For this week, I’ve continue to develop on the new task which is the pick module. After the UI creation is completed, I’ve inserted some dummy data to test the UI. However, in order to make sure the user always get the latest sales order data from the database for pick module, multithreading is applied to the module.
Multithreading is used in the pick module which aim to refresh the sales order data and update the UI data grid view at the background. Not only that, it also require retrieve the latest row version in order to avoid concurrency error.
However, I’ve faced problem which update data grid binding source in the thread does not reflect in the UI data grid view even thought I’ve define a new collection for the binding source. After I’ve search for solution on the Internet, I’ve learned that I should call dispatcher for UI updating work and for the binding source, I’m only allowed to perform .Clear(), .Add(), AddRange(), and Remove() instead of defining new collection.
