select specific item in a gallery

Hello

 

I have a doubt that, even after some search in the net, seems not to be solvable.

 

I have a (very simple) app in Power Apps, starting from data in a list in SharePoint.

Application is, up to now, only for browsing purposes (no editing / deleting features)

 

I would like to expand details of an item in the list when user click on its title

since list is quite crowded and, eventually, unsorted, what I have done is to:

 

create a gallery (searchGallery) with the list of items (only Title is shown)

create a container where, when user select an item in the gallery, fills few labels with desired details.

create a search feature with a text input (searchInput) where user could enter some text; searchGallery is filtered while user is entering text in searchInput.

create a "reset" button, triggering onSelect will clear searchInput (this will also reset filtered list)

i know which is the ID (and of course all other properties) of the true first item

 

until this point everything is working smoothly

what I am not able to implement a specific behavior while i change something within searchInput, i.e.:

- click resetButton --> remove filter (done), select first visible item (undone)

- insert text in searchInput --> change selected item in gallery while i am writing text

 

something already tried:

set first item as default for gallery --> first item is always selected and i am not able to change selection

add select statement within onselect event of resetButton --> even if filter is removed, selected item is not changed (but first item is correctly selected if i click again on resetButton!)

 

does anybody have something to try?

thanks in advance 🙂

To achieve the desired behaviors in your Power Apps application—specifically, to select the first visible item in a gallery after clicking a reset button or changing the filter through a search input—you can use Power Apps' functions and properties effectively. Here's how you can implement each requirement:

 

Selecting the First Visible Item in Gallery After Reset
To ensure that the first item in your gallery is selected after you clear the search filter, you need to use the Default property of the gallery and potentially adjust your OnSelect action for the reset button. Power Apps does not directly support setting the selected item of a gallery from a function like Select(), but you can manipulate the gallery's Default property and use variables to achieve similar behavior.

 

1. Set a Variable on Reset: Update your reset button’s OnSelect property to clear the search input and set a variable that indicates the first item should be selected. 

 

UpdateContext({varSearchText: ""}); // Clears the search input
UpdateContext({varSelectFirstItem: true}); // Signals to select the first item

 

 

2. Use the Variable to Determine the Gallery’s Default Item: Adjust your gallery's Default property to select the first item based on your variable.

 

If(
    varSelectFirstItem,
    First(SortByColumns(Filter([YourDataSource], StartsWith(Title, varSearchText)), "Title")),
    ThisItem
)

Here, [YourDataSource] should be replaced with your actual data source. This formula checks if varSelectFirstItem is true; if so, it sets the default item to the first item from the filtered and sorted list.

 

3. Reset the Variable After Selection: Ensure you reset varSelectFirstItem to false after the first item has been selected to avoid always selecting the first item automatically. You can do this in the gallery’s OnSelect or any other event that signifies user interaction with the gallery.

 

 

Changing Selected Item in Gallery While Filtering
For changing the selection dynamically as the user types in the search box, you might encounter limitations due to how Power Apps manages gallery selection. The gallery selection is usually driven by user interaction. However, you can influence this by setting the gallery’s Default property dynamically based on the search input, similar to the reset button logic, but more fluid based on the search text.

 

This approach requires careful design to ensure it doesn't interfere with the user's ability to manually select items from the gallery. You may need to consider the user experience thoroughly to ensure that automatically changing the selection does not become frustrating or confusing.

 

Final Note
The key to implementing these features is effectively using variables and the Default property of the gallery. However, due to the user-centric design of Power Apps, automatically changing selections in a gallery can sometimes lead to unintuitive behaviors. Testing with your end-users and adjusting based on feedback will be crucial in finding the right balance between automatic behaviors and manual user control.

I am not sure I understand what you are attempting to accomplish. Are you able to explain the behavior you are looking to achieve? It seems like you need a display form based on my understanding of your topic.

sorry, I have not been very clear.

 

i try with some attached file, starting from a basic app.

app1.png --> on the left a gallery, on the right a couple of text boxes, with test data of selected gallery item.

app2.png --> when text is entered, filter is applied. Here I would like to select first visible item, in this case "bb", as shown in app3.png.

if I click, referring to any of attached pictures, on a "filter reset" button (the lens, in the picture, something more meaningful in the real app) I would like to select first item, "aa", while now selection is not changed.

 

thanks again 🙂

Great!

 

it does work as expected, and it really took very few seconds to implement. I was not sure about correct usage of UpdateContext formula; this implied that setup of default property was wrong.

 

At the end, more than technical explanation, final note was even more important to me.

 

thanks a lot 😊.
