Posted on by Tbabe

i Have a combobox that is suppose to filter a gallery, but i discovered, when i select multiple data, it only pulls the last data selected and not all that was selected. e.g in my combobox, i have A,B,C,D. if i select A, it shows A in my Gallery, if i select A,B, it shows B only in my Gallery instead of A and B. the below is my combobox expression and Gallery expression

cmb_InformationType(Item Properties)=Filter(Choices('Class Information'.'Information Type'),Trim(Value) in "Mathematics|Geography|Physics|Anatomy")

Informationgallery(Items Properties)= Filter(colInformation,cmb_InformationType.Selected.Value in 'Information Type'.Value || IsBlank( cmb_InformationType.Selected.Value)

my Collection formula = ClearCollect(colInformation,'Information Management');

So to be clear...

You have a choice column in your datasource that allows multiple selections and you want to be able to filter by a multiple selection combobox. Is that correct??

Also, what is your datasource?

Your formula then will need to be this:

Filter(colInformation, Sum( ForAll(cmb_InformationType.SelectedItems, If(Value in 'Information Type'.Value, 1, 0)), Value ) > 0 || IsBlank( cmb_InformationType.Selected.Value) )

This is just one of a couple ways to approach this. The concept is to look at each selected item and then see if it is in the table of choices in the column. If so, then it all gets summed up and if the sum is greater than 0, then there was a match and thus the row should be returned.

it didn't give errors, but when i select from the combobox it doesn't return anything. The formula you shared was used in the itemgallery
