[导入]关于DATAGRID数据更改时点2次/行号跟不准/失去焦点/丢失e等一系列问题的解决办法：

首先把数据连接/dataadater等信息全放到void bindgrid中，其他地方不用if(!ISPOSTBACK)，在PAGELOAD的时候只用个
   if (!IsPostBack)
   {
       BindGrid();
   }
---------------------------------------------------------------------------------
例如：  private void Page_Load(object sender, System.EventArgs e)
  { if (!IsPostBack)
   {BindGrid();}
  }
  private void DataGrid1_EditCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
  { DataGrid1.EditItemIndex = e.Item.ItemIndex;
   BindGrid();
  }
  private void DataGrid1_CancelCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
  { DataGrid1.EditItemIndex = -1;
   BindGrid();
  }
  void BindGrid()
  { oleDbDataAdapter1.Fill(dataSet11);
   DataGrid1.DataBind();
  }
