Question

I have a data grid on my form filled by a dataset. On the SelectionChanged event I have this code:

int index = dataGridView1.CurrentRow.Index;

But when you click the column to sort the data, a null reference expection gets thrown.

I need to be able to get the current row they have selected and get data out of it. How can I do this?

Answer 1

    void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
    {
        var index = e.RowIndex;
    }
