Gallery/SubGallery Selecting Item to send to Detail Screen

(0) Share

Report

Posted on by cycle4passion

I have a Sharepoint List DataSource called Census.

I used a guide to create a nested Gallery: https://www.clinkitsolutions.com/academy/creating-gallery-sections-using-subgallery/

I use a Flexible Height Gallery called gallHosp with Items set to:

GroupBy(AddColumns(SortByColumns(Filter(Census, Lower(TextSearchBox.Text) in Lower(OwnerMD) ||Lower(TextSearchBox.Text) in Lower(Lastname) || Lower(TextSearchBox.Text) in Lower(Firstname) || Lower(TextSearchBox.Text) in Lower(ClinicalText)), "Hospital", [Concat(Hospitals, name & ", ")]), "grpHosp", Hospital), "grpHosp", "Items")

I have a nested fixed height Subgallery called gallHosp with Items set to:

ThisItem.Items

Within the subgallery I can reference Data like:

ThisItem.Lastname

Also in this subgallery, I have a right arrow Icon: originally set to:

Select(Parent); Navigate(DetailsScreen)

My DetailsScreen DetailForm1.Items is updated to gallHosp.Selected

But this setup show blank details, so my question is how do I select/reference the item properly so it links appropriately into the DetailsScreen?

@cycle4passion
Try adding this to the OnSelect of the Parent gallery
Set(vRecord, ThisItem)

EDIT: I forgot to mention that in your DetailsScreen set the Form Items property ( I assume you are using a form?) to vRecord.

The LookUp option that @WarrenBelz has set out should also work.

Really though, we are both only guessing at your end needs because we can't see the data you are reshaping. For example, you may need to unravel your GroupBy using UnGroup along with a LookUp to get what you need?

Hi @cycle4passion ,
I cannot test this presently, but if your ID is still in the data group something like
Lookup( Hospital, ID=YourSubGalleryName.Selected.ID )
or going a level higher
Lookup( Hospital, ID=YourMainGalleryName.Selected.Items.ID )
if you have another unique identifier in your data, you could try this instead of ID.

There were some issues with the forum not showing replies for awhile. @WarrenBelz

Main Screen:

Navigate(DetailScreen,ScreenTransition.UnCover, {varHospitalMRN: ThisItem.HospitalMRN})

Detail Screen:

DetailForm1.Item set to LookUp(Census, HospitalMRN = varHospitalMRN)

Hi @cycle4passion ,
I am not a big fan of passing context variables between screens, so try this.
Set(vMRN,ThisItem.HospitalMRN); Navigate(DetailScreen,ScreenTransition.UnCover)
then the Item of the form
LookUp( Census, HospitalMRN = vMRN )
Call the variable whatever you want - I just suggest a different name initially.
