DataGridViewRowCancelEventArgs e)
{
DataGridViewRow startingBalanceRow = DataGridView1.Rows[0];
// Check if the Starting Balance row is included in the selected rows
if (DataGridView1.SelectedRows.Contains(startingBalanceRow))
{
// Do not allow the user to delete the Starting Balance row.
MessageBox.Show("Cannot delete Starting Balance row!");
// Cancel the deletion if the Starting Balance row is included.
e.Cancel = true;
}
}
Private Sub UserDeletingRow(ByVal sender As Object, _
ByVal e As DataGridViewRowCancelEventArgs) _
Handles DataGridView1.UserDeletingRow
Dim startingBalanceRow As DataGridViewRow = DataGridView1.Rows(0)
' Check if the starting balance row is included in the selected rows
If DataGridView1.SelectedRows.Contains(startingBalanceRow) Then
' Do not allow the user to delete the Starting Balance row.
MessageBox.Show("Cannot delete Starting Balance row!")
' Cancel the deletion if the Starting Balance row is included.
e.Cancel = True
End If
End Sub
