I made some development on a form by adding a new button and writing code in its OnPush trigger.
I should do the same alteration on the connecting page. Is there any similiar possibilites for this? I did not find anything.
Thanks in advance
You have to transform the form to page by using transformation tool.
If you want to do it directly in the Page Designer add an Action to the Page and set the Promoted property for this action to Yes. The Action has an OnAction trigger to put your code in.
Here a link how to add an action.
