ArgumentOutOfRangeException when toolstripmenuitem click

[nikel]

Hello, I'm trying to pass a variable from main form to child form. The code below is giving me error:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll

Additional information: Index was out of range. Must be non-negative and less than the size of the collection.

list = new List<string>();
 
DataGridViewRow row = programs_dgv.Rows[programs_dgv.CurrentRow.Index];
 
using (InsertData insertData = new InsertData())
{
    list[0] = row.Cells[2].Value.ToString();
    list[1] = row.Cells[3].Value.ToString();
    list[2] = row.Cells[4].Value.ToString();
    list[3] = row.Cells[5].Value.ToString();
    list[4] = row.Cells[6].Value.ToString();
    list[5] = row.Cells[7].Value.ToString();
    list[6] = row.Cells[8].Value.ToString();
    list[7] = row.Cells[9].Value.ToString();
    list[8] = row.Cells[10].Value.ToString();
    list[9] = row.Cells[11].Value.ToString();
    list[10] = row.Cells[12].Value.ToString();
    list[11] = row.Cells[13].Value.ToString();
    list[12] = row.Cells[14].Value.ToString();
 
    insertData._list = list;
 
    insertData.ShowDialog();
    list = insertData.GetValues();
    if (insertData.cancelRequested == true)
    {
        return;
    }
}
