Is it possible to have a Read-Only Root Collection with Read-Only Child Collection?
I want to provide a UI search facility where the user can search for account names using wild cards (i.e. those with 'Santos' as Last Name).
The UI will show a DataRepeater with the matching Customer Names (Read-Only Root Collection). Each Customer Name will have their own DataGridView showing the Purchases (Read-Only Child Collection) of the respective customer.
If this is possible, can you please help me with a simple example? Thank you.
I don't understand why you want this object to be a root object, why cannot this just be a standard ROL?
If saving is important, then what would be wrong with a BLB with a BB that contains only read-only properties?
Can the user ever save the collection, based on what I interpret it appears to be only for viewing. You could either have a factory that passes in the search criteria or if you have already fetched the objects could be filtered using either LINQ / FilteredBindingList depending on your preference in the UI.
Please correct me if I am missing something?
Yes, I want a Read-Only List/Collection, so saving is unnecessary.
I want to display a list of Read-Only Parent List, each with a Read-Only Child List. In a DataRepeater control, the parent will be displayed in textboxes, while the children will be displayed in a datagridview.
Please help me with some samples. Thank you.
Is this what you want?
public sealed class CustomerList : ReadOnlyListBase<CustomerList, CustomerInfo> { public static CustomerList GetCustomers(object criteria ); }
public sealed class CustomerInfo : ReadOnlyBase<CustomerInfo> { internal static CustomerInfo GetCustomer(object custData); }
public sealed class PurchasesList : ReadOnlyListBase<PurchasesList, PurchaseInfo> { }
public sealed class PurchaseInfo : ReadOnlyBase<PurchaseInfo> { }
Andy,
yes, i want the business objects.
i want to implement the customerlist as the parent list, with each of the customer having a child collection of purchases list.
can you please help me some samples?
thank you.
