Filter Gallery with multiple selection of checkboxes not working

I have a powerapps gallery with SharePoint as the datasource. 

 

Currently filter functionality has 2 options (Filter by category and Filter by amount). Category is a single line of text field in datasource and Amount is a number field in datasource.

 

Search is working fine. Filter works if i select a single category, however if i select multiple categories it doesnt work. It also doesnt work if i check any amount checkboxes. 

 

I have also included below screenshot of my filter code. May i know where i am going wrong?

 

Main Gallery Items Property

If(
IsBlank(TextInput1.Text) && IsBlank(varSelection),
Items,
Len(TextInput1.Text) > 0,
Filter(
Items,
TextInput1.Text in 'Item Name' || TextInput1.Text in Description || TextInput1.Text in 'Unit Price' || TextInput1.Text in 'Item Category'
),
!IsBlank(varchecked) && IsBlank(TextInput1.Text) && IsBlank(varSelection),
Filter(
Items,
Switch(
varchecked,
"Under $50",
Amount >= 0 && Amount < 50,
"$50 - $100",
Amount >= 50 && Amount < 100,
"$100 - $200",
Amount >= 100 && Amount < 200,
"Above $200",
Amount >= 200
)
),
Filter(
Items,
'Item Category' = varSelection
)
)

 

Filter by Category Gallery - Items Property

Distinct(Filter(Items,'Item Category'),'Item Category')

 

Filter by Category Gallery - OnCheck Property

UpdateContext({varSelection:Gallery3.Selected.Value})

 

Filter by Category Gallery - OnUnCheck Property

UpdateContext({varSelection:Blank()})

 

Filter by Amount Gallery - Items Property

Distinct(Filter(Filter,Amount),Amount)

 

Filter by Amount Gallery - OnCheck Property

UpdateContext({varchecked:Gallery3_1.Selected.Value})

 

Filter by Amount Gallery - OnUnCheck Property

UpdateContext({varchecked:Blank()})

@Iantaylor2050 ,

It is because you are setting a single value for varSelection -  you can only select one Gallery item (I assume these are your checkboxes) at a time

UpdateContext({varSelection: Gallery3.Selected.Value})

This is going to get a little complicated  - so at Screen OnVisible

ClearCollect(
   colSelection,
   {Value: Blank}
)

OnCheck of the Check Box

Collect(
   colSelection,
   {Value: ThisItem.Value}
)

OnUncheck of the Check Box

RemoveIf(
   colSelection,
   Value = ThisItem.Value
)

and the Filter for this part

(
   CountRows(colSelection) = 1 ||
   'Item Category' in colSelection.Value
)

Hi @WarrenBelz , All,

 

Can please assist me on the above? Thanks

Hi @Iantaylor2050 ,

Try this in the Gallery Items  = also confirm that 'Unit Price' is a Text field

Filter(
   Items,
   (
      Len(TextInput1.Text) = 0 ||
      TextInput1.Text in 'Item Name' || 
      TextInput1.Text in Description || 
      TextInput1.Text in 'Unit Price' || 
      TextInput1.Text in 'Item Category'
   ) && 
   (
      IsBlank(varSelection) ||
      'Item Category' = varSelection
   ) &&
   (
      IsBlank(varchecked) ||
      Switch(
         varchecked,
         "Under $50",
         Amount >= 0 && Amount < 50,
         "$50 - $100",
         Amount >= 50 && Amount < 100,
         "$100 - $200",
         Amount >= 100 && Amount < 200,
         "Above $200",
         Amount >= 200
      )
   )
)

Hi @WarrenBelz 

 

Unit Price is a currency field. I tried the above code, however it doesnt work.

 

Whenever the gallery is loaded, it doesnt show any record. Also if i check category filters, no records appear.

 

If i check amount filter, records start appearing in the gallery, however filter doesnt work here. 

