When using AddColumns for the gallery, I had been feeling a slight discomfort for some time, so I did some research and found some interesting articles, so here are some notes.
Articles found in this issue
Here is the article we found this time.
The conclusion seems to be that AddColumns cannot be delegated.
AddColumns cannot be delegated.
No delegation warning is displayed for AddColumns.
The first introductory article states that Power Apps Studio’s delegation warning should not be overstated.
Can’t DropColumns and ShowColumns also be delegated?
Cannot be displayed using Dataverse as the data source
Conclusion, even in Dataverse, when AddColumns is used with DropColumns, the gallery will no longer display all data.
Finally.
However, there is no mention anywhere (as far as I know) that delegation is not possible because it ‘cannot be displayed in the gallery’, so it is possible that delegation itself is possible just because it cannot be displayed in the gallery.
However, AddColumns is obviously not delegated as it makes the app run slower.
In any case, when putting these functions into the gallery Items, it will be necessary to assume that all the data will not be displayed and may not be delegated.
