COMPONENTS: Set Gallery Default based on screen?

[seadude]

Hello,

I have a menu component that I like to drop into new apps. The menu consists of a Gallery of screen names. When user clicks on a screen name, they navigate to that particular screen. No problems here.

Issue:

• The Gallery Default property is set to `{}` (blank)
• I need it set to the current Screen

I can't quite figure out how to access a sreen control name through a Component.
Any ideas?

Hi @seadude 

I carried out a test on my side and you can use below expression on the "Default" property of your Gallery control:

Expression: {Value: App.ActiveScreen.Name}

Hope this Helps!

Hi @yashag2255 , Thank you very much for the assistance! The menu must be clicked two times to "stick". Can you tell why?

Scenario:

• Component Custom Property (cmpMenuItems) placeholder code:

  Table({screen:"Test", screenName: "SampleText", icon: SampleImage})

• Component Gallery Items property:

  componentName.cmpMenuItems

• Component Gallery Defualt property:

  {screen: App.ActiveScreen.Name} // Requires clicking twice 

• Component Gallery OnSelect property:

  Navigate(
      LookUp(colMenuItems,
          ThisItem.screenName = screenName, screen
      )
  )

• App OnStart code:

  ClearCollect(
          colMenuItems,
          {screen: scrHome, screenName: "Home", icon: Icon.Home },
          {screen: scrReports, screenName: "Reports", icon: Icon.Document},
          {screen: scrMaps, screenName: "Maps", icon: Icon.Pin},
          {screen: scrContacts,screenName: "Contacts", icon: Icon.Person}
  )

• Component (in app) cmpMenuItems property: colMenuItems

Are you able to tell why the menu must be clicked twice to "stick"?

Hi @seadude 

Can you try to modify few properties as:

Component Custom Property (cmpMenuItems) placeholder code:

Table({screen: App.ActiveScreen, screenName: "Home", icon: Icon.Home })

Component Gallery Default property:

LookUp(Component1.CustomProperty1,screen = App.ActiveScreen)

Component Gallery Icon OnSelect property:

Navigate(LookUp(Component1.CustomProperty1,screenName = ThisItem.screenName).screen)

I carried out a test on my side and using below properties the component was working fine. There was no need for selecting the icon twice.

Hope this Helps!

Hi @yashag2255 ,

Thank you VERY much for the assistance. You taught me a few very insightful things! And your solution worked. There is still some strange behaviour (a double-clicking- type thing happening, but its not a showstopper).

Thanks again!
