Select Gallery Item after Remove

(0) Share

Report

Posted on by KevinBod

Hey all,

I have a gallery with the following code set for the properties,

OnSelect :

UpdateContext({ currentItem: ThisItem });

Default:

currentItem
 
The screen has a form on it whose Item property is set to currentItem.
 
I also have an icon on the screen that will remove the currentItem in the OnSelect handler using this code:
Remove(dataSource,currentItem);
UpdateContext({currentItem:First(qnGallery.AllItems)});
 
 
My problem is that after the calling the Remove method, the Gallery ends up with no selected item, and the form retains the values of the removed item.
 
Can someone see what I am missing and/or how to correct this so the first gallery item will be selected after removing an item?
Thanks
Kevin

What is the datasource of your gallery? I'm assuming it's the same source you're removing the item from but just want to check.

Also, what kind of datasource is it? SharePoint? Dataverse? A custom collection of some sort?

I just tried emulating what you're doing with a Canvas App gallery using sample data from a Dataverse Contacts table, and it seems to work fine.

Hi @KB-07101639-0

This can be tricky with the Default. Instead of using the the Variable, simply make the Default the First of your Items code - example if your Items was
Filter( DataSource, Status.Value = "Current" )

then the Default of the Gallery would be
First( Filter( DataSource, Status.Value = "Current" ) )

You can then simply delete the item and reset the gallery
Remove(DataSource,ThisItem); Reset(Parent)

@Mark Nanneman

Thank you for your response.

Yes, the data source in the remove statement is the same as in the Gallery Items property. It is a SharePoint list.

Thank you for your reply WarrenBelz.

I have made the change as you suggested, and it works great unless I am trying the remove the first item in the gallery. If I try removing the first item, I get the same response as before: the item gets removed from the SharePoint list, but the information in the form does not update (it still shows the item that was removed), and the gallery has no selected item.

FWIW, this is the Gallery Item code (for testing, the search text is empty):

SortByColumns(

Search(

datasource,

qnSearchInput.Text,

'NCR Number','Supplier Name','Supplier Number',Material

),

"ID",

SortOrder.Descending

)

Thank you again for your time.

Kevin

Hi @KB-07101639-0

What I posted is a workaround for something that is a bit unusual and should technically work. I have now created a model based on what I posted and it works fine when the first item is deleted. What I suspect is the Item of the Form is not what it needs to be. Assuming you are using SharePoint, try
LookUp( DataSource, ID = GalleryName.Selected.ID )
