Filter dropdown choices based on a number

Hi guys,

 

I have this text data card where i input numbers and a dropdown menu with cities. I would like to make the dropdown choices available based on the number that i type in. 

The numbers will always have the same format, 10 digits and in the middle, the city code. The other digits will be random.

1232065231 - New York,Baltimore, Boston

1233085345 - Los Angeles, San Francisco

 

Purpose of this is that i would like to restrict users when they input a number. to select the wrong city.

Hi @Babalaul

 

I would use a table like @PK_Hong is suggesting.

Maybe like :

ClearCollect(citytable,

{Citycode:"065",cityname:"New York"},

{Citycode:"065",cityname:"Baltimore"},

{Citycode:"065",cityname:"Boston"},

{Citycode:"085",cityname:"Los Angeles"},

{Citycode:"085",cityname:"San Francisco"}

)

 

And if you want to extract the city number from a larger textInput, I would use the Mid() function :

 

Dropdownlist.Items : Filter(citytable,Citynumber=Mid(TextInput.Text,5,3) )

Re: Filter dropdown choices based on a number

Try setting the DataCard.Update to :

 

{'@odata.type':"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
   Id:0,
  Value : DropDownList.Selected.Value}

 

SharePoint is expecting this kind of object in it's Choice column.

 

So this is the kind of oject that is going to be stored and retrieve to PowerApps as the default value of the drop-down when you'll try to update your Item.

I think that you'll need to change the default value of the DataCard to match your Excel table items :

 

Dropdownlist.default:

LookUp(dropdownDataSource,Value=ThisItem.ChoiceColumn.Value)

Hi @Babalaul

 

You need to have a table such as below:

TableCity

Code    City

065       New York, Baltimore, Boston

085       Los Angeles, San Francisco

etc.

 

TextInput1 = (to ente code)

Dropdown shall be = Distinct(TableCity, LookUp(TableCity, TextInput1.Text = Code).City)

 

example:

TextInput1 bxox - 065

Distinct will filter TableCity where the entered code match the code in TableCity, and then show the matching CITY

 

Wish my wild guess is correct.

Have a nice day.

Re: Filter dropdown choices based on a number

Hello,

 

In SharePoint is a "Choice column" , with the same city names that i have inputed in my excel table.

Update Property = Datacard.Selected

The way i submit the form is trough a save button , wich has on select = submit(form)

Re: Filter dropdown choices based on a number

Actually it was much easier that i tought. I removed the dropdown menu and created a new one. Insrted the formula, connect it to the datacard and it works. Now it saves in my Sharepoint list.

 

Thanks
