Select Gallery Item to view Ticket Details

[Daemagor]

When I select a ticket, which is associated with a gallery called TicketsGallery. The OneSelect event goes to the new screen that views the ticket details.

 

In the Editor, I am able to see the TicketsGallery.Selected.________. When I run the app itself, the ticket's details dont show and this is due to the error in the picture. What am I doing wrong?

This is what it looks like when you are in the editorThis is what it looks like when you run the App

Anyone have an idea why this isnt working?

It is quite hard to understand what problem you are having maybe more screenshots would help to troubleshoot.

This is what I understood.

You have 2 screens 

Screen 1 has gallery which shows Tickets.

You have an OnSelect which navigates to Screen 2 to show details for selected ticket. Now is this OnSelect inside the Gallery? Because if it is not then TicketsGallery.Selected would not have a value.

On your second screen (Ticket details screen) how are you displaying the info? Are you using Form to do it? In second screen if you add label anywhere and write TicketsGallery.Selected.ID (Or any other column) does it display?

"You have an OnSelect which navigates to Screen 2 to show details for selected ticket. Now is this OnSelect inside the Gallery? Because if it is not then TicketsGallery.Selected would not have a value."This is the On select for the gallery on screen 1

"On your second screen (Ticket details screen) how are you displaying the info? Are you using Form to do it? In second screen if you add label anywhere and write TicketsGallery.Selected.ID (Or any other column) does it display?"

I am displaying the info in a form called TIcket_Details with the datasource correct. In the Item, I have Display_tickets.selected and it will display that error. But when I make a label and have Display_tickets.selected.id works

Hi Daemagor,

I assume that this documentation about PowerApps Forms could be a reference for you, you could check the part “Build an app from scratch” for more details:
https://powerapps.microsoft.com/en-us/tutorials/working-with-forms/

According to your description, I would suggest you use the Navigate function without transferring value from the gallery screen to the detail screen. Just simply navigate from the gallery screen to detail screen.

On your second screen, please set the Display form’s Item property as Gallery1.Selected.

Then when you select an item on the Gallery and navigate to the detail screen, the details of the selected item will be shown on the detail screen.

Please try it on your side and feel free reply if you need more help.

Best regards,
Mabel Mao

@v-yamao-msft,

That does not work. This is exactly what I have and it's giving me the error I has posted above. I have also stored the selected value into a variable, passed it to the other view and that still doesnt work.

1. Screen1: Gallery has navigate to Screen2 and sends over stored selected value for more testing
2. Screen2: Form has the correct datasource and the item is Gallery1.Selected

This does not work.

But like I have said, if I use a label and not a form, Gallery.Selected.____ works.

I have no idea why this isnt working, it should be working...

Just to clarify, when you say that you are navigating to another page through an OnSelect, do you mean for instance you have an icon or label that is clickable in each row of the gallery that is taking you there? Like how by default the gallery has arrows after each entry?

@Anonymous,

I have an icon in the gallery that has the navigating OnSelect value. 

Though, I have fixed the problem. What I needed to do was to create a new Gallery and delete my old one for it to work..... Thanks for everyone that commented on this post!
