Dropdown value not saved

Hello,

I converted a "Add Page" to a template and have add a Dropdown to the page as it is described here :

The Dropdown is connected to a table using Data-Property and when I run the app and open the Add-Page I can select something from the Dropdown.

But when I click the "Save" button the value that I have selected from the Dropdown is not saved.
How could I save the selected value ?

How Value property is bound in your case? Usually is like this:

In addition check the Unbound TemplateForm section from our documentation - when the Value of the input components isn't set (so called "unbound template form" case) you have to set their Name property as the DB column name e.g. ProductName.
