Posted on by Microsoft Employee

Hi 

In a form i have three dropdowns

data has to populate from 2 tables actually

List1 columns(department,JobTitles)

List2 columns(Location)

 

Dropdown1

Formula is (Distinct(list1,Departments)  Working as fine as expected

Dropdown2(when Dropdown1 selected value then only dropdown2 values are loding) Working as fine as expected

Formula is Filter(list1,Departments=dropdown1.Selected.Result)

Dropdown3

1. when dropdown2 is selected then only dropdown should be active to select values

2. how to load(farmula) from list2 columns

or

do i need to create lookupcolumn in list1 even tho i tryed with below formula but data is not populating 

i tried with below formula

Distinct(Filter(kmkPowerAppsTest,Departments=drp_dept.Selected.Result), lookulocation)

waring : columns produced by this rule are all nested tables and or/recoreds however the properties expects atlest some columns of the simple values

 

how to fix this error can some one kindly help me how to load dropdown3 from list2

    If drop down 3 is only going to show Locations based on the first two drop downs then what is the field that list 1 and 2 have in common?

    Hi @Anonymous ,

     

    Is "kmkPowerAppsTest" the name of list2? What are these parameters "drp_dept" and "lookulocation" refer to since you didn't mention them in your description?

     

    One Form control can only have one data source. If you want to use a 2nd data source (list2 in your case) in a Form control to update the record for the 1st data source, then you could try to use the 3rd dropdown control separately from the Form control. That is to say, please add the 3rd dropdown control as a standalone control ourside of the Form control. Then use a Patch function to update records to your data source.

     

    The Patch formula could be something like:

    Patch('Data Source', BrowseGallery1.Selected, { Flavor: “Strawberry” })

     

    Regards,

    Mona
