Posted on by FA-17040949-0

I have two modern tables in my Screen. OpenInvoices and "AllInvoices". They are visible if they are chosen in Toolbar.

I have an issue with SelectedItems. It seems SelectedItems is not working for this table?

You have not explained the problem that you are getting what is the structure of the collection?

Besides that the modern table is still in preview and may not be fully functional.

@stampcoin I searched the web and fount out that if I reduce the table height to approx 672 so it maximum shows 14 items, and turn of flexible height for the modern table, then it works, but only if I do not scroll.

My table has approx 400 items. When table is refreshed, i can click on items, and selecteditems count works. Once I scroll, selecteditems is set to 0 again.

@MS.Ragavendar

I can select items, and it counts with countrows (selectedItems), but if you then scroll down to select more, then the selection shows zero.

I believe there are two problems that showed up here.

In the first example, I am guessing you are trying to collect a value in a specific column? If so, then consider the following PowerFx instead

ClearCollect( varSelectedInvoices ForAll(OpenInvoices.SelectedItems, Faktura); ForAll(AllInvoices.SelectedItems, Faktura) );;

As for the CountRows, Microsoft has reported that the function doesn't work well for collections that update live. Try to use this PowerFx instead.

CountIf(OpenInvoices.SelectedItems, true) CountIf(AllInvoices.SelectedItems, true)

Let me know if you have a more accurate result with these modifications.

@venturemavenwil I have simplified my table to only be one table, and toggled the view to show All or only open. I have added a gif showing what happens.

When you start selecting, The "Fakturakopi ()" counter works fine. When you start browsing, the counter goes to 0.

But at the bottom of the table it shows the correct selected item numbers.

When clicking the button "Fakturakopi" the collection is either blank or only the items that sometimes are shown as selected.

Maybe i have to change the table onSelect code to add to collection as an item is clicked as a workaround?

Update: Tested, not working. The OnSelect triggers only "sometimes", not all the time.

SortByColumns( Filter( Invoices; If(varShowOpenOnly; Status = "Open"; true); varReset ); "Dato"; SortOrder.Descending )

For the Toolbar "OnSelect", i changed it to:
"send_email"; ClearCollect(varSelectedInvoices; ForAll(OpenInvoices.SelectedItems;Faktura));;

The code to count how many i have selected is:
{ ItemKey: "send_email"; ItemDisplayName: "Fakturakopi (" & CountRows(OpenInvoices.SelectedItems) & ")"; ItemIconName: "Mail"; ItemAppearance: "Subtle"; ItemIconStyle: "Regular" };

Could you change all instances of CountRows to CountIf(<collection>, true)? That is one reported problem - CountRows doesn't always update live.
