Real-Time Progress Loader

0

Hi All, How can I display a real-time loader with percentage progress in Mendix? For example, I have a parent nanoflow that executes around 25 activities, including some sub microflows/nanoflows. I’d like to show a loader that updates dynamically — for instance, once the first 12 activities are completed, the loader should display 50% progress. Any suggestions to achieve this in Mendix? Thanks, Guna

You could use something like the Progress Bar from the marketplace to show your progress. You would have to update the attribute that's shown in the progress bar in your nanoflow after completing each subsection.

However, you also have to consider what this does for your user. If the progress bar is halfway full, they'll assume the process is halfway done - but it could be that the second part of the process takes much longer because it has much heavier actions. It's one of the reasons many companies have switched to just spinning circles or other repeating animations, because progress bars are notoriously inaccurate and don't really tell you that much more.
