Hi All,

I need your help in filtering a gallery with multi select combobox :

items of combobox: Distinct(vw_equipment_classification,class_description)

onchange on combobox: ClearCollect(multifilter1, Self.SelectedItems);

gallery items:

Filter(AddColumns(vw_equipment_classification,"class_description2",class_description),class_description in multifilter1))

Please help urgently!

Thanks

@ridhan,

Assuming that class_description is a text field, that Filter code looks good and I would expect it to work.

Would it be possible to provide more information about (1) the error, (2) the column types and (3) the datasource?

Thanks!

@ridhan using the 'in' operator in such a manner indeed will cause a delegation warning. Should your list not exceed the Data Row Limit (default 500, max 2000) then this is nothing to worry about.

A few possibilities you could consider:

(1) Use a single-select dropdown and check whether the selected value equals your column value

(2) Prefilter your data to make sure the output is less than 2000 records. Below a fictive example:

With( //Prefilter with a delegable query to get a sub 2000 record output {wPrefilter: Filter(vw_equipment_classification, ColumnX = ValueY)}, //Non-delegable filter on the prefiltered dataset AddColumns( Filter( wPrefilter, class_description in multifilter1 ), "class_description2", class_description ) )

(3) Move the filter logic to Power Automate by using Stored Procedures or the Execute a Query V2 action. The flow then returns the ouput as a JSON response which is stored to a collection and displayed in the app. (This is generally my go-to approach when using complex non-delegable SQL queries)

I hope this helps!
