The printed value is the one that is in the database, so that is working fine. However, I don't see how I can show this value within my Radzen application. I'm currently using a mask component but perhaps this isn't the right component.
Basically you need to handle the Then event of the Invoke method action and add a new action of type Set Property where Value is set to ${result} and Name is set to something like tag. Then set the TextBox Value property to ${tag} (from the Property grid).
@korchev Thanks! This is working. However, I want to update this value in realtime. My application is currently waiting for an action while I actually want to see the data when I load the page (so I won't have to click a button). It would be best to have this value updated realtime. Does Radzen have a built-in timer? Or do I need to program that myself?
