如果你需要删除行的数据，那么就没必要了从数据库中删除它，从gridview中删除它。

If you need the data of deleted row, then no need to delete it from database, remove it from gridview.

private void bindingNavigatorDeleteItem_Click(object sender,
                                                  DataGridViewCellEventArgs e)
{
   int cRow =  gridEventType.Rows[e.RowIndex];   
   gridEventType.Rows.RemoveAt(cRow);
}

试试这个。

Try this.

我使用以下功能解决它。

I have Solve it using the following function.

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
   deletedRowIndex = GridView1.PageIndex * 10 + e.RowIndex; 
}
