Getting this error:

An exception of type 'MicroFour.StrataFrame.Business.BusinessLayerException' occurred in MicroFour StrataFrame Business.dll but was not handled in user code. Additional information: An error occurred while refreshing the data from field 'tbvo_Groupi.GI_PICTURE' to property 'Image' on control 'pictureBox1.'  Are you missing FieldPropertyDescriptor for a custom property?

pictureBox1 is MicroFour.StrataFrame.UI.Windows.Forms.PictureBox

The GI_PICTURE column in a SQL table has the type: varbinary(max).

The BO tbvo_Groupi column GI_PICTURE has a type of System.Byte[]. The Custom Field Properties NULL Value Option is "Don't Allow Nulls". The box for "Use Custom Code" is checked. Here is the custom code:

[Browsable(false), BusinessFieldDisplayInEditor(), Description("GIpicture"), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
        public System.Drawing.Bitmap GI_PICTURE
        {
            get
            {
                object loValue;
                loValue = this.CurrentRow["GI_PICTURE"];
                if (loValue == DBNull.Value)
                {
                    return new System.Drawing.Bitmap(1, 1);
                }
                else
                {
                    try
                    {
                        return (System.Drawing.Bitmap)this.BinaryFormatter.Deserialize(new System.IO.MemoryStream((Byte[])loValue));
                    }
                    catch
                    {
                        return new System.Drawing.Bitmap(1, 1);
                    }
                }
            }
            set
            {
                System.IO.MemoryStream loStream = new System.IO.MemoryStream();
                this.BinaryFormatter.Serialize(loStream, value);
                this.CurrentRow["GI_PICTURE"] = loStream.ToArray();
            }
        }


 

Ah, just remembered that there is a checkbox in the customization dialog in the BOMapper that needs to be checked.  It tells the BOMapper to create the property descriptor for the custom property.  Since you can use the custom code to snuff the property creation, we don't put out a property descriptor by default.
