LS Desktop - Best practice with open screens and refresh RRS feed

  • General discussion

  • Hi,

    My client is confused because saving a screen can impact others and he does not know if/when he has to refresh. Hence he wants to limitate the app to one opened screen at a time which isn't a good idea as the info on one screen can help him take decision on another. I could also refresh all open screens when saving one but i) it slows down the app ii) other screens may have some unchanged data.

    So what do you recommend as a est practice re open screen and refresh? :-)

  • Hi francois.m

    To refresh a screen, it's recommanded to learn the mechanism of communicate across LightSwitch screens, here is an example below:

    • Setup the modal picker on our new order screen to use a screen query instead of the automatic query.
    • Creating an event on our application object that we raise whenever a new customer is added.
    • Handling the event in our new order screen and refreshing the list of customers.

  • Tks for the reply and the link Angie.

    However, it's not so much the mechanism that interests me but what behavior is recommended as a best practice.

    Say you have a stock screem with all your items in store, as well as buy and sell screens. Would you update the stock screen when closing a buy or sell screen? Would you even auto-refresh the stock screen every n minutes because other users may have modified it? Or can there be a mechanism that indicates the user that the screen needs to be refreshed?

    Surely many have faced these questions and could share their opinion :-)
