在C#中的DataSet和之间的DataGridView数据绑定 [英] DataBinding between DataSet and DataGridView in C#
问题描述
我现在有一个窗体上的DataGridView,我想用DataSet中的一个DataTable,从(使用System.Data.SQlite)SQLite数据库填充使用。
I currently have a DataGridView on a form which I want to use with a DataTable in a DataSet, populated from a SQlite database (using System.Data.SQlite).
所以,我有数据库和数据集之间的一个DataAdapter,可以直接设置DataGridView的数据源作为数据表。这显示细腻
So, I have a DataAdapter between the database and DataSet and can set the DataGridView data source directly as the DataTable. This displays fine.
我的问题是这样的:
我为什么要在这里使用绑定源?很多教程说你可以使用与否。但是有什么用呢,不是增加一个额外的步骤等?
My question is this: Why would I want to use a Binding Source here? Many tutorials have said you can use it or not. But is there any use for it, other than adding an extra step?
另外,如果我想在DataGridView的改变要更新的数据库,这怎么可能做了什么?是数据集自动更新 - 所以我只需要告诉DataAdapter的更新吗?或者是那里有一个绑定源是有用的?
Also, if I want the database to be updated when the DataGridView is changed, how can this be done? Is the DataSet automatically updated - so I just need to tell the DataAdapter to update? Or is there where a binding source is useful?
谢谢!
推荐答案
为别人寻找这一点,我发现为什么要使用绑定源的这里。
For anyone else searching for this, I found a good description of why to use a Binding Source here.
同样的这个解释保存/恢复在DataGridView所做的更改。
Similarly, this explains saving/restoring changes made in the DataGridView.
