how to show collection data in Gallery.

[dinesh12]

Scenario :- I have created a flow where trigger is PowerApps. It takes the data from API and using PARSE JSON then sharing the response back to the PowerApps. There all the responses are stored in Collection. Now i want to display that data in Gallery. Please check the below images. 

In powerapps please see the formula i have written. 

In another screen i have added the Gallery connected the data source to collection. Data is getting saved properly in collection. 

But i want to show the articles data in Gallery i can able to get the status and totalres values in Gallery. 

When i try to use this formula in gallery it is getting error message as :- 

I want to show the data exists inside the articles. Is there any way to achieve that ???

Once you use article on the Items of the Gallery,

Use:

ThisItem.Title.Value

Hi @dinesh12 :

Do you want to display the data in the "article" in the gallery?

Is there only one record or multiple records in artilce?

The key is to use sub gallery.I've made a test for your reference:

My datasource:

ClearCollect(test,{status:"ok",totalRes:"10",articles:Table({colmun1:"1",column2:2})})

1\Add a gallery 

Items:

test

2\Add a gallery into the first gallery

Items:

ThisItem.articles

@v-bofeng-msft That's awesome Thanks a lot for your help. it's really working fine. If you can help me in just one more scenario then it would be really helpful. 

I have followed your steps adding gallery inside gallery that works. But if we click on Arrow then it will go the next screen. In that Screen I want to display the description field. If user clicks on any one of the item in the Gallery then related description should appear in Next Screen. Description data is stored in Collections itself. 

I have tried adding the label in the next screen. Tried the below formula.

Gallery13.Selected.Description it is now showing any data there.

Also i have tried adding the gallery inside the gallery and adding the label again in that. If i do that i am getting the description but all items descriptions in one screen. But i don't want that. If user clicks on any item then related description should appear in next screen.

You can create a variable on the arrow or Icon OnSelect of the Gallery. So on the icon inside the Gallery put;

Set(MySelected,ThisItem.Description)

Then in the Text of the Label put;

MySelected

Hi @dinesh12 :

Could you tell me:

• Is Gallery13 a sub- gallery?

If yes, then I suggest you try @eka24 's suggestion:

Add a button to store the result in a variable and call the variable.
