Collect items

[MelvinGRM]

Hi, 

I want to Collect my search-results and automatically transfer them to a new gallery. 

So i triggered my checkbox, if the data match it automatically goes on "check" And if the box is " checked on' it has to collect the item.. Was my idea... But it doesn't work. The checkbox goes automatic if the data match, but wont collect it. It works only if i click on the box / oncheck. Is there a way that it goes automatic, without clicking on a button?

Thanks!

It's hard to tell exactly what's going on there, but it looks like you have a gallery of records, with a checkbox control that is collecting the row into a collection.

What is the source of that gallery? Is the same collection you are collecting into?

What is the default property of your checkbox? Anything in the onchange or onselect property?

Be careful with Boolean controls (toggles, check boxes, etc.) and their respective functions, especially if you're setting the default value. This can trigger functions accidentally, or even create a recursive loop.

Thanks for your message! 

So what i did with my checkbox: 

Default: ThisItem.barcode=TextSearch2.Text (So if it match with my Data it checks on) 

OnCheck: Collect(MyCollection;ThisItem) (I want if it goes OnCheck it goes to my new gallery) 

My second Gallery: 

Items: MyCollection

What's the source of the gallery with the checkbox?

This is an interesting use of behavior based functions, but I would recommend a different pattern. This has the potential to have some performance issues and duplication problems. I can give an example once I know the names of the sources/collections being used.

The first Gallery: 

Search(Tabel1; TextSearch2.Text; "barcode"; "cat")

I would recommend a different pattern, to collect those records.

The main issue with doing it your way, is that (although it will collect automatically), it may collect when you do not want/expect it to.

For example, if you had a barcode value with 00123 and 0012, it would automatically collect the value when you user was typing and paused at 0012. Similarly, if they typed 00124 by mistake and switched it quickly to 00123, you may have collected both.

Instead, I would recommend that you show a button that allows the user to collect the values once they are ready, or use the checkbox to let them click on it to collect that exact record on-demand.

If you want the checkbox to work, the move the function onto the OnSelect property.

If(
    ThisItem in MyCollection,
    Remove(
        MyCollection,
        ThisItem
    ),
    Collect(
        MyCollection,
        ThisItem
    )
)

Then set the Default property for the checkbox to be

ThisItem in MyCollection

This way, you won't ever collect it twice, and the checkbox will set itself automatically to match the presence of the row in the collection.
