I thought just binding the PictureBox to the GI_PICTURE column would handle it automatically like a textbox. What I did was what you indicated above:

On the button where the user would click LOAD and selected a file (jpg, etc) after the user selected the file I added:

tbvo_Groupi.GI_PICTURE = new System.Drawing.Bitmap(new System.IO.MemoryStream(ConvertImageToByteArray(pictureBox1.Image, System.Drawing.Imaging.ImageFormat.Jpeg), false));




Added the "ConvertImageToByteArray":

   private byte[] ConvertImageToByteArray(System.Drawing.Image imageToConvert,
                                   System.Drawing.Imaging.ImageFormat formatOfImage)
    {
        byte[] Ret;
        try
        {
            using (MemoryStream ms = new MemoryStream())
            {
                imageToConvert.Save(ms, formatOfImage);
                Ret = ms.ToArray();
            }
        }
        catch (Exception) { throw; }
        return Ret;
    }




This works beautifully.

The set of that property won't get called when you call Save() on the BO.  It will only get called if you set the property to a new value, like this:

On SAVE the SET does not get executed. Not sure why?




        [Browsable(false), BusinessFieldDisplayInEditor(), Description("GIpicture"), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
        public System.Drawing.Bitmap GI_PICTURE
        {
            get
            {
                object value = this.CurrentRow["GI_PICTURE"];
                if (value is byte[])
                {
                    return new System.Drawing.Bitmap(new System.IO.MemoryStream((byte[])value));
                }
                else
                {
                    return new System.Drawing.Bitmap(1, 1);
                }
            }
            set
            {
                System.IO.MemoryStream ms = new System.IO.MemoryStream();
                value.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
                this.CurrentRow["GI_PICTURE"] = ms.ToArray();
            }
        }

If you put a breakpoint there, is ms.Length > 0 after the call to value.Save()?  Does the BO go dirty after the call to this.CurrentRow['field'] = ms.ToArray()?

One last question. On my form where the picture displays, I have a button to load a different picture into the PictureBox and that works. But when I SAVE it doesn't save and I get no error. Keeps the original picture. Here is the code you provided that I used:

 [Browsable(false), BusinessFieldDisplayInEditor(), Description("GIpicture"), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
  public System.Drawing.Bitmap GI_PICTURE
  {
 get
 {
  object value = this.CurrentRow["GI_PICTURE"];
  if(value is byte[])
  {
   return new System.Drawing.Bitmap(new System.IO.MemoryStream((byte[])value));
  }
  else
  {
   return new System.Drawing.Bitmap(1, 1);
  }
 }
 set
 {
  System.IO.MemoryStream ms = new System.IO.MemoryStream();
  value.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
  this.CurrentRow["GI_PICTURE"] = ms.ToArray();
 }
  }

Awesome. Glad it's working for you

YES!!!! Perfect.

How was the data put into the field in the first place?  If the BinaryFormatter cannot deserialize the object, then I'm guessing that it's the raw bitmap data, right?  In that case, you need to change your custom property to the following:

I dragged the MicroFour.StrataFrame.UI.Windows.Forms.PictureBox control on my form and set the column GI_PICTURE as shown below. 


See the error I am getting at the far bottom.







Here is the FieldPropertyDescriptor in the BO:






Here is how the column is set up in the backend SQL Database:



Here is the BO Mapper for the GI_PICTURE column:








Here is the Custom Code for the GI_PICTURE:







Here is more detail of the error that is causing the GI_PICTURE to not display:

absolutely awesome. Worked like a charm.
