How can I clear Gallery.Selected/ThisItem

I have a Gallery which's Selected-property I would like to define by my code (a context variable or something like that). But on Gallery.Selected you cannot use = or any other operator. What would a solution be?

 

Thanks in advance.

Hi

 

Can you provide details or examples so that this can be easily figured out to support you as much as possible?

Thanks

Let's say you have a Gallery like in the Service Desk Example (Currently I cannot make an app from template, might be a temporary issue, hence the question here and not testing myself in existing code 😉 ).

I have filter buttons which create filters to the data source. If e.g. switch the filter I want that the Gallery selects the first element. On click of these elements I set the a context variable (currec: ThisItem). It works to show the data in a form or so with this context variable but e.g. Gallery.Selected = currec does not work, because there doesn't seem to be an overload for the operator= for this property. So my question would be how I can clear or set the Gallery.Selected so the Gallery "jumps" to what ever element I specified.

Hi, if I understand your needs correctly then in theory the Default property of the gallery is what you would need to use.

 

However:

1) Setting this property to either First(MySource) or First(Gallery1.AllItems) has not actually changed the behaviour of my test gallery

2) There seems to be no corresponding Reset property such as exists for text input controls that also have the Default property

 

It would be great if someone who knows could clarify how to use the Default property of galleries.

 

On a different tack, are you really sure you need to have one of the items of the gallery selected by default?  What is the scenario whereby you need to "jump" to another element without it actually being selected in the gallery by the user?

Hi

 

Sorry for my poor understanding of your explanation. If you have data and linked here, maybe I can understand better. :).

 

Anyway, I try to figure out your question.

Filtering:

In sample or create apps from PowerApps, Gallery is always linked to datasource (say TableX). Then, in your filtering, you always see that they set Items = Filter(TableX, TextInput1.Text in ColumnTitle).

This is more on PULLING method.

 

I would suggest that using PUSHING method.

Set the Items of the Gallery to any name, say : SourceX

Then add any Button, or Image, Box, TextInput and set

OnSelect / OnChange =  ClearCollect(SourceX, Filter(TableX, TextInput1.Text in ColumnTitle1 || TextInput1.Text in ColumnTitle2 ||.....)) or if using

Search: Set as : Search(TableX, TextInput1.Text, "ColumnTitle1", "ColumnTitle2", "ColumnTitle3",..)

 

I wish I am replying to the right things.

If not, please link the app / excel and I will try to rewrite.

 

Hope this helps.

Hi

 

If I did not misunderstand you, then the following may be able to explain better:

(I am using Project Siena for quick demo and it is the same for PowerApps).

I had a similar need for my app. In the end, I decided not to bind my elements to Gallery.Selected despite how convenient it was.

I used a context variable instead, since it is currently more flexible: 

  1. Add a Button within the gallery. Stretch it across the template. Remove its text.
  2. Set the Button's Fill to: 
    RGBA(0, 0, 0, 0)
  3. Set Button.OnSelect to:
    UpdateContext({variable: put Gallery.Selected.ThisItem, true/false, or whatever value/text you need here})
  4. Apply the variable to your needs. You can use variable just like ThisItem.
    variable.YourColumnHere
  5. I don't have a fix for clearing the Gallery.Selected. Instead, I made the Visible property of my other item to be FALSE whenever my variable was blank or empty:
    Set another Button to clear the variable:
    
    UpdateContext({variable: ""})
    
    Or if the variable was a table:
    
    UpdateContext({variable: Defaults(the table referenced in the Gallery)})
    
    Then set the Visible property of your other items affected by Gallery.Selected to:
    
    !IsBlank(variable)     <----- if your variable is some kind of text/value
    !IsEmpty(variable)     <----- if your variable is a table

Can you try setting Gallery.Default = currec? That should work.

Sorry guys, I am currently not working on this project, but I will come back to you when this topic is an issue again. Thanks though for your proposals, I will test them soon

Thank you, @mr-dang. I had a similar issue and this fixed it.
