Multiple record updation

rameshkumark posted on Wednesday, August 22, 2012

I am newbe to the CSLA.

I need the solution for the following logic.

In my current application I am using Typed Dataset (.xsd)  for performing CRUD implementation.

I have to replace the Typed Dataset from my application and to implement the CSLA.

In my existing application, I have update the database(Multiple Insert, Update and delete) using the typed dataset adapter.Update(DataTable). This will automatically update the multiple records (Insert/Update/Delete) to database in one shot. I need sample for the similar implementation in CSLA.

Search the samples download for UpdateChild and UpdateChildren.

Basically, you will hve

• a list with child objects.
• each child has Child_Insert/Child_Update/Child_Delete methods for update to database (like DataAdapter)
• if "root" list you call the Save method - if child list (owned by another Parent object)  you typically call UpdateCild or UpdateChildren from within the parents DataPortal_XYZ or Child_XYZ methods.

ProjectTracker sample use this technique to update both Project and it's list of Resources within one transaction.
