仅返回datagridview的更改的行? [英] Return only the changed rows of a datagridview?

问题描述

我有一个包含datagridview的winform.该表格已与数据完全断开.后面的代码调用一个Web服务，该服务返回一个表.该表成为datagridview的数据源.一旦显示了datagridview，用户就可以编辑他们想要的任何行.当前，当他们单击更新"按钮时，将返回网格中的每一行.

I have a winform that contains a datagridview. The form is totally disconnected from the data. The codebehind calls a webservice, which returns a table. That table becomes the datasource for the datagridview. Once the datagridview is displayed, a user can edit whichever rows they desire. Currently, when they hit the 'Update' button, every row in the grid is returned.

有没有办法只返回datagridview中更改的行?

Is there a way to return only the changed rows in the datagridview?

更新:根据下面的Tezzo的回答，我能够做到这一点:

UPDATE: Based off Tezzo's answer below, I was able to do this:

var changedRows = ((DataTable)dataGridView1.DataSource).GetChanges(DataRowState.Modified).Rows;

推荐答案

您可以使用 GetChanges 在 DataTable 中检索更改.

You can retrieve changes in a DataTable using GetChanges.

因此您可以将此代码与 DataGridView 一起使用:

So you can use this code with a DataGridView:

CType(YourDataGridView.DataSource, DataTable).GetChanges(DataRowState.Modified).Rows
