3贴了

Question

代码如下
 protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        OracleConnection conn = new OracleConnection("Data Source=xx;User ID=xx;Password=xx;");
        string strSQL = "update UNIT set UNIT_ID='"
            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[0].Controls[0])).Text.ToString().Trim() + "',UNITID='"
            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',UNAME='"
            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "',UCHIEF='"
            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + "',POST='"
            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[4].Controls[0])).Text.ToString().Trim() + "',PHONE='"
            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[5].Controls[0])).Text.ToString().Trim() + "' where UNIT_ID='"
            + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
        OracleCommand cmd = new OracleCommand(strSQL, conn);
        conn.Open();
        cmd.ExecuteNonQuery();
        conn.Close();
        GridView1.EditIndex = -1;
        GV1();
    }
if (!IsPostBack)处已经重新绑定了,现在的问题是string strSQL = "update 断点跟踪发现取到的值不是更新后的值

UNIT_ID在数据库什么类型的GridView1是否设置了DataKeyNames属性
