Anyone here good with dataGridViews? Everytime i save the data in adds an empty row and since im saving everytime Form1_FormClosing is called it looks like this:

which is very annoying

The code I use to save is:

string file = Dir + "filename.bin";
using (BinaryWriter bw = new BinaryWriter(File.Open(file, FileMode.Create)))
{
    bw.Write(dataGridView2.Columns.Count);
    bw.Write(dataGridView2.Rows.Count);
    foreach (DataGridViewRow dgvR in dataGridView2.Rows)
    {
        for (int j = 0; j < dataGridView2.Columns.Count; ++j)
        {
            object val = dgvR.Cells[j].Value;
            if (val == null)
            {
                bw.Write(false);
                bw.Write(false);
            }
            else
            {
                bw.Write(true);
                bw.Write(val.ToString());
            }
        }
    }
}

Disable AllowUserToAddRows. I think you're writing the default empty row to the file as well as the data you've added yourself. That's what it looks like from the information you've given anyways. If it doesn't work, then feel free to add me on Steam.	bunnyslippers69 Offline Diamond Boarder Posts: 3539 Thanks received: 1185 Karma: 0
