How to insert data from list to a column of data grid view

I have a data grid view (dataGridViewPorosity) with 2 columns and I want to insert data from a list (Porosity) to one of this columns, but the exception is: Index was out of range. most be non-negative and less than the size of the collection.

here is my code:

        var source = new BindingSource
        {
        DataSource = Porosity
        };
        for (int i = 0; i < source.Count; i++)
        {
             dataGridViewPorosity[1,i].Value = source[i];
        }

I saw the similar questions but cannot fix the problem

The DataGridView control works differently from the other tables you might know (or arrays). You need to choose the row and cell. The cell is basically the column.

dataGridViewPorosity.Rows[rowNumber].Cells[cellNumber].Value = source[i];

I assume you want to use the second cell and the row with the i value. You can do it just like that:

dataGridViewPorosity.Rows[i].Cells[1].Value = source[i];

Good luck!

EDIT: Try to create new rows, like so:

int rownum = dataGridViewPorosity.Rows.Add();

And then use the rownum as the row number you would like to insert your data to.

dataGridViewPorosity.Rows[rownum].Cells[1].Value = source[i];

Of course, these must be in the for loop.
