How to prevent deleting empty row in dataGridView?

Question

C++ / C#

Good afternoon, please help, the problem is that when I delete an empty row in the datagrid, I get an error in
dataGridView1.Rows.RemoveAt (e.RowIndex)
As I understand it, you need to check the row, if it is full, then deletion is possible if it is empty, then no.

Please tell me how to implement it...

Answer 1

Decided so

var senderGrid = (DataGridView)sender;
            if (e.RowIndex == dataGridView1.NewRowIndex || e.RowIndex < 0)
                return;

            if (e.ColumnIndex == dataGridView1.Columns["DeleteButtonColumn"].Index)
            {
                dataGridView1.Rows.RemoveAt(e.RowIndex);
            }

Answer 2

1. Either set AllowUserToDeleteRows = false
2. Or check the index before deleting a row
