编辑datagridview并将其保存到数据库

问题描述

你好！
我在winform上有一个datagridview，其中从ms Access数据库填充表的记录.我希望datagridview是可编辑的，所以我启用了datagridview的编辑.但是对gridview单元格或行所做的更改未保存在数据库中，因此当我再次运行该应用程序时，它不会在datagridview中显示已编辑的记录.

如何使datagrid视图可编辑，并且在编辑记录后必须将其保存在数据库中.

感谢

Hello!!
I have a datagridview on my winform in which i m populating the records of a table from ms access database. I want the datagridview to be editable , so i enabled editing of datagridview. But the changes made to gridview cell or row are not saved in database, hence when i run the application again it doesn''t shows the edited records in datagridview.

How can i make datagrid view to be editable and after editing records must be saved in database.

Thanks

推荐答案

OleDbCommandBuilder build = new OleDbCommandBuilder(adapter);

用于构建upadate查询并在保存记录按钮上单击事件，请写以下行:

for building the upadate query and on save record button click event write the below line:

adapter.Update(dt);

其中adapter是OleDbDataAdapter的对象，而dt是DataTable的对象

谢谢.

where adapter is a object of OleDbDataAdapter and dt is object of DataTable

Thanks.
