Controls limitations

On Xojo Web how many controls can I display simultaneously ?
I’m working on a text based game and I plan to have over 300 webbuttons on screen .
Is this too much ?

You can easily test this by yourself:
place a button within a containercontrol, go to your main page and embed 300+ of them into the page.

We have layouts with hundrets of different controls at the same time displayed and the performance is good. The only performance issue you can produce is, if you embed the 300 + buttons while running shown- and open-events for each of them. then the loading time could be not so good.

Also if you plan to have a lot of mouse-events. this could also drop your performance.
