Navigate to current screen (or refresh entire screen)

Is there a way of either navigating to the the screen you're currently on or at least triggering the OnVisible() function again? I say this because Navigate( SomeScreen), where "SomeScreen" is the currently active screen does nothing.

The use case is that we have a complex screen which uses data from multiple data sources (so obviously we don't use the simple Form control). We perform complicated de-serialisation in the OnVisible() function to get the data from SQL into a form which PowerApps controls can consume.

There's a global "current record" variable which has many foreign keys attached which drive the behaviour of the various groups of screen controls according to a bunch of business rules. This all works very efficiently at the moment.

To add functionality to a new button on this screen which would allow the user to jump to another master record, we set the global record primary key and then tried to Navigate() to ourselves, so that all the code in OnVisible() can run again.

It would be ridiculous to replicate all the OnVisible() code in the button's OnSelect() function. Surely there's a cleaner way?

Being able to add custom behaviour functions to screens (as we can with components) would solve this.

Without knowing your app as well as you do, here's a crude solution: hide a timer on the screen that autostarts and repeats, and move your OnVisible code to the OnTimerStart or OnTimerEnd property. Set the duration for your desired refresh rate, giving your data connections enough time to work.

Hi @MarrinerDev ,

Solution provided by @BCLS776 may cause slow performance issue. If you have lots of actions inside OnVisible, repeat all these actions within a certain duration may increase data loading.

So I would suggest you add a new screen(or in a existing screen, for example, called Screen2) with a Timer control. Then set its:

Duration= 1000

AutoStart=true

OnTimerEnd = Back()

Then on your original screen, add a Navigate button, set its OnSelect=Navigate(Screen2).

This time, each time you click the button to navigate to Screen2, the timer control will work and send you back after one second, and also, actions inside OnVisible will run again.

Best regards,

Allen

To avoid using the timer, just put all of your OnVisible code into an invisible button's OnSelect event. Then, call Select(btnName) in the screen's OnVisilble event, and anywhere else you need to use it.
