Hi,

You can delete rows by first selecting the rows and then pressing the Delete key. If you may want to confirm the deletion with the user before deleting them. You can do this with the UserDeletingRow event:

Private Sub DataGridView1_UserDeletingRow( _
       ByVal sender As Object, _
       ByVal e As System.Windows.Forms. _
       DataGridViewRowCancelEventArgs) _
       Handles DataGridView1.UserDeletingRow
        If (Not e.Row.IsNewRow) Then
            Dim response As DialogResult = _
            MessageBox.Show( _
            "Are you sure you want to delete this row?", _
            "Delete row?", _
            MessageBoxButtons.YesNo, _
            MessageBoxIcon.Question, _
            MessageBoxDefaultButton.Button2)
            If (response = DialogResult.No) Then
                e.Cancel = True
            End If
        End If
    End Sub
