ComboBox and DropDown only allow a maximum of 800 items

Hi.

I have a Canvas App Page inside a Model-Driven App Solution. I have a function as follows:

ClearCollect(SitesDropdown, SortByColumns(ForAll(Sites, {SiteId:Site ,Position: Value(SiteCode), SiteCode: SiteCode, Description: SiteCode & " - " & Name}),"Position",SortOrder.Ascending));

This has 807 entries, but I am only seeing 800. My Settings has been updated to allow 2000. I have no idea what is causing this as when I view the Collection by clicking on it it has all 807 records. I messed about with screen size and this definitely has an impact on what is displayed.

Can anyone help?

Thanks.

John.

Re: ComboBox and DropDown only allow a maximum of 800 items

I noticed this limit of 800 in the Modern Combobox. It's not driven by the app data row limit. The tricks with:
- Filter( MyTable , cbx_comboboxname.SearchText in MyColumn ) or
- Search( MyTable , cbx_comboboxname.SearchText , MyColumn ) did help with search in the Modern Combobox but the items beyond the 800 that did show up in the dropdown were unselectable/unclickable.

Switching to Classic Combobox helped. It doesn't look as nice but it does the trick. The entire table.column (in my case 3,600 items) is searchable and selectable.

Hi @johnguilbert191 ,

This is a limitation with the modern controls used in custom pages. This is the same experience for the modern drop down control in standalone canvas apps.

2 options:

1) open a standalone canvas app. Add a classic dropdown control. Copy & paste it into your custom page,
or
2) consider open source component libraries, such as this one from Luise Freese & Robin Rosengrun
