Gallery does not re-sort after changing a date

I have a gallery of items that gets sorted and filtered when the user selects a project from a combo box. Sorting is primarily by date. This works fine. However if I change a date in one of the items using a date picker control, which pushes the updated date into the collection bound to the gallery, sorting does not change initially. If I reselect the date a second time, the gallery then sorts, or if the user reselects something in the combo box above the gallery, it sorts.

is there any code to force the sorting to be immediately after changing a date?

Gallery does not re-sort after changing a date

In response to TimL and WarrenBelz, thanks very much. I attempted TimL's suggestion of resetting the gallery (and it did appear that the DelDateSort column in the collection was being immediately updated), but this did not work.

So I ended up adding a Select statement at the end of the OnChange code in the date picker control to Select the Project combo box at the top of the page. This essentially re-runs the code that gets data, filters and sorts the items for the gallery. I was trying to avoid that, thinking it would be slow or use un-necessary resources, but it does run fairly quickly and ensures re-sorting and pulling the most updated data.

Thanks again for the thoughtful suggestions.

Hi @55552

I should have also asked you to post your code in Text - the below is OCR'd so spelling may be an issue.

Firstly, your Items - there is only one field here that is relevant
SortByColumns( Filter( AheadWithDates, If( IsBlank(PieceUIDSearch.Selected.ElementNo), Not(PieceUIDSearch.Selected.ElementNo in DATA.ElementNo), PieceUIDSearch.Selected.ElementNo in DATA.ElementNo ) && ( ( ( DelivDateOnly <= (Today() - 1) Or IsBlank(DelivDate) ) && !DispatchedYN ) Or ( DelivDateOnly >= Today() Or IsBlank(DelivDate) ) ) && TotalWtLoadSum > 10 && If( !IsBlank(LotNumSearch.Selected.Value), LotNumSearch.Selected.Value in DATA.lotNumber, ReReq <> "999" ) ), "DelDateSort", SortOrder.Ascending, "ExtStackContainerNo", SortOrder.Ascending )

Your data source Patch is not really relevant
Patch( LoadStatuses, LookUp( LoadStatuses, LoadNumProjID = LoadNumProjectIDHidden.Text ), { ProjectID: varProject, ProjectName: varProjectName, LoadNumInt: varLoadNumber, PiecelD: varPieceList, RequestDate: PickReqDate.SelectedDate, DeliveryDate: PickReqDate.SelectedDate, RequestorEmail: User().Email, ReRequest: If( !IsBlank(PickReqDate.SelectedDate) && varReReq = "Yes", "No" ), UserReqDate: Now() } );

The UpdateIf of the Collection again has one item in question
UpdateIf( AheadWithDates, ExtStackContainerNo = varLoadNumber, { ReqDateOnly: DateValue(Text(PickReqDate.SelectedDate, DateTimeFormat.ShortDate)), ReqDateSort: PickReqDate.SelectedDate, ReqDate: PickReqDate.SelectedDate, DelivDate: PickReqDate.SelectedDate, ReReq: If( !IsBlank(PickReqDate.SelectedDate) && varReReq = "Yes", "No" ), DelDateSort: If( !IsBlank(DelivDateSum.Text), DateValue(DelivDateSum.Text), PickReqDate.SelectedDate ), UserRqDate: Now() } )

So what is in DelivDateSum.Text and have you checked that it (or PickReqDate) is updating the Collection field DelDateSort immediately after this action ?
If it is, Reset the Gallery
Reset(GalleryName)

at the end of the UpdateIf code.

I think the best thing to do, as you suggest, is to run your ClearCollect/SortByColumns/Filter following the date change.

The call to UpdateIf will update the row(s) in the collection, but it won't re-sort the underlying collection, which would explain the behaviour that you're seeing.

Gallery does not re-sort after changing a date

Here is a screenshot of the gallery:

The Items come from a Collection (filtered and sorted), and the Collection is populated from a Dataverse table. Here is the code for the Items property of the gallery.

This code is run when the user selects a Project from the combo box at the top. If necessary, I could also run this code when a date is changed, if there are no other options.

Here is the code in the OnChange property of the date selector to put in the newly selected date: I am updating both the local Collection (that is bound to the gallery items) and the underlying online database table in Dataverse, to permanently save the date change. Both request date and delivery date are updated. A column called DelDateSort is used for sorting. This column is pushed when the user selects the Combo box, and reports a delivery date if present, else use the request date. I am purposely updating this column in the Collection in the code below when the date is changed.

Hi @55552

What Is the Items of the Gallery and what is your data source type ? Also what is the code you use to update the date.
