Hi everyone,

Is it possible to set a variable in another canvas app using the Launch function? I would like the user to select a button that will open up another canvas app with a popup already triggered. The popup is triggered by setting a variable to "true".

If this is not possible using the Launch function, any suggestions on how to do this?

Thanks!

Hi @karimabdelrazek ,

Maybe you could try to create a new Screen and add a Timer Control to it, then select the Timer Control and apply the formula provided by @EdViegas .

Hi @EdViegas . Thank you for your reply. I am not able to add any "Navigate" commands to the OnStart property of the app. If I'm not mistaken, adding Navigate commands is no longer supported in the OnStart. Any ideas on how to overcome this?

You need to implement Param function in the launched app. The process is quite simple. First you need to add a condition in the App OnStart property
If( Param("myvar") = "popup", Navigate( Screen1, ScreenTransition.Cover, { VarPopUp: true } ) )
Then, append param name and value to app's url like
Launch("https://your_app_url?myvar=popup", {}, "New")
