Hi Shriram,
To achieve this, you can use a small workaround since the "Validate Details" button is outside Mendix control. When the user clicks this button, your external form triggers a POST callback to your Mendix Published REST API. In that API logic, you can update a non-persistent helper entity (e.g., FormStatus
) with a flag like IsFormSubmitted = true
. On the Mendix page where the iFrame and the "Your Details Saved" container exist, use a Microflow Timer (available from the Mendix Marketplace) to periodically check this flag by calling a microflow. Once the flag is set to true, you can update a visibility condition or use a page parameter to hide the iFrame and show the confirmation container. This lets your Mendix UI react to an event that happened outside its usual lifecycle, in a clean and reactive way.
Let me know, if you have any issues,
Hope it helps!
