Answer 1

This is an option:

ThreadPool.QueueUserWorkItem(bcl =>
{
    var bcList = (List)bcl;
    IAsyncResult iftAR = this.dataGridView1.BeginInvoke((MethodInvoker)delegate
    {
        int x = this.dataGridView1.Rows[0].Cells.Count - 1;
        for (int i = 0; i < this.dataGridView1.Rows.Count - 1; i++)
        {
            try
            {
                string imgPath = bcList[i].GifPath;
                Image bmpImage = Image.FromFile(imgPath);
                this.dataGridView1.Rows[i].Cells[x].Value =bmpImage;
            }
            catch (Exception)
            {
                continue;
            }
        }
    }); 
    while (!iftAR.IsCompleted) { /* wait this*/  }
}, barcodeList);
