Can't find the way to integrate Data Service into Apps dropdown list

[hongjoo.choi (HongJoo （崔弘周）)]

Hi, Forum.

How can I integrate the Entity to Dropdown list in Apps. When “=” is clicked inside the List box in Apps, there supposed to be “resource” pannel shows up, but nothing happens. Something seems have changed in the recent version (24.10.5) but I can’t find it. Can anyone help out?

Hello again @hongjoo.choi !

Happy to help you,

Here you want to fetch dropdown from items found in DataService.
Here is how to achieve this, you will see it is pretty easy but again, it has entirely changed from legacy apps to now apps with vb expressions.

You’ve already added Entities so in your drop down:

1:Click ListSource the “Open Resources” button next to it
2: Click Query Builder
3: In the Select Source, select your entity
4: If needed, add conditions ( for instance: Where field Active = True ), you also have “Additional settings” available to sort results.
5: Click Save
6: Now you have items fetched from your DataService, but you need to tell app, which field from your entity you want to show to the user. Just below “List source” you have “Column” property, they expect you to put property name from entity.

Hope this help

@hongjoo.choi,

Follow these steps:

1. Click on Config icon of List source and Select Query Builder
   

   

2. Select the entity you desired and click save. Here mine is Test
   

   

3. Your List Soruce should be look like this one.
   

   

4. Now navigate to Entities and select your entity. From here we need to take the Field name which could be different from Display Name

6. Now go back to design page where our dropdown is and enter the Field name we copied in step 5 in Column
   
   

That’s it.
