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.
Is there a way to return only the changed rows in the datagridview?
UPDATE: Based off Tezzo's answer below, I was able to do this:
var changedRows = ((DataTable)dataGridView1.DataSource).GetChanges(DataRowState.Modified).Rows;

You can retrieve changes in a
DataTable
usingGetChanges
.So you can use this code with a
DataGridView
