Show DataCard when Gallery Item is selected

Posted on by NRFOSTER21

Good day all,

I have a question for the PowerApps visible field. I want the form datacards on my second screen to be visible only when the selected gallery item on Screen 1 relates to that datacard on Screen 2. I want the relationship to be indicated by a “request type” (Ex: Account Service, Network Service, etc.). I cannot seem to get a formula to work. Here is more info:

1. Screen1: contains a Gallery (This gallery’s items populate from a table within the items field)
2. Screen2: contains a Form (Connection: SharePoint List)
3. Request Type: Hardware, Account, Network, Phone, SharePoint, Software
4. Formula Used: If(datacard.text = Gallery.RequestType, True, False)
5. My SharePoint List has over 50 columns (some datacards will only be visible based on another datacard’s value.

What is the best way to achieve this result? Should I set variables for this? Like: If(Argument, true, Set(aVariable))

What do you recommend? Thank you for your time and assistance.

I hope my question is easy to understand, but if you have questions please ask.

You rarely if ever need to use an If() statement with the visible property. If you set up a radio control with the Items:

["Hardware"," Account", "Network", "Phone","SharePoint", "Software"] then set the visible property of each card to

Radio1.Selected.Value="Hardware" or Radio1.Selected.Value="Account", etc depending on which request type you want. If you want some of the cards to be visible for more than one type, you can use something like

Or(Radio1.Selected.Value="Hardware",Radio1.Selected.Value="Software",Radio1.Selected.Value="Network") in any combination you wish as the Visible property of a card. You can substitute a dropdown control for the radio control in the description above. The reason the If() isn't necessary is that the equations above all reduce to either true or false.

Thank you for your timely response! That does make sense for the visibility field, I would essentially be saying the same thing if I just removed the if() statement. Thank you for clarifying that.

Onto the radio/dropdown controls for screen1, I have not planned to use either of that within the gallery itself. To elaborate more on how this gallery has been set up, I have a table that depicts item values, and icons which allow the gallery to take the image of a button which the User can select.

If what I understand is right, you’re saying the scenario, for which is described in your previous response, only allows for a radio or dropdown/choice control. On screen1 for the Gallery Item, would It be possible to then use:
Switch(ThisItem.Selected.Value, “Account”, Set(aVariable, 1), “Network”, Set(aVariable, 2), “Hardware”, Set(aVariable, 3))
Then on Screen2 within a specific DataCard’s visible field use:
aVariable = 1 ?
Unfortunately, I am not able to test this at the moment, so I resulted to inquiring about this on the forum.

Thank you for your time and assistance.

Even simpler,

Gallery1.Selected.'request type'="Account" as the visible property of the card.

No need for Switch or variables. I'm a minimalist!
