Using Object Mapper , Select the field and press Customize,

Check Use Custom Code and Create Descriptor,

Paste the code (Change only cust_firstname to FirstName) below in the custom code section;

I've got the error below.

"An error occurred while refreshing the data from field 'CustomerBase.FirstName' to property 'Text' on control 'TextEdit1.'  Are you missing FieldPropertyDescriptor for a custom property?"

 But this is not custom property. What is missing ?

<Browsable(False), _

BusinessFieldDisplayInEditor(), _

Description("cust_FirstName"), _

DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _

Public Property [FirstName]() As System.String

Get

Return CType(Me.CurrentRow.Item("cust_FirstName"), System.String)

End Get

Set(ByVal value As System.String)

Me.CurrentRow.Item("cust_FirstName") = value

End Set

I've

Public Overrides Function GetValue(ByVal component As Object) As Object

Return CType(component, CustomerBase).cust_FirstName

End Function

Public Overrides Sub SetValue(ByVal component As Object, ByVal Value As Object)

CType(component, CustomerBase).cust_FirstName = CType(Value, System.String)

End Sub

It sounds as though you have answered your own question here.  A property descriptor is created by the BO Mapper for each field.  If you do not want to use the property name assigned by the schema of the table and create a custom property, then either create a separate property or use the custom code option in the BO Mapper.  You can then manually add a ReflectionPropertyDescriptor by overriding the GetCustomBindablePropertyDescriptors method of the BO.  There are many posts related to this:

There is also documentation in this regard.  But if you just go and start changing the generated field name without using the "custom code" option in the mapper, then you are going to have downstream effects like this.

In Custom code section, I've changed property name to a more readable form, Then build partial class. I've also added an override for the GetCustomBindablePropertyDescriptors() function. But I've got known error. This was my process.

I want to use the property (with new name) generated by Mapper. I don't want to define new custom properties for each field. This is the my case.

I've seen that If Only property descriptor was pasted into custom code region, field descriptor class remained the same with old property names after generation.

There must be no need to write anything.

My situation works well. I've have pasted standart property code with changed name into custom code, not selected the option 'Create descriptor' and written code that overrides GetCustomBindablePropertyDescriptors for the property.

Depending on the complications, this may be in the 1.6.5 build....emphasis on "maybe."
