Filtering the gallery from multiple sources

Report

Posted on by Community Power Pla... Microsoft Employee

I'm experiencing code block here.

What I'd like to do:

Filter a gallery of mobile phones
- Filtering by the cell phone's battery capacity ( i.e. 3500 mAh)
- Filtering using two or three pickers: 1 list box and 1 single dropdown list, each is connected to a different database

What the issue is:

the code I put in there does not seem to have the right syntax.

Code (right on the "Item" of the gallery called resultDisplayFinal:

Filter(
resultDisplay.AllItems,
Storage >= Max(
UseList.SelectedItems,
storageUse
),
Memory >= Max(
UseList.SelectedItems,
memoryUse
),
Battery >= Max(
Filter(
Table1_1,
frequencyOptions = DayTimeFrequency.Selected
),
batteryUse
),
Display >= Max(
UseList.SelectedItems,
displayUse
),
Camera >= Max(
UseList.SelectedItems,
cameraUse
)
)

Hi @Anonymous ,

Which data source does your resultDisplay connect to?

Based on the formula that you provided, I think there is something issue with it. The First argument of your Filter function should be the data source your resultDisplay connect to rather than resultDisplay.AllItems.

Please consider modify your formula as below:

Filter( 'YourDataSource', Storage >= Max(UseList.SelectedItems, storageUse), Memory >= Max(UseList.SelectedItems, memoryUse), Battery >= Max(Filter(Table1_1,frequencyOptions = DayTimeFrequency.Selected),batteryUse), Display >= Max(UseList.SelectedItems, displayUse), Camera >= Max(UseList.SelectedItems, cameraUse) )

Note: The 'YourDataSource' represents the data source your resultDisplay connect to.

Hi @Anonymous ,

Is there something error with the formula you provided?

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned. Please check if you have typed proper Filter conditions within the Filter function.

Based on the conditions that you provided, it would filter your data source records whose Storage column value is greater than the maximum Storage value of these selected items in your list box, and Memory column value is greater than the maximum Memory value of these selected items in your list box, and Battery column value is greater than the maximum Battery value of these selected items in your list box, and Display column value is greater than the maximum Display value of these selected items in your list box, and Camera column value is greater than the maximum Camera value of these selected items in your list box.

Please check if there are records which meet above filter conditions existed in your data source. You could take a try with following formula in your Gallery:

Filter( 'YourDataSource', Storage >= Max(UseList.SelectedItems, storageUse) )

Filter( 'YourDataSource', Memory >= Max(UseList.SelectedItems, memoryUse) )

Filter( 'YourDataSource', Battery >= Max(Filter(Table1_1,frequencyOptions = DayTimeFrequency.Selected),batteryUse) )

...

...

then check if the proper records could be displayed in your Gallery. If true, I think there may have something issue with the Filter conditions you typed in your Filter function.

Best regards,

Hi Kris,

I'm attaching some screens.

So when I tried just
Filter( 'YourDataSource', Battery >= Max(UseList.SelectedItems, batteryUse) )
It seemed to work no problem ( see first screen)

then I applied
Filter( 'YourDataSource', Battery >= Max(Filter(Table1_1,frequencyOptions = DayTimeFrequency.Selected),batteryUse) )

and it doesn't seem to work, and came with warning sign ( see 2nd and 3rd screens)

Did I do something wrong?
