你好, 我有一个使用DataSource连接到DB的网格视图. 数据源具有一个查询,该查询从数据库中选择具有特定ID的项目. 另外,我有一个DropDown-List,我想更新dataSource的查询,因此,当用户从DropDown-List中选择某个索引时,它将在Grid View中显示相关数据. 请帮忙!
Hello, I have a Grid View that connected to DB with DataSource.

Please Help! Thanks.
推荐答案使用BindingSource.Filter过滤您的dataGridView. 更改DropDownList_SelectedIndexChanged中的过滤器. Use BindingSource.Filter to filter your dataGridView. change the filter in DropDownList_SelectedIndexChanged.
