推荐答案
您可以调用dataGridView1.Rows.Add（）在DataGrid中添加行的函数。
通过 Prasad_Kulkarni ：在DataGridView中添加行（带有预定义列） [ ^ ]。
并检查一个类似的线程 here [ ^ ]。
希望它有所帮助！
- Amit
You can calldataGridView1.Rows.Add()function to add a row in DataGrid.
See a similar solution by Prasad_Kulkarni : Add Row in DataGridView ( with Predefined Columns)[^].
And also check a similar thread here[^].
Hope it helps!
--Amit
datagridview1.Rows.add（）;
这将有助于在datagridview中添加新的datarow
datagridview1.Rows.add();
This will help to add new datarow in datagridview
试试这个
Try this
DataTable ds = (DataTable)dataGridView1.DataSource;
DataRow dr = ds.NewRow();
//index is selected row's index
ds.Rows.InsertAt(dr, index + 1);
dataGridView1.DataSource = ds;