@Iantaylor2050 ,

The code is valid assuming there is data matching the various filter parts. I suggest you do some basic debugging first and test each of the elements separately to see if you get data, then the problem should be isolated.  So

Filter(
   Items,
   (
      Len(TextInput1.Text) = 0 ||
      TextInput1.Text in 'Item Name' || 
      TextInput1.Text in Description || 
      TextInput1.Text in 'Item Category'
   )
)

assuming Description , 'Unit Price' and 'Item Category' are all Single Line of Text fields - then

Filter(
   Items,
   (
      IsBlank(varSelection) ||
      'Item Category' = varSelection
   )
)

again assuming 'Item Category' is a Single Line of Text field and finally

Filter(
   Items,
   IsBlank(varchecked) ||
   Switch(
      varchecked,
      "Under $50",
      Amount >= 0 && Amount < 50,
      "$50 - $100",
      Amount >= 50 && Amount < 100,
      "$100 - $200",
      Amount >= 100 && Amount < 200,
      "Above $200",
      Amount >= 200
   )
)

assuming Amount is a Numeric field

Hi @WarrenBelz 

 

I have tested separately each module. Code works fine. Now even the combined code also works fine without any issues. 

 

However if i check multiple categories i.e. Apparels, Health the results shown are incorrect. It only filters by the last checked i.e. by Health.

 

May i know why this happens?

Hi @WarrenBelz 

 

I am trying to modify the above search to additionally include Select All Types and Select All Amount feature as per below screenshot.

 

Iantaylor2050_0-1696301716660.png

 

I have made below code change for the same, but it doesnt work properly. May i know where i am going wrong?

 

Main Gallery Items Property

Filter(
Items,
(
Len(TextInputCanvas1_3.Value) = 0 ||
TextInputCanvas1_3.Value||TextInputCanvas1.Value in 'Name' ||
TextInputCanvas1_3.Value||TextInputCanvas1.Value in Description ||
TextInputCanvas1_3.Value||TextInputCanvas1.Value in 'Price' ||
TextInputCanvas1_3.Value||TextInputCanvas1.Value in 'Category'
) &&
(
(
CountRows(colSelectionGal) = 1 ||
'Item Category' in colSelectionGal.Value
)
) &&
(
IsBlank(varcheckedGal) ||
Switch(
varcheckedGal,
"Under $50",
Amount >= 0 && Amount < 50,
"$50 - $100",
Amount >= 50 && Amount < 100,
"$100 - $200",
Amount >= 100 && Amount < 200,
"Above $200",
Amount >= 200
)
)
)

 

Filter by Types Gallery - Items Property

Distinct(Filter(Items,'Item Category'),'Item Category')

 

Filter by Types Gallery - OnCheck Property

Collect(
colSelectionGal,
{Value: ThisItem.Value}
)

 

Filter by Types Gallery - OnUnCheck Property

RemoveIf(
colSelectionGal,
Value = ThisItem.Value
)

Filter by Types Gallery - Default Property

If(SelectAllTypesCheckbox.Value,SelectAllTypesCheckbox.Value,false)

 

Select All (Types) checkbox - OnCheck

Clear(colSelectionGal);
ForAll(Gallery5.AllItems, Collect(
colSelectionGal,
{Value: ThisRecord.Value}
))

 

Select All (Types) checkbox - OnUnCheck

RemoveIf(
colSelectionGal,
Value = ThisRecord.Value
)

 

Filter by Amount Gallery - Items Property

Distinct(Filter(Filter,Amount),Amount)

 

Filter by Amount Gallery - OnCheck Property

UpdateContext({varcheckedGal:Gallery5_1.Selected.Value})

 

Filter by Amount Gallery - OnUnCheck Property

UpdateContext({varcheckedGal:Blank()})

 

Select All (Amount) checkbox - OnCheck (Code throws error)

Clear(varcheckedGal);
ForAll(Gallery5_1.AllItems, UpdateContext({varcheckedGal:Gallery5_1.Selected.Value}))

 

Select All (Amount) checkbox - OnUnCheck (Code throws error)

RemoveIf(
colSelectionGal,
UpdateContext({varcheckedGal:Blank()})
)

Hi @Iantaylor2050 ,

I would have to build a model to start understanding all of that (which I cannot do presently), but I will give you a couple of tips - you cannot set a Variable inside a ForAll statement

ForAll(
   Gallery5_1.AllItems, 
   UpdateContext({varcheckedGal:Gallery5_1.Selected.Value})
)

this one needs the actual filter criteria for the items to be removed (setting a Variable here is not what it needs)

RemoveIf(
   colSelectionGal,
   UpdateContext({varcheckedGal:Blank()})
)

 

Hi @WarrenBelz 

 

I get an error message stating UpdateContext function cannot be used within ForAll
