Will you have an updated video training?

From what I saw in the demo it is very good, but I want to wait for buy it until an update is available.

Thanks Ben -



That did the trick for building ! ( oddly the inherits line was in the ordersBO but not CustomersBO )



When I tried to fill top 100 I did get this unhandled exception

MicroFour.StrataFrame.Business.BusinessLayerException was unhandled by user code

Message="An error occurred while refreshing the data from field 'CustomersBO.cust_lname' to property 'Text' on control 'Textbox5.' Are you missing FieldPropertyDescriptor for a custom property?"

But there is that hint this may have something to do with a FieldPropertyDescriptor so I'll just consider working through that a learning experience



This stuff is fun !



Thanks again

Each property that gets created through the BO Mapper has a class created for it as well which is a FieldPropertyDescriptor class that prevents reflection from being used when binding to a control.  When you use the BO Mapper these are automatically created for you.  It appears that his BO would simply need to have the partial class rebuilt and it will create the field property descriptor class.

The only time that you need to manually create a property descriptor is when creating custom fields that will be bound to controls.  There are some samples on this as well as some info in the docs as to what needs to be done here.  In fact, the tutorial shows how to create the property descriptors for a custom field.

Looking at the name of the field within your BO, the cust_lname in the sample was changed to cust_FirstName some time ago (column name in the database changed).  So, if you're rebuilding your partial class from the fields in the database, it should pick up the correct name, and the textbox is probably still bound to the old name "cust_lname".  Is there any way you could download the latest release?  All of the samples in the latest release have been updated so that they reference the new fields...
