Posted on by 11

Hi
I'm Creating simple Application which will have some text inputs.
In Gallery I have Some Text Inputs and in that some of them to be Populated
I need to Populate lets Say " Type" & "Description" Fields in the App Based on "Activity" Field.
When User Enters Data into "Activity" field, the "Type" and "Description" Should Automatically Populate the Corresponding Data.
Populating should happen in new added line also.
I will Keep Activity, Type, Description Data in Excel for lookup.

    Hi @Puneeth656,
    You can use below - 
    1. Default property of Type input control - LookUp(TableName, Activity = ActivityInputControlName.Text).Type
    2. Default porperty of Description input control - LookUp(TableName, Activity = ActivityInputControlName.Text).Description

    Its throws error
    Invalid Use of '.'
    LookUp(ActivityMapping, Activity = Activity.Text).Type

    Lookup Table Name is "ActivityMapping" and Activity field input name is "Activity".

    Hi @Puneeth656 ,
    Try using below- 
    LookUp(ActivityMapping, Activity = Activity.Text, Type)
    If you are not using English locale, replace "," with ";"
