Get ListRecord ID on click of gallery item

Steve Webb

Solved

Question

I've got a gallery item with list records, which I'm able to populate how I want to. OnClick of an items I need to be able to grab the Id of that record & update a table. I'm fine with the updating, just coming stuck at getting the Id of the record that I'v clicked. Structure below. ThemeRecords is the name of my ListRecord.

On Click event of my container

In debugger the input variable In1 always has a blank value (appreciate it's currently set to Theme_Hdr rather than Id, it's just so as I can return something I recognise, rather than an integer....)

Any idea where I'm going wrong?

So you have the GetOPThemes aggregate, you have it bound to the ThemeRecords Record List.

The container with the OnClick must be an Item of the Record List, and not the full Record List.

Populate the In1 input ThemeRecords.List.Current.OPTheme.Id, it should be in the Widgets expandable section.

Make sure that GetOPThemes is actually returning Ids.

Sample OML attached for my current set up.

This a "bug" in the debugger I believe because of the way outsystems optimises screen and screen action variables. It is working, we just can't see it!

I've attached a working OML

Try it:

- create a Screen variable and an input on the webscreen that show it's value

- in the OnClick action assign ListRecords.List.Current.StaticTable.Id (no need for input parameters) to the new variable

- in the OnClick action refresh the input that shows the new variable

You will see the Id you want is there

Hope it helps!

Hi Steve,

Are you using any client action or destination method after clicking on the container? and which type of application you are using?

It's a traditional web app. After on click it's just a screen action, & I've got a breakpoint in to view the values of local variables.

@Filipe Silva - How do i check the container an item of the record list?
