使用GridView直接編輯更新數據時，出現一個讓我迷惑的問題： GridView編輯更新后綁定的數據仍是未更新前的數據，而再次點擊編輯時才顯示更新后的數據，但當后臺數據是Oracle時，卻不會發生這種情況，這是為什么？ protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e){　　conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + base.Request.PhysicalApplicationPath + ConfigurationManager.AppSettings["AccessFile"]); 　　string sqlstr = "update ComputerList set Machine_ID='"??????????????? + ((TextBox)GridView1.Rows[GridView1.EditIndex].Cells[1].Controls[0]).Text + "' where Computer_Name='"??????????????? + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'"; 　　conn.Open(); ? 　　cmd = new OleDbCommand(sqlstr, conn);　　cmd.ExecuteNonQuery();　　GridView1.EditIndex = -1;　　bind(Session["GetDataSQL"].ToString());} ? public void bind(string GetDataSQL){　　string connStr = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + base.Request.PhysicalApplicationPath + ConfigurationManager.AppSettings["AccessFile"];　　conn = new OleDbConnection(connStr);　　conn.Open();　　ds = this.StoneFunction.GetDSFromAccess(GetDataSQL, conn); 　　DataView view = ds.Tables[0].DefaultView;　　GridView1.DataSource = view;　　GridView1.DataKeyNames = new string[] { "Computer_Name" };　　GridView1.DataBind();　　conn.Close();} ? public override void VerifyRenderingInServerForm(Control control){}
