我是MM该多好呀。你一定是用toolbar中的button来保存的，若用一般的button则没有这个问题，
对这个问题，我的简单做法是，在button的事件里加一行把焦点移到其他地方的语句，如一个文本框等。

在DataGrid快速添加新行
ASP.NET DataGrid为我们提供的内建的记录行编辑功能，但是没有提供内建的添加新行的功能。一个办法就是：在DataTable中添加新行，然后再重新绑定到DataGrid，这个办法可行，但在更新前需要进行确认，可能会产生空行。另外一个解决办法就是：利用DataGrid footer template来提供一个空的行，这样既可以提高速度，也可以避免其它方法带来的不足。为了为浏览者提供一个空行，我们使用DataGrid的Footer Template，我们直接在Footer Template里添加文本框，这样可以避免不必要的操作：比如点击“编辑”按钮等。这样也可以减少往复数据提交的次数。我们这里仍然LinkButton（插入），并设置CommandName属性为“Insert”，这个CommandName在DataGrid的ItemCommand事件中，确保只有用户点击了“Insert”LinkButton才添加记录。添加到数据库的方法是很简单的。下面的这个例子提供了DataGrid快速添加新行的功能。aspx代码和Cohe Behind代码分别如下，注意更改数据录连接字符串：查看例子InsertableDataGrid.aspx<%@ Page Language="vb" AutoEventWireup="false" Codebehind="InsertableDataGrid.aspx.vb" Inherits="aspxWeb.InserTableDataGrid"%>

结束dataGrid的编辑状态
private void EndEdit()
  {
   if (this.dataGrid1.TableStyles.Count != 0)
   {
    this.dataGrid1.EndEdit(this.dataGrid1.TableStyles[0].GridColumnStyles[this.dataGrid1.CurrentCell.ColumnNumber],
     this.dataGrid1.CurrentCell.RowNumber,false);

    this.BindingContext[this.dataView1].EndCurrentEdit();
   }
  }
离开前,可以先设置当前datagrid的CurrentCell
myGrid.CurrentCell = New DataGridCell(1,1)
然后再保存!这种方法虽然糟了一点,但是实用.
先定义一个CurrencyManager绑定到你的DataGrid；
private CurrencyManager DgCm = (CurrencyManager)BindingContext[dataGrid1.DataSource,dataGrid1.DataMember];
当你保存的时候调用下面的两个方法；
this.DgCm.Refresh();
this.DgCm.EndCurrentEdit();
一定成功，我都是这样实现的。
