Hi @Anonymous,
Do you want to set Id as value to Dropdown and name as display name of control in Dropdown?
If you want to set the Id property value as selected value (Dropdown.Selected.Value) of the Dropdown control, along with the name as the display name of Dropdown control, I afraid that there is no way to achieve your needs in PowerApps currently.
I agree with @Drrickryp's thought almost. I have made a test on my side, please take a try with the following workaround:
Set the Items property of the Dropdown control to following:
'[dbo].[Employees]'
On your side, you should type:
'[dbo].[YourSQLTable]' /* <-- Type your SQL Table */
Set the Value property to a column in your SQL table, which you want to display within the Dropdown control.
If you want to get/reference Id property value of selected value within the Dropdown control (Dropdown1), please take a try with the following formula:
Dropdown1.Selected.Id
Best regards,
Kris
