 PictureBox temp = new PictureBox();
            temp.Location = new System.Drawing.Point(100, 90 + (20 * NumberOfButton));
            temp.Name = "btn" + NumberOfButton;
            temp.Size = new System.Drawing.Size(((8 * tempWidth) / 100), ((10 * tempHeight) / 100));
            temp.Text = ButtonText;
            temp.Tag = ButtonText;            
            temp.Click += new EventHandler(OnButtonClick);
            String sql = "select Button_id, Button_logo from Button_mst where Button_id=" + NumberOfButton + "";
            DataTable dtLogo = new DataTable();
            _connector.FillTable(ref dtLogo, sql);
            byte[] data = (byte[])dtLogo.Rows[0][1];
            MemoryStream strm = new MemoryStream();
            strm.Write(data, 0, data.Length);
            strm.Position = 0;
            System.Drawing.Image img = System.Drawing.Image.FromStream(strm);
            temp.Image = img;

Are you sure it isn't the size of the picturebox being larger than the image? It should default to a white background.

Try changing backcolor of the picturebox to transparent
Tiwari A K at 26-Apr-12 20:27pm
picture box back color is already transparent

Are you sure that your image has a transparent background? Save the contents of your memory stream to a file and open that with some programs for viewing images - is it really transparent?!
