I had add a new property to Customer and new column in dbo.Customer. I can write data to the new column during registration. But when I want to see list of all customers I get a grid with empty column of my new property. I found out that methode GetAllCustomers in CustomerService contains code:
var query = _customerRepository.Table;
Of course there is no my new column in this query.....
It sounds like you already added your new property to the Customer entity so I'd guess you need to add it to the admin Customer view model and then update the PrepareCustomerModelForList method in the CustomerController to populate your property.
My new property in Customer Entity is ClientNumber. The column ClientNumber in dbo.Customer is not empty. I have add to the script in List.cshtml after <div id="customers-grid"></div>:
