Combining Filter and Sort

[Tezz233]

I have the following Sort in my Gallery:

SortByColumns(Search('Table', TextSearchBox1.Text, "First_Name", "Surname","Address_Line_1"), "Postcode")

My question is, is there a way to Filter the results before Sorting? Essentially, I want to add a Filter that checks if Area_ID is equal to something specific such as 12345 and then, once filtered, I want the Sort above to kick in. Any suggestions? I tried combining the Filter and Sort into one statement, but I alwas seem to get errors.

That should work - you should be able to compose multiple table operations (sorting, searching, filtering, etc.). For example, in your scenario, try something like this (you may need to change the field names / values):

SortByColumns(
    Search(
        Filter(
            'Table',
            Area_ID = 12345),
        TextSearchBox1.Text,
        "First_Name",
        "Surname",
        "Address_Line_1"),
    "Postcode")

Nevermind, the above is working now. Just had to refresh my data to fix the bug.

Actually, just noticed a problem @CarlosFigueira. If I filter by Area_ID first, and then enter a postcode, the search seems to overwrite the filter and show Area_IDs that should be filtered out. For example...

Area_ID  PostCode

123         HA0 111

123         HA0 112

123         HA0 113

111          HA2 11G

If I filter the Area_ID by 123, only the first 3 results show which is good. However, if I then search by a postcode such as "HA", the fourth result with the 111 Area_ID will show up because the search is overwriting the filter. I'm hoping to get the two working together so that once I filter by a Area_ID, the search will only act on the filtered results that are showing.

Do you have any solution to the last post, to avoid that the search-function is overwriting the filter?
Please update

@Tezz233 I don't see the problem of the search overriding the filter... To try to reproduce this scenario, here's what I did:

- Added a button to an empty screen with the following OnSelect expression:

ClearCollect(coll,
    {Area_ID:123, PostCode:"HA0 111"},
    {Area_ID:123, PostCode:"HA0 112"},
    {Area_ID:123, PostCode:"HA0 113"},
    {Area_ID:111, PostCode:"HA2 11G"})

Added a gallery, and inside the gallery added a label with the expression

ThisItem.Area_ID & " - " & ThisItem.PostCode

Then set the Items property of the gallery to the filter/search expression:

Search(Filter(coll, Area_ID = 123), "HA", "PostCode")

The gallery displayed only the three items with Area_ID = 123, it didn't display the fourth one.

To check if this is a problem with delegation, I also created a new table in a SQL Server database:

create table forumpost_85212 (
    Id int identity(1,1) primary key,
    Area_ID int,
    PostCode nvarchar(max)
)

And added four items to it:

insert into forumpost_85212 (Area_ID, PostCode) VALUES (
    123, 'HA0 111'
)

insert into forumpost_85212 (Area_ID, PostCode) VALUES (
    123, 'HA0 112'
)

insert into forumpost_85212 (Area_ID, PostCode) VALUES (
    123, 'HA0 113'
)

insert into forumpost_85212 (Area_ID, PostCode) VALUES (
    111, 'HA1 11G'
)

Likewise, after adding a data source pointing to that table, I set the gallery's Items property to:

Search(Filter('[dbo].[forumpost_85212]', Area_ID = 123), "HA", "PostCode")

And once again I only see three items.

Can you post more details on where you are seeing the Search function overriding the Filter expression?

Hi,

I know this an old post but I'm having the same problems, the Search function always overrides the Filter results. I have tried all the suggestions in posts but always the same, the results are correctly filtered by the Dropdown1 & Dropdown1_2 selections but if I search via TextSearchBox1.Text the results are from the entire database and not filtered.

SortByColumns(

    Search(

              Filter('MG Site',

                        SiteID = Dropdown1.Selected.Value, EntType = Dropdown1_2.Selected.Value

                        ),

                        TextSearchBox1.Text,

                        "UnitNo",

                        "IPAdd),

                        "IPAdd",

If (SortDescending1, Descending, Ascending)

)

Would appreciate some help please.

Hi Jeff,

Realise this is an old post!

But came across it researching a similar (though not exactly the same) question.

For me it's liked 'related' or 'constrained' dropdowns.

User selects the "Market" and then a list of "Manufacturing Centres" are related to "Markets".

I couldn't seem to combine the sort and filter. But I used ClearCollect statement in the "OnSelect", seemed to work OK so far!

e.g. (this is on the 2nd field!)

OnSelect
ClearCollect(tempCollection,Sort('[dbo].[vwMarketManufacturingCentre]',MANUFACTURINGCENTRE))

And the "Items" field (the other options mean it can be blank, and blank on selection).

Ungroup(Table({Item:Blank()},{Item:Filter(tempCollection,MARKETNAME = MarketSelection_1.Selected.Value)}),"Item")

It seems to work - probably needs more testing (I'm expecting to need to "Clear" the tempCollection collection!

[ShowMeTheAnswer]

Here's another more complicated "Sort and Filter" example.

It worked when my other approach didn't!

Ungroup(Table({Item:Blank()},{Item:Distinct(Filter(Sort('[dbo].[KAPMT_MAIN_VIEW_2]',PROCESS_STEP_DESC,Ascending),
APPLICATION=ApplicationSelection_1.Selected.Value,SITE_DESCRIPTION=SiteSelection_1.Selected.Value,MANUFACTURINGCENTRE=ManufacturingCentreSelection_1.Selected.Value,MARKETNAME=MarketSelection_1.Selected.Value),PROCESS_STEP_DESC)}),"Item")

Bumping this thread up again.  I have run into an issue with my app only pulling 500 records and I understand that limit can be adjusted a bit but what I want to do is just filter the retrieval of records to ones where my office365 user display name matches the person who submitted the record (which is also the office 365 display name).  

I'm using where FormQs is a live onedrive document where the data resides, Field1 is the name of who submitted the record and Field 2 is the location:  

SortByColumns(Search([@FormQs], TextSearchBox1.Text, "Field1","Field2_(Campus)"), "Date_of_Visit", If(SortDescending1, Descending, Ascending))

I want the app to only pull records where in 'Field1' the name agrees with the logged in user and then allow for search by 'Field2' and Sort by 'Date of Visit'.  

My text search box contains by default: Office365Users.MyProfile().DisplayName which I was trying to use as a workaround so everyone doesn't see everyone else's records but I think it is still pulling all of the records down because if you remove the name that appears in the default we see all records of course. 

I'm trying to reduce the number of records the app pulls when it loads for each user and then still allow searching and sorting from the gallery.  

Thank you
