Adding dropdown lookup to exisiting form

I have a form That has 3 input files (startdatetime, enddatetime, and employeeid)
The employee id is to be a dropdown wit hthe list coming from the employee table.
Then when the data is saved in the vacation table, the employeeid will will be entered.
I cannot figure out how tom do it. Can someone please help.

Hi @rkmoray,

You can refer to this section from the Radzen documentation. It shows how to populate a component with data coming from a database.

By the way Radzen will automatically create lookups if there is a foreign key constraint by EmployeeId.
